Follow these steps to update the DPAA2 MC firmware, DPC, and DPL images for the LX2160ARDB on the SD/eMMC card.  Below steps are valid for both LX2160ARDB Rev 1.0 and Rev 2.0 revisions. Compiling MC firmware Clone the qoriq-mc-binary repository. $ git clone https://github.com/NXP/qoriq-mc-binary.git $ cd qoriq-mc-binary/lx2160a/ $ git checkout LSDK-<LSDK version>. For example, $ git checkout LSDK-20.04 The prebuilt MC firmware image, mc_10.20.4_lx2160a.itb, is available at qoriq-mc-binary/lx2160a/. Note: The exact name of the MC firmware image may vary depending on the LSDK release version used.                  Compiling DPC and DPL images Clone the mc-utils repository and compile the DPC and DPL images. $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/mc-utils $ cd mc-utils/ $ git checkout LSDK-<LSDK version>. For example, $ git checkout LSDK-20.04 If required, make changes to the DPC and DPL files. $ make -C config/ The compiled dpc-usxgmii.dtb and dpl-eth.19.dtb images are available at /mc-utils/config/lx2160a/RDB/. Note: The exact name of the DPL and DPC images may vary depending on the LSDK release version used.             SD/eMMC card start block number for MC, DPL, and DPC images Image  SD/eMMC card start block number DPAA2 MC firmware 0x05000 = 20480 DPAA2 DPL  0x06800 = 26624 DPAA2 DPC 0x07000 = 28672   Refer the LSDK firmware and SD card start block number for complete listing of the SD card start block numbers for all LSDK firmware images.    Programming MC, DPC, and DPL images to SD/eMMC card Boot LX2160ARDB from FlexSPI. Ensure that the switches are set to boot the board from FlexSPI. SW1[1:8] = 1111 1000 SW2[1:8] = 0000 0110 SW3[1:8] = 1111 1100 SW4[1:8] = 1011 1000 Boot from FlexSPI NOR flash0: => qixis_reset For example: For LX2160ARDB, in U-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. 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. NOTE: 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 images from TFTP server Flash MC firmware (mc_10.20.4_lx2160a.itb): => tftp 82000000 mc_10.20.4_lx2160a.itb  Flash MC firmware to SD card: => mmc dev 0; mmc write 8200000 5000 <blk_cnt>  Flash MC firmware to eMMC card: => mmc dev 1; mmc write 8200000 5000 <blk_cnt> Here, blk_cnt refers to number of blocks in SD/eMMC card that need to be written as per the file size. For example, when you load mc_10.20.4_lx2160a.itb from the TFTP server, if the bytes transferred is 1092272 (10aab0 hex), then blk_cnt is calculated as "1092272 /512 = 2133 (855 hex)" + "few sectors for rounding up so that last block is not missed". So, if you round up by 10 (A hex) sectors, for this example, mmc write command will be:  => mmc write 82000000 5000 85F Flash DPAA2 DPL image. => tftp 82000000 dpl-eth.19.dtb Flash DPL image to SD card: => mmc dev 0; mmc write 8200000 6800 <blk_cnt>    Flash DPL image to eMMC card: => mmc dev 1; mmc write 8200000 6800 <blk_cnt> Here, blk_cnt refers to number of blocks in SD/eMMC card that need to be written as per the file size. For example, when you load dpl-eth.19.dtb from the TFTP server, if the bytes transferred is 4583 (11e7 hex), then blk_cnt is calculated as "4583/512 = 8 (8 hex)" + "few sectors for rounding up so that last block is not missed". So, if you round up by 18 (12 hex) sectors, for this example, mmc write command will be:  => mmc write 82000000 6800 12 Flash DPAA2 DPC image.    => tftp 82000000 dpc-usxgmii.dtb  Flash DPC image to SD card: => mmc dev 0; mmc write 8200000 7000 <blk_cnt> Flash DPC image to eMMC card: => mmc dev 1; mmc write 8200000 7000 <blk_cnt> Here, blk_cnt refers to number of blocks in SD card that need to be written as per the file size. For example, when you load dpc-usxgmii.dtb from the TFTP server, if the bytes transferred is 736 (2e0 hex), then blk_cnt is calculated as "736/512 = 1 (1 hex)" + "few sectors for rounding up so that last block is not missed". So, if you round up by 11 (B hex) sectors, for this example, mmc write command will be:  => mmc write 82000000 7000 B Boot the board. Boot from SD card: => qixis_reset sd Boot from eMMC card: => qixis_reset emmc LX2160ARDB will boot with updated MC firmware and DPC and DPL images.

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.

In the U-Boot log, the names of the Ethernet interfaces are printed in the format <name>@<interface type>, for example, DPMAC2@xgmii. DPMAC is a DPAA2 object that identifies the physical interface.  For Linux, in TinyDistro as well as in Ubuntu distribution, by default, only one MAC is enabled as a standard Kernel Ethernet Interface. This interface is named eth0 by default (or eth1 if PCI Express network interface card is discovered first). For details regarding creation of a DPAA2 network interface (DPNI) in Linux, see "LSDK Quick Start Guide for LS2088ARDB -> 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 LS2088ARDB.  In Linux, the mapping of Ethernet port names is not strict. The port names are mapped based on the order in which the Ethernet interfaces are created. As an example, consider a DPL file which defines only one DPMAC object, DPMAC3. When Linux starts, if a net device is created using DPMAC3, it will be labeled eth1 (assuming PCIe interface is eth0).

Trusted Firmware for Cortex-A (TF-A) is an implementation of EL3 secure firmware. TF-A replaces PPA in secure firmware role. 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 boot, you need to compile the following TF-A binaries. TF-A binary name Components bl2_sd.pbl BL2 binary: Platform initialization binary RCW binary for SD 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 and fip.bin) on the SD card. Compile PBL binary from RCW source file Compile U-Boot binary [Optional] Compile OPTEE binary  Compile TF-A binaries (bl2_sd.pbl and fip.bin) for SD boot Program TF-A binaries to the SD card Step 1: Compile PBL binary from RCW source file You need to compile the rcw_1600_sdboot.bin binary to build the bl2_sd.pbl binary. Clone the  rcw repository and compile the PBL 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-19.03 LSDK-19.03  $ cd ls1043ardb If required, make changes to the rcw files. $ make   The compiled PBL binary for SD boot on LS1043ARDB, rcw_1600_sdboot.bin, is available at rcw/ls1043ardb/RR_FQPP_1455/.   See the rcw/ls1043ardb/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-19.03 LSDK-19.03  $ export ARCH=arm64 $ export CROSS_COMPILE=aarch64-linux-gnu- $ make distclean $ make ls1043ardb_tfa_defconfig $ make 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 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 if 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-19.03 LSDK-19.03 $ export ARCH=arm $ export CROSS_COMPILE=aarch64-linux-gnu- $ make CFG_ARM64_core=y PLATFORM=ls-ls1043ardb $ 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 boot Clone the atf repository and compile the TF-A binaries, bl2_sd.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-19.03 LSDK-19.03 $ export ARCH=arm64 $ export CROSS_COMPILE=aarch64-linux-gnu- Build BL2 binary with OPTEE. $ make PLAT=ls1043ardb bl2 SPD=opteed BOOT_MODE=sd BL32=<path_to_optee_binary>/tee.bin pbl RCW=<path_to_rcw_binary>/rcw_1600_sdboot.bin The compiled BL2 images, bl2.bin and bl2_sd.pbl are available at atf/build/ls1043ardb/release/. For any update in the BL2 source code or RCW binary, the bl2_sd.pbl binary needs to be recompiled. To compile the BL2 binary without OPTEE: $ make PLAT=ls1043ardb bl2 BOOT_MODE=sd pbl RCW=<path_to_rcw_binary>/rcw_1600_sdboot.bin                  Build FIP binary with OPTEE and without trusted board boot. $ make PLAT=ls1043ardb 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/ls1043ardb/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: $ make PLAT=ls1043ardb fip BOOT_MODE=sd 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_BOOT                               Step 5: Program TF-A binaries to SD card Boot LS1043ARDB from NOR flash. Ensure that the switches are set to boot the board from NOR bank 0. For booting from NOR bank 0, switch settings are as follows: SW3[1:8] = 10110011 SW4[1:8] = 00010010 SW5[1:8] = 10100010 Boot from NOR bank 0: => cpld reset For LS1043ARDB, in boot log, you'll see: Board: LS1043ARDB, boot from vBank 0   Set up Ethernet connection When board boots up, U-Boot prints a list of enabled Ethernet interfaces. FM1@DTSEC1, FM1@DTSEC2, FM1@DTSEC3 [PRIME], FM1@DTSEC4, FM1@DTSEC5 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 LS1043ARDB Ethernet and FMC 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 FM1@DTSEC4 => setenv ethact <name of interface connected to TFTP server> For example: => setenv ethact FM1@DTSEC4 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 FM1@DTSEC4 device host 192.168.1.1 is alive   Load TF-A binaries from the TFTP server For details about the flash image layout for TF-A binaries, refer LSDK memory layout for TF-A boot flow.                               Flash bl2_sd.pbl: => tftp 82000000 bl2_sd.pbl => mmc write 82000000 8 <blk_cnt> Here, blk_cnt refers to number of blocks in SD card that need to be written as per the file size. For example, when you load bl2_sd.pbl from the TFTP server, if the bytes transferred is 82809 (14379 hex), then blk_cnt is calculated as "82809/512 = 161 (A1 hex)" + "few sectors for rounding up so that last block is not missed". So, if you round up by 10 (A hex) sectors, for this example, mmc write command will be: => mmc write 82000000 8 AB Flash fip.bin: => tftp 82000000 fip.bin => mmc write 82000000 800 <blk_cnt> Here, blk_cnt refers to number of blocks in SD card that need to be written as per the file size. For example, when you load fip.bin from the TFTP server, if the bytes transferred is 1077157 (106fa5 hex), then blk_cnt is calculated as "1077157/512 = 2103 (837 hex)" + "few sectors for rounding up so that last block is not missed". So, if you round up by 10 (A hex) sectors, for this example, mmc write command will be: => mmc write 82000000 800 841 Boot from SD card: => cpld reset sd LS1043ARDB will boot with TF-A. In the boot log, you will see: NOTICE: Fixed DDR on board NOTICE: 2 GB DDR4, 32-bit, CL=11, ECC off NOTICE: BL2: v1.5(release):LSDK-19.03 NOTICE: BL2: Built : 14:59:48, May 28 2019 NOTICE: BL31: v1.5(release):LSDK-19.03 NOTICE: BL31: Built : 15:07:21, May 28 2019 NOTICE: Welcome to LS1043 BL31 Phase U-Boot 2018.09 (May 23 2019 - 14:35:16 +0530) SoC: LS1043AE Rev1.1 (0x87920011) Clock Configuration: CPU0(A53):1600 MHz CPU1(A53):1600 MHz CPU2(A53):1600 MHz CPU3(A53):1600 MHz Bus: 400 MHz DDR: 1600 MT/s FMAN: 500 MHz Reset Configuration Word (RCW): 00000000: 08100010 0a000000 00000000 00000000 00000010: 14550002 80004012 60040000 c1002000 00000020: 00000000 00000000 00000000 00038800 00000030: 00000000 00001100 00000096 00000001 Model: LS1043A RDB Board Board: LS1043ARDB, boot from SD

In Linux, only one MAC is created by default as a standard kernel Ethernet interface. This interface is named eth0 by default (or eth1 if PCI Express network interface card is discovered first). The following figure shows the Ethernet port (ETH8) that eth0 (or eth1) corresponds to, on LS1088ARDB.  The following figure shows the Ethernet port (DPMAC5) that eth0 (or eth1) corresponds to, on LS1088ARDB-PB. Only one interface is created by default because in DPAA2, Ethernet ports need not be associated with Linux kernel Ethernet driver instances. For example, Ethernet ports can be assigned as ports on switches or can be allocated to user space. Furthermore, these associations can be made dynamically.  From Linux, you can list the available interfaces using the ifconfig -a command or the ip link command. For example: $ ip link 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000     link/ether 68:05:ca:36:96:6a brd ff:ff:ff:ff:ff:ff 3: sit0@NONE: <NOARP> mtu 1480 qdisc noop qlen 1000     link/sit 0.0.0.0 brd 0.0.0.0 4: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000     link/ether 6e:01:3f:a2:04:b6 brd ff:ff:ff:ff:ff:ff In this example, Linux eth1 corresponds to Ethernet port DPMAC5 (ETH8) on LS1088ARDB. Create network interfaces Check the network interfaces that are currently available using Layerscape script ls-listni. For example: $ ls-listni dprc.1/dpni.0 (interface: eth1, end point: dpmac.5) The default interface DPNI.0 is configured with a minimal set of resources. For example, it can only receive traffic on GPP0 and its intended uses are network boot and low-bandwidth traffic. For fully-featured DPNI objects, dynamic configuration (explained in upcoming steps) is recommended. Optional - Unbind and destroy existing interface.  $ echo dpni.0 > /sys/bus/fsl-mc/drivers/fsl_dpaa2_eth/unbind $ restool dpni destroy dpni.0 dpni.0 is destroyed The restool utility is a Linux user space command that allows DPAA2 objects to be managed (created, destroyed, and queried for status). Add new network interfaces using Layerscape script ls-addni. For example: $ ls-addni dpmac.3 Created interface: eth1 (object:dpni.0, endpoint: dpmac.3) $ ls-addni dpmac.4 Created interface: eth2 (object:dpni.1, endpoint: dpmac.4)   Check that new interfaces are created using the ifconfig -a or ip link command. Enable the newly created interfaces using the ifconfig command For example: ifconfig eth1 192.168.1.23 up ifconfig eth2 192.168.1.24 up Optional - Save current configuration to a Data Path Layout (DPL) file DPL file is used to create DPAA2 entities prior to Linux boot. To save the current configuration to a DPL file, follow the steps below. After creating the custom DPL, you can program it to the boot source (for example, QSPI NOR flash or SD card) so that the configuration is present automatically next time Linux boots. In this case, the existing DPL is replaced with the updated DPL file. Save this custom configuration to a DPL file (.dts format) on the board. $ restool dprc generate-dpl dprc.1 > <my_dpl>.dts Copy the DPL file to the Linux host machine. You can SCP the file from the board to the Linux host machine. Run following command to convert it to the .dtb format. $ dtc -I dts -O dtb <my_dpl>.dts -o <my_dpl>.dtb For steps to program the new DPL file in the QSPI NOR flash or on the SD card, see LS1088ARDB - How to update MC firmware, DPC, and DPL images in QSPI NOR flash or LS1088ARDB/LS1088ARDB-PB - How to update MC firmware, DPC, and DPL images on SD card.

This how-to topic is applicable for only LSDK 18.09 and older releases. Follow these steps to update the U-Boot binary in QSPI NOR flash.  Prerequisites  Ubuntu 18.04 64-bit should be installed on the Linux host machine for building LSDK 18.06 or LSDK 18.09 U-Boot binary. cpld reset boots the board from QSPI NOR flash0 and cpld reset altbank boots the board from QSPI NOR flash1. sf probe 0:1 means that the alternate bank will be written to. So, if the board boots from QSPI NOR flash0 and sf probe 0:1 is entered at the U-Boot prompt, the commands that follow will program QSPI NOR flash1.   Compiling U-Boot binary Clone the u-boot repository. $ 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>.
