The below steps describe how to measure CPU temperature and how to stress individual cores of CPU. Steps are explained with an example of LX2160A SoC. However, these steps are applicable to all Layerscape devices. Download Flexbuild and add packages in Yocto tiny Generate Yocto tiny userland Enable thermal monitoring unit and build kernel Generate .itb image Load .itb image from TFTP server to Layerscape board Validate stress package and measure CPU temperature before and after stress Step 1: Download Flexbuild and add packages in Yocto tiny On a Linux machine, download Layerscape Software Development Kit - <version>. Go to Download tabs at http://www.nxp.com/lsdk. Enter login details, accept the agreement to download the Flexbuild source tarball in the name format flexbuild_<version>.tgz. Run the following commands to extract Flexbuild files from tar archived file. $ tar xvzf flexbuild_<version>.tgz $ cd flexbuild_<verison> $ source setup.env $ flex-builder -h Add “stress” package to "IMAGE_INSTALL_append" parameter of local_arm64_tiny.conf file available in flexbuild_<version>/configs/yocto/ folder. Save and exit the file. Step 2 – Generate Yocto tiny userland Change directory to flexbuild_<version>. Clean obsolete cache data. This step is needed in case source/config has changed. $ source setup.env $ flex-builder -i clean-rfs -r yocto Run the following commands to generate Yocto-based tiny userland: $ flex-builder -i mkrfs -r yocto:tiny $flex-builder -i mklinux -r yocto:tiny $ flex-builder -i mkfw -m <machine_name> -b sd This generates the following images: rootfs_lsdk<version>_yocto_tiny_arm64.cpio.gz (~22M), lsdk<version>_yocto_tiny_LS_arm64.itb, and firmware_<machine_name>_uboot_sdboot.img. For example: rootfs_lsdk2004_yocto_tiny_arm64.cpio.gz (~22M), lsdk2004_yocto_tiny_LS_arm64.itb, and firmware_lx2160ardb_rev2_uboot_sdboot.img Step 3 Enable system monitoring unit and build kernel Change directory to flexbuild_<version>/packages/linux/linux. Enable environmental setting for cross-compiling. The following setting is applicable when you configure and build kernel on a different architecture from the target. For example, compiling an Armv8 kernel on an X86 computer. Run the following commands on Ubuntu Linux: $ export CROSS_COMPILE=aarch64-linux-gnu- $ export ARCH=arm64 Run make menuconfig command to configure settings to enable thermal monitoring unit. $ make menuconfig The command opens the kernel configuration [tree-view structure] prompt. Use the Arrow keys to navigate the menu and Enter to select the submenu. Navigate to Device Drivers --> <*> Generic Thermal sysfs driver --> [ ] Generic CPU cooling support option. Press Y key to include the option. [*] symbol indicates the option is included (shown in below figure). Similarly, include the following options to enable thermal management framework. After you include all options as mentioned in the above table, save the configuration with a file name. For example,  save the configuration file as thermal.config. Exit to come out of the Kernel Configuration prompt. Copy the configuration file to arch/arm64/configs folder. $ cp <config filename> arch/arm64/configs/ For example, $ cp thermal.config arch/arm64/configs/ Configure the kernel. Load the changed configuration for Layerscape Armv8 platform in 64-bit mode for LSDK. $ export CROSS_COMPILE=aarch64-linux-gnu- $ export ARCH=arm64 $ make distclean $ make defconfig <config filename> Build kernel image and device tree image. $ make -j8 Step 4 - Generate .itb file Generate .itb file, which includes stress package and thermal monitoring unit installed, for kernel booting. Copy the Image and Image.gz files from the /flexbuild_<version>/packages/linux/linux/arch/arm64/boot folder and to the /flexbuild_<version>/build/linux/kernel/arm64/LS folder. Change directory to flexbuild_<version>. Generate .itb image using flex-builder. $ source setup.env $ flex-builder -i mkitb -r yocto:tiny This generates lsdk2<version>_yocto_tiny_LS_arm64.itb file. For example, lsdk2004_yocto_tiny_LS_arm64.itb file. Copy the .itb image to the TFTP server. Step 5 - Load .itb image from TFTP server to Layerscape board Set up Ethernet connection between the board (for example, LX2160ARDB) and host machine on which you have configured the TFTP server. Boot the board to U-Boot prompt. U-Boot prints a list of enabled Ethernet interfaces. For example, LX2160ARDB U-Boot prints following Ethernet interfaces. DPMAC2@xlaui4, DPMAC3@xgmii, DPMAC4@xgmii, DPMAC5@25g-aui, DPMAC6@25g-aui, DPMAC17@rgmii-id, DPMAC18@rgmii-id  Set server IP address to the IP address of the host machine on which you have configured the TFTP server . => setenv serverip <ipaddress1> Set ethact and ethprime as the ethernet interface connected to the TFTP server. See LX2160ARDB Ethernet Port Mapping for the mapping of Ethernet port names appearing on the chassis front panel with the port names in U-Boot and Linux. =>   setenv ethprime <name of interface connected to TFTP server> For example: => setenv ethprime DPMAC3@xgmii => setenv ethact <name of interface connected to TFTP server> For example: => setenv ethact DPMAC3@xgmii Set IP address of the board. You can set a static IP address or, if the board can connect to a dhcp server, you can use the dhcp command.  Static IP address assignment: => setenv ipaddr <ipaddress2> => setenv netmask <subnet mask> Dynamic IP address assignment: => dhcp Save the settings. => saveenv Check the connection between the board and the TFTP server. => ping $serverip Using DPMAC3@xgmii device host 192.168.2.1 is alive Load the .itb image from TFTP server to DDR memory of the board. => tftp 0xa0000000 <itb_file_name> For example: => tftp 0xa0000000 lsdk2004_yocto_tiny_LS_arm64.itb Boot the kernel with .itb image as follows: => bootm 0xa0000000#<board_name> For example: => bootm 0xa0000000#lx2160ardb Let the board boots to Tiny Linux. Step 6 – Validate stress package and measure CPU temperature before and after stress Check stress-ng package using which stress-ng command: # which stress-ng /usr/bin/stress-ng Check scaling_current_frequency of the cores. # cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq  For example: Check frequency of 16 cores of LX2160ARDB as follows: Check the temperature of the CPU before applying stress. # cat /sys/class/thermal/thermal_zone*/temp Apply stress by executing following command: # stress-ng -c 8 -i 1 -m 1 --vm-bytes 128M -t 60s & The command applies stress for 60 seconds. For more information on stress-ng command, run stress-ng -h command for help. Check the temperature of the CPU after applying stress. # cat /sys/class/thermal/thermal_zone*/temp For example:

The below steps describe how to measure the CPU power using sensors and also describe how to stress individual cores of CPU. Steps are explained with an example of LX2160A SoC. However, these steps are applicable to all Layerscape devices. Download Flexbuild and add packages in Ubuntu:Lite Generate Ubuntu-based Lite userland (Ubuntu:Lite) Enable system monitoring unit and build kernel Generate .itb image Load .itb image from TFTP server to Layerscape board Validate stress package and measure CPU power using sensors Step 1: Download Flexbuild and add packages in Ubuntu:lite On a Linux machine, download Layerscape Software Development Kit - <version>. Go to Download tabs at http://www.nxp.com/lsdk. Enter login details, accept the agreement to download the Flexbuild source tarball in the name format flexbuild_<version>.tgz. Run the following commands to extract Flexbuild files from tar archived file. $ tar xvzf flexbuild_<version>.tgz $ cd flexbuild_<verison> $ source setup.env $ flex-builder -h Add packages for stress and power sensors in the additional_lite_packages_list file available in the flexbuild_<version>/configs/ubuntu/ folder. Add ‘stress’ and ‘lm-sensors’ packages for Ubuntu Lite as shown below: Save and exit the file. Step 2 – Generate Ubuntu:Lite image Change directory to flexbuild_<version>. Clean obsolete cache data. This step is needed in case the source/configuration has changed. $ source setup.env $ flex-builder -i clean-rfs -r ubuntu:lite Generate Ubuntu-based Lite userland using the following command: $ flex-builder -i mkrfs -r ubuntu:lite This generates rootfs_lsdk<version>_ubuntu_lite_arm64 file. For example: rootfs_lsdk2004_ubuntu_lite_arm64 file. Pack userland in tgz format (Optional step). $ flex-builder -i packrfs -r ubuntu:lite For example: rootfs_lsdk2004_ubuntu_lite_arm64.tgz (~180 M)   Step 3 Enable system monitoring unit and build kernel Change directory to flexbuild_<version>/packages/linux/linux. Enable environmental setting for cross-compiling. The following setting is applicable when you configure and build kernel on a different architecture from the target. For example, compiling an Armv8 kernel on an X86 computer. Run the following commands on Ubuntu Linux: $ export CROSS_COMPILE=aarch64-linux-gnu- $ export ARCH=arm64 Run make menuconfig command to configure settings to enable system monitoring unit for sensing power. $ make menuconfig The command opens the kernel configuration [tree-view structure] prompt. Use the Arrow keys to navigate the menu and Enter to select the submenu. Navigate to Device Drivers --> <*> Hardware Monitoring Support --> [M] Texas Instruments INA219 and compatibles option. Device Drivers-->Hardware Monitoring Support Press Y key to include the option. [*] symbol indicates the option is included (shown in below figure). This enables INA220. Texas Instruments INA219 and Compatibles option included Similarly, include the following options to enable I2C block device driver support and I2C bus multiplexing PC9547. Kernel Configure Tree View Option After you include all options as mentioned in the above table, save the configuration with a file name. For example,  save the configuration file as power.config. Exit to come out of the Kernel Configuration prompt. Copy the configuration file to arch/arm64/configs folder. $ cp <config filename> arch/arm64/configs/ For example, $ cp power.config arch/arm64/configs/ Configure the kernel. Load the changed configuration for Layerscape Armv8 platform in 64-bit mode for LSDK. $ export CROSS_COMPILE=aarch64-linux-gnu- $ export ARCH=arm64 $ make distclean $ make defconfig <config filename> Build kernel image and device tree image. $ make -j8 Step 4 - Generate .itb file Generate .itb file, which includes stress package and thermal monitoring unit installed, for kernel booting. Copy the Image and Image.gz files from the /flexbuild_<version>/packages/linux/linux/arch/arm64/boot folder and to the /flexbuild_<version>/build/linux/kernel/arm64/LS folder. Change directory to flexbuild_<version>. Generate .itb image using flex-builder. $ source setup.env $ flex-builder -i mkitb -r ubuntu:lite This generates lsdk<version>_ubuntu_lite_LS_arm64.itb file. For example, lsdk2004_ubuntu_lite_LS_arm64.itb Copy the .itb image to the TFTP server. Step 5 - Load .itb image from TFTP server to Layerscape board Set up Ethernet connection between the board (for example, LX2160ARDB) and host machine on which you have configured the TFTP server. Boot the board to U-Boot prompt. U-Boot prints a list of enabled Ethernet interfaces. For example, LX2160ARDB U-Boot prints following Ethernet interfaces. DPMAC2@xlaui4, DPMAC3@xgmii, DPMAC4@xgmii, DPMAC5@25g-aui, DPMAC6@25g-aui, DPMAC17@rgmii-id, DPMAC18@rgmii-id  Set server IP address to the IP address of the host machine on which you have configured the TFTP server . => setenv serverip <ipaddress1> Set ethact and ethprime as the ethernet interface connected to the TFTP server. See LX2160ARDB Ethernet Port Mapping  for the mapping of Ethernet port names appearing on the chassis front panel with the port names in U-Boot and Linux. =>   setenv ethprime <name of interface connected to TFTP server> For example: => setenv ethprime DPMAC3@xgmii => setenv ethact <name of interface connected to TFTP server> For example: => setenv ethact DPMAC3@xgmii Set IP address of the board. You can set a static IP address or, if the board can connect to a dhcp server, you can use the dhcp command.  Static IP address assignment: => setenv ipaddr <ipaddress2> => setenv netmask <subnet mask> Dynamic IP address assignment: => dhcp Save the settings. => saveenv Check the connection between the board and the TFTP server. => ping $serverip Using DPMAC3@xgmii device host 192.168.2.1 is alive Load the .itb image from TFTP server to DDR memory of the board. => tftp 0xa0000000 <itb_file_name> For example: => tftp 0xa0000000 sdk2004_ubuntu_lite_LS_arm64.itb Boot the kernel with .itb image as follows: => bootm 0xa0000000#<board_name> For example: => bootm 0xa0000000#lx2160ardb Board boots to Linux prompt. Step 6 – Validate stress package and measure CPU power using sensors Validate if stress and sensors packages have been installed properly. $ which stress ./usr/bin/stress  $ which sensors ./usr/bin/sensors Measure CPU power before applying stress to the cores. $ sensors CPU power before stress Apply stress to CPU cores using the following command. # stress -c <number of cores> -i <number of IO> -m <number of vm> --vm-bytes 128M -t <time in seconds> & For example: The command applies stress for 60 seconds. For more information on stress command, run stress-h command for help. Measure CPU power after applying stress in given time interval. $ sensors

Trusted Firmware for Cortex-A (TF-A) is an implementation of EL3 secure firmware. TF-A replaces PPA in secure firmware role. Note: Please note the steps listed in this topic can only be performed with LSDK 18.12 and newer releases.   To migrate to the TF-A boot flow from the   previous   boot flow (with PPA), you need to compile the TF-A binaries,  bl2_<boot_mode>. pbl   and   fip.bin , and flash these binaries on the specific boot medium on the board. For FlexSPI NOR flash boot, you need to compile the following TF-A binaries. TF-A binary name Components bl2_flexspi_nor.pbl BL2 binary: Platform initialization binary RCW binary for FlexSPI NOR flash fip.bin BL31: Secure runtime firmware BL32: Trusted OS, for example, OPTEE (optional) BL33: U-Boot/UEFI image   Follow these steps to compile and deploy TF-A  binaries ( bl2_flexspi_nor.pbl   and   fip.bin)  in FlexSPI NOR flash. Compile PBL binary from RCW source file Compile U-Boot binary [Optional] Compile OPTEE binary  Compile TF-A binaries   ( bl2_flexspi_nor.pbl  and  fip.bin)  for FlexSPI NOR flash Program TF-A binaries to FlexSPI NOR flash Step 1: Compile RCW binary  You need to compile the RCW binary to build the bl2_flexspi_nor.pbl   binary. Clone the   rcw   repository and compile the RCW binary.   $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/rcw $  cd rcw $  git checkout  -b <new branch name>  <LSDK tag> .  For example,  $  git checkout  -b LSDK-20.04  LSDK-20.04   Compile the RCW binary for Rev 1 or Rev 2 board. For LX2160ARDB Rev 1: $ cd lx2160ardb For LX2160ARDB Rev 2:  $ cd lx2160ardb_rev2 If required, make changes to the rcw files. $ make   The compiled PBL binary for FlexSPI NOR flash on  LX2160ARDB  for core frequency 2000 MHz, platform frequency 700 MHz and DDR memory data rate 2900 MT/s, with serdes1 = 19 serdes2 = 5 serdes3 = 2,  rcw_2000_700_2900_19_5_2.bin is available at: rcw/lx2160ardb/XGGFF_PP_HHHH_RR_19_5_2 (For LX2160ARDB Rev 1) rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2 (For LX2160ARDB Rev 2) Note:  See the  rcw/lx2160ardb/README  or rcw/lx2160ardb_rev2/README file for an explanation of the naming convention for the directories that contain the RCW source and binary files. Step 2: Compile U-Boot binary You need to compile the  u-boot.bin   binary to build the  fip.bin   binary. Clone the  u-boot   repository  and compile the U-Boot binary for TF-A. $ git clone  https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot.git $  c d  u-boot $  git checkout  -b <new branch name>  LSDK-<LSDK version> .   For example,   $   git checkout  -b LSDK-20.04  LSDK-20.04   $ export  ARCH=arm64 $ export CROSS_COMPILE= aarch64-linux-gnu- $ make  distclean $  make lx2160ardb_tfa_defconfig $ make Note:  If the  make  command shows the error   "*** Your GCC is older than 6.0 and is not supported" , ensure that you are using Ubuntu 18.04 64-bit version for building LSDK 18.12 and above U-Boot binary.  The compiled U-Boot image,  u-boot .bin , is available at   u-boot / . Step 3: [Optional]  Compile OP-TEE binary You need to compile the   tee.bin   binary to build fip.bin   with OPTEE.

Trusted Firmware for Cortex-A (TF-A) is an implementation of EL3 secure firmware. TF-A replaces PPA in secure firmware role. Note: Please note the steps listed in this topic can only be performed with LSDK 18.12 and newer releases.                                                                 To migrate to the TF-A boot flow from the previous boot flow (with PPA), you need to compile the TF-A binaries,  bl2_<boot_mode>. pbl and fip.bin , and flash these binaries on the specific boot medium on the board. For SD/eMMC boot, you need to compile the following TF-A binaries. TF-A binary name Components bl2_sd.pbl/bl2_emmc.pbl BL2 binary: Platform initialization binary RCW binary for SD/emmc boot  fip.bin BL31: Secure runtime firmware BL32: Trusted OS, for example, OPTEE (optional) BL33: U-Boot/UEFI image   Follow these steps to compile and deploy TF-A  binaries ( bl2_sd. pbl/bl2_emmc.pbl   and   fip.bin)  on the SD/eMMC card. Compile RCW binary Compile U-Boot binary [Optional] Compile OPTEE binary  Compile TF-A binaries ( bl2_sd. pbl/bl2_emmc.pbl   and   fip.bin)  for SD/eMMC boot Program TF-A binaries to the SD/eMMC card Step 1: Compile RCW binary You need to compile the RCW   binary to build the bl2_sd.pbl/bl2_emmc.pbl binary. Clone the   rcw  repository and compile the RCW binary.   $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/rcw $  cd rcw $  git checkout  -b <new branch name>  <LSDK tag> .  For example,  $     git checkout  -b LSDK-20.04  LSDK-20.04 Compile RCW for Rev 1 or Rev 2 board. For LX2160ARDB Rev1: $ cd lx2160ardb For LX2160ARDB Rev2: $ cd lx2160ardb_rev2 If required, make changes to the rcw files. $ make The compiled RCW binary for SD/eMMC boot on  LX2160ARDB  for core frequency 2000 MHz, platform frequency 700 MHz and DDR memory data rate 2900 MT/s, with serdes1 = 19 serdes2 = 5 serdes3 = 2, rcw_2000_700_2900_19_5_2.bin   is available at: rcw/lx2160ardb/XGGFF_PP_HHHH_RR_19_5_2 (For LX2160ARDB Rev 1) rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2 (For LX2160ARDB Rev 2) Note: See the  rcw/lx2160ardb/README  or rcw/lx2160ardb_rev2/README  file for an explanation of the naming convention for the directories that contain the RCW source and binary files. Step 2: Compile U-Boot binary You need to compile the u-boot.bin binary to build the  fip.bin binary. Clone the  u-boot   repository and compile the U-Boot binary for TF-A. $   git clone  https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot.git $  cd  u-boot $   git checkout  -b <new branch name>  LSDK-<LSDK version> .   For example,   $  git checkout  -b LSDK-20.04  LSDK-20.04   $ export  ARCH=arm64 $ export CROSS_COMPILE= aarch64-linux-gnu- $   make  distclean $  make lx2160ardb_tfa_defconfig $ make Note: If the  make  command shows the error   "*** Your GCC is older than 6.0 and is not supported" , ensure that you are using Ubuntu 18.04 64-bit version for building the LSDK 18.12 and above U-Boot binary.              The compiled U-Boot binary,  u-boot .bin , is available at   u-boot / . Step 3: [Optional] Compile OPTEE binary  You need to compile the tee.bin binary to build fip.bin  with OPTEE. However, OPTEE is optional, you can skip the procedure to compile OPTEE i f you want to build the FIP binary without OPTEE. Clone the optee_os repository and build the OPTEE binary.  $   git clone https://source.codeaurora.org/external/qoriq/qoriq-components/optee_os $   cd optee_os $ git checkout  -b <new branch name>  LSDK-<LSDK version> .   For example,   $  git checkout  -b LSDK-20.04  LSDK-20.04 $ export  ARCH=arm $   export CROSS_COMPILE=aarch64-linux-gnu- $ make CFG_ARM64_core=y PLATFORM=ls-lx2160ardb $ aarch64-linux-gnu-objcopy -v -O binary out/arm-plat-ls/core/tee.elf out/arm-plat-ls/core/tee.bin The compiled OPTEE image, tee.bin , is available at  optee_os/out/arm-plat-ls/core/. Step 4: Compile TF-A binaries for SD/eMMC boot Clone the atf repository and compile the TF-A binaries,  bl2_sd. pbl/bl2_emmc.pbl   and   fip.bin . $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/atf $ cd atf $  git checkout  -b <new branch name>  LSDK-<LSDK version> .   For example,   $   git checkout  -b LSDK-20.04  LSDK-20.04 $ export ARCH=arm64 $ export CROSS_COMPILE=aarch64-linux-gnu- Build BL2 binary with OPTEE. For SD boot: $ make PLAT=lx2160ardb bl2 SPD=opteed BOOT_MODE=sd BL32= <path_to_optee_binary>/ tee.bin pbl RCW= <path_to_rcw_binary> / rcw_2000_700_2900_19_5_2.bin For eMMC boot:  $ make PLAT=lx2160ardb bl2 SPD=opteed BOOT_MODE=emmc BL32= <path_to_optee_binary>/ tee.bin pbl RCW= <path_to_rcw_binary> / rcw_2000_700_2900_19_5_2.bin   The compiled BL2 images,  bl2.bin and bl2_sd.pbl/bl2_emmc.pbl  are available at atf/build/lx2160ardb/release/ . For any update in the BL2 source code or RCW binary, the  bl2_sd.pbl/bl2_emmc.pbl  binary needs to be recompiled.   To compile the BL2 binary without OPTEE: For SD boot: $  make PLAT=lx2160ardb bl2  BOOT_MODE=sd pbl RCW= <path_to_rcw_binary>/ rcw_2000_700_2900_19_5_2.bin     For emmc boot: $  make PLAT=lx2160ardb bl2  BOOT_MODE=emmc pbl RCW= <path_to_rcw_binary>/ rcw_2000_700_2900_19_5_2.bin   Build FIP binary with OPTEE and without trusted board boot. $ make PLAT=lx2160ardb fip BL33= <path_to_u-boot_binary> /u-boot.bin SPD=opteed BL32= <path_to_optee_binary> /tee.bin The compiled BL31 and FIP binaries,  bl31.bin ,  fip .bin , are available at  atf/build/lx2160ardb/release/ . For any update in the BL31, BL32, or BL33 binaries, the  fip.bin  binary needs to be recompiled.   To compile the FIP binary without OPTEE and without trusted board boot: For SD boot: $ make PLAT=lx2160ardb fip BOOT_MODE=sd BL33= <path_to_u-boot_binary>/ u-boot.bin   For eMMC boot: $ make PLAT=lx2160ardb fip BOOT_MODE=emmc BL33= <path_to_u-boot_binary>/ u-boot.bin To compile the FIP binary with trusted board boot, refer the read me at <atf repository>/plat/nxp/README.TRUSTED_BOO Step 5: Program TF-A binaries to SD/eMMC card Boot  LX2160ARDB   from FlexSPI. Ensure that the switches are set to boot the board from FlexSPI.  For booting from   FlexSPI: SW1[1:8] = 1111 100X [X is 0 for  FlexSPI NOR  flash0 and X is 1 for  FlexSPI NOR  flash1] SW2[1:8] = 0000 0110 SW3[1:8] = 1111 1100 SW4[1:8] = 1011 1000 Boot from   FlexSPI NOR  flash0:  => qixis_reset For   LX2160ARDB Rev 1 , in boot log, you'll see: Board: LX2160ACE Rev1.0-RDB, Board version: B, boot from FlexSPI DEV#0 For LX2160ARDB Rev 2, in boot log, you'll see: Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from FlexSPI DEV#0 Set up Ethernet connection When board boots up, U-Boot prints a list of enabled Ethernet interfaces.

Follow these steps to update the Linux kernel image and device tree on the eMMC card. NOTE: Below steps are valid for both LX2160ARDB Rev 1.0 and Rev 2.0 revisions. Compiling Linux kernel images and device tree   On Linux host, clone the repository with Linux kernel image and device tree: $git clone https://source.codeaurora.org/external/qoriq/qoriq-components/linux $ cd Linux $ git checkout -b <new branch> <start point> For example, $ git checkout -b LSDK-20.04-V5.4 LSDK-20.04-V5.4 where LSDK-20.04-V5.4 refers to a tag in the format LSDK-<LSDK version>- V<kernel version> $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig lsdk.config If you want to make changes to the device tree, open and edit arch/arm64/boot/dts/freescale/fsl-lx2160a-rdb.dts  You can make changes in the Linux kernel source code also if required. $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- The binary kernel image Image and compressed kernel image Image.gz are in arch/arm64/boot/. The device tree blob fsl-lx2160a-rdb.dtb is in arch/arm64/boot/dts/freescale/. Copying the compiled kernel images and device tree to the eMMC card   Step1: Copy the kernel images and device tree from Linux host machine Ensure the eMMC card available on the reference board. Check DIP switch settings for the desired boot type. Power on the board and let the board boot to LSDK distro prompt. In case LSDK image is not deployed on the storage device on the board, execute the following command under U-Boot prompt to boot the board to TinyDistro. For FlexSPI NOR boot: => run xspi_bootcmd For SD/eMMC boot: => run sd_bootcmd Log in to LSDK distro as root/root or TinyDistro as “root”. Bring up a network interface with Linux host. Dynamic IP address assignment: # udhcpc -i <port name in Tiny/LSDKDistro> Static IP address assignment: # ifconfig <port name in Tiny/LSDKDistro> <IP address> netmask <netmask address> up For example: # ifconfig enp1s0 192.168.2.120 netmask 255.255.255.0 up  Copy the Kernel, Kernel.gz images and device tree blob fsl-lx2160a-rdb.dtb from host machine. # mkdir <destination folder> # scp <user>@<ipaddress>:<file path>/<filename> <destination folder> For example: # mkdir /kernelfiles # scp user1@192.168.2.1:/tftpboot/Image.gz /kernelfiles   Step2: Copy the kernel image and device tree to the eMMC card sudo fdisk -l to list the disks that are accessible on board. Mount the eMMC card partition that contains Linux kernel images and device tree. NOTE: Use the command cat /proc/partitions to see the list of devices, their partitions along with their sizes to make sure that the correct device and partition name have been chosen. The eMMC storage drive in the Linux PC is detected as /dev/sdX, where X is a letter such as a, b, c. Make sure to choose the correct device name, because data on this device will be replaced. If your Linux host machine supports read/write eMMC card directly without an extra eMMC card reader device, the device name of eMMC card is typically mmcblk1. In general, the Linux kernel images and device tree are stored in the second partition of the eMMC device (mmcblk1p2). For detail on storage layout on SD/eMMC/USB/SATA for LSDK images deployment, refer to section "LSDK memory layout and Userland" in Layerscape Software Development Kit User Guide. # sudo mkdir <mount_folder> # sudo mount /dev/sdX <mount_folder>  For example: # sudo mkdir /carddata # sudo mount /dev/mmcblk1p2 /carddata Replace Image, Image.gz, and fsl-lx2160a-rdb.dtb on the eMMC card with the new files copied in <destination folder> in the steps above. # sudo cp <destination folder>/Image <destination folder>/Image.gz <destination folder>/fsl-lx2160a-rdb.dtb <mount_location> For example: # sudo cp /kernelfiles/Image /kernelfiles/Image.gz /kernelfiles/fsl-lx2160a-rdb.dtb /carddata Unmount the card. for example: # sudo umount /dev/mmc1blk1p2 Reboot the board. At U-Boot prompt, run the following command to boot the board to LSDK distro using eMMC card. => run bootcmd_mmc1 If U-Boot does not find LSDK on the eMMC card, it will boot  TinyDistro from lsdk_linux_arm64_ tiny.itb  stored on the eMMC card.    

Follow these steps to update the Linux kernel image and device tree for LX2160ARDB on an SD card.  NOTE: Below steps are valid for both LX2160ARDB Rev 1.0 and Rev 2.0 revisions. STEP 1: Compiling Linux kernel images and device tree On Linux host, clone the repository with Linux kernel image and device tree: $ git clone  https://source.codeaurora.org/external/qoriq/qoriq-components/linux $ cd linux $ git checkout -b <new branch> <start point> For example, $  git checkout -b LSDK-20.04-V5.4 LSDK- 20.04-V5.4 where LSDK-20.04-V5.4 refers to a tag in the format  LSDK-<LSDK version>-V<kernel version> $   make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig lsdk.config If you want to make changes to the device tree, open and edit arch/arm64/boot/dts/freescale/fsl-lx2160a-rdb.dts $   make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- The binary kernel image Image  and compressed kernel image Image.gz  are in arch/arm64/boot/ . The device tree blob fsl-lx2160a-rdb .dtb   is in arch/arm64/boot/dts/freescale/ . STEP2: Copying the compiled kernel images and device tree to the SD card   Plug the SD card into the Linux host machine. sudo fdisk -l to list the disks that are accessible to the computer . Mount the SD card partition that contains Linux kernel images and device tree. sudo mkdir <mount_location> sudo mount /dev/sdX <mount_location> For example: $ sudo mkdir /carddata $ sudo mount /dev/mmcblk0p2 /carddata   NOTE: Use the command cat /proc/partitions to see the list of devices, their partitions along with their sizes to make sure that the correct device and partition name have been chosen. The eMMC storage drive in the Linux PC is detected as /dev/sdX, where X is a letter such as a, b, c. Make sure to choose the correct device name, because data on this device will be replaced. If your Linux host machine supports read/write SD card directly without an extra SD card reader device, the device name of SD card is typically mmcblk0. In general, the Linux kernel images and device tree are stored in the second partition of the SD device (mmcblk0p2). For detail on storage layout on SD/eMMC/USB/SATA for LSDK images deployment, refer to section "LSDK memory layout and Userland" in Layerscape Software Development Kit User Guide. Replace Image , Image.gz , and  fsl-lx2160a-rdb.dtb  on the SD card with the new files compiled in the steps above. $ sudo cp /linux/arch/arm64/boot/Image /linux/arch/arm64/boot/Image.gz /linux/arch/arm64/boot/dts/freescale/fsl-lx2160a-rdb.dtb <mount_location> For example:  $sudo cp /linux/arch/arm64/boot/Image /linux/arch/arm64/boot/Image.gz /linux/arch/arm64/boot/dts/freescale/fsl-lx2160a-rdb.dtb /carddata Unmount the card. For example: sudo umount /dev/mmcblk0p2 Plug the SD card into LX2160ARDB and boot the board. At U-Boot, run the following command to boot the board to LSDK distro using the SD card. => run bootcmd_mmc0 If U-Boot does not find LSDK on the SD card, it will boot   TinyDistro from  lsdk_linux_arm64_ tiny.itb  stored on the SD card.

In the U-Boot log, the names of the Ethernet interfaces are printed in the format <name>@<interface type> , for example, DPMAC3@xgmii . DPMAC is a DPAA2 object that identifies the physical interface.    Interface name is not fixed in LX2160ARDB, depending upon which interface is active, name will be assigned  in TinyDistro as well as in Ubuntu distribution. Interface names can be checked using ls-listni command. root@TinyDistro:~# ls-listni dprc.1/dpni.1 (interface: eth0, end point: dpmac.2) dprc.1/dpni.0 (interface: eth1, end point: dpmac.17)   For details regarding creation of a DPAA2 network interface (DPNI) in Linux, see "LSDK Quick Start Guide for LX2160ARDB -> Bringing up DPAA2 network interfaces" in Layerscape Software Development Kit User Guide.   The table below shows the mapping of Ethernet port names appearing on the chassis front panel with the port names in U-Boot and Linux for LX2160ARDB.    Port name on chassis Port name in U-Boot Port name in Linux (tinyDistro) Port name in Linux (Ubuntu userland) Description 40G MAC2 DPMAC2@xlaui4 Interface name will be ethn, for example eth0, eth1. Eth0: If PCIe is connected, else it is any connected DPAA2 interface. PCIe: enp1s0   DPAA: ethx 40G MAC2 QSFP+ port 10G MAC3 DPMAC3@xgmii 10G MAC3 USXGMII port 10G MAC4 DPMAC4@xgmii 10G MAC4 USXGMII port 25G MAC5 DPMAC5@25g-aui 25G MAC5 SFP port 25G MAC6 DPMAC6@25g-aui 25G MAC6 SFP port 1G MAC17 DPMAC17@rgmii-id 1G MAC17 RGMII port 1G MAC18 DPMAC18@rgmii-id 1G MAC18 RGMII port  

On successful probing of the DSA Felix switch, each available front panel switch port should have a network device interface attached with the swpX name format. The ip link show command uses the swpX@enoY name format to also indicate the associated master Ethernet interface for the DSA switch port, which corresponds to an internal ENETC interface, usually the eno2 (Port2) for the LS1028A SoC.
