FlexSPI controller is new IP from Microcontroller group and it will replace QSPI in all future SoCs. FlexSPI is superset and superior to QSPI. Most of the feature set of FlexSPI and QSPI are same, but there are few difference related to IO signal width, command set, default LUT programming and Hyperflash support. FlexSPI has AHB and IP bus interface. AHB 64-bit interface and is mainly use for READ and WRITE flash operation whereas IP is 32-bit interface and it supports all flash operation – READ, WRITE, STATUS CHECK, GET PARAMS etc. FlexSPI programs various commands in LUT and these commands sequence are trigger when we do AHB/IP bus READ/WRITE operation. This documents introduces FlexSPI controller, FlexSPI serial NOR driver implementation and FlexSPI serial NAND driver implementation.  1. FlexSPI Controller Introdunction 1.1 FlexSPI Connections 1.2 FlexSPI Command Interfaces 1.3 FlexSPI Look Up Table(LUT) 1.4 FlexSPI Command Set (Programmable Sequence Engine)   2.

NXP created eIQ machine learning software for QorIQ Layerscape applications processors, a set of ML tools which allows developing and deploying ML applications on the QorIQ Layerscape family of devices. OpenCV is an open-source computer vision library. It offers a unitary solution for both the neural network inference (DNN module) and the standard machine learning algorithms (ML module). It includes many computer vision functions, making it easier to build complex machine learning applications in a short amount of time and without being dependent on other libraries. This document describe applications YOLO object detection, Image segmentation, Image colorization, Image classification, Human pose estimation and Text detection developed based on OpenCV DNN framework.

NXP provides support for a variety of embedded and server Linux distros in addition to the Layerscape components and hybrid Ubuntu support. NXP works together with various open-source communities like Yocto project, OpenWRT, ONIE/ONL, and OpenIL to ensure that support for NXP's platforms is available as part of the regular releases from these distro communities.    This section lists brief how-tos for Layerscape SDK (LSDK) to help you modify/update individual LSDK components such as, U-Boot, Linux kernel, DPL, DPC, on a reference design board when booting the board from a specific boot source, such as QSPI or SD. For example, these how-tos can be helpful if you wish to program a customized Linux kernel image on an SD card.   The section also provides basic Ethernet network interface information, such as Ethernet port mapping (Ethernet port names in U-Boot and Linux) and steps to create Ethernet interfaces in Linux.   LSDK - How-to topics   Booting medium How to topic All QorIQ Reference Design Boards NA LSDK memory layout for TF-A boot flow NA Flash layout for boot flow with PPA – LSDK 18.09 and older releases NA new How to measure temperature of CPU and stress individual cores of CPU NA new How to measure power using sensors and stress individual cores NA  new How to extract kernel, rootfs, and dtb images from Linux ITB image NA new How to customize LITB image from LSDK NA new How to dynamically adjust MC log level using restool NA new How to boot Layerscape board using an empty DPL file NA new How to display MC log buffer in U-Boot, when MC console is not available NA new How to compile and execute custom applications on a Layerscape board  NA How to modify content of the existing rootfs?  LS2088ARDB NA LS2088ARDB Ethernet port mapping QSPI flash   How to update MC firmware, DPC, and DPL images in QSPI NOR flash How to deploy TF-A binaries in QSPI NOR flash NOR flash How to deploy TF-A binaries in NOR flash How to update MC firmware, DPC, and DPL images in NOR flash LX2160ARDB NA How to configure a new flash device for a Layerscape board via CodeWarrior for ARMv8 LX2160ARDB Ethernet port mapping FlexSPI NOR flash   How to update MC firmware, DPC, and DPL images in FlexSPI NOR flash How to deploy TF-A binaries in FlexSPI NOR flash FlexSPI NOR flash SD/eMMC How to update composite firmware in FlexSPI NOR Flash and SD/eMMC card using an SD card SD/eMMC How to update Linux kernel and device tree on SD card How to update Linux kernel and device tree on eMMC card How to deploy TF-A binaries on SD/eMMC card How to update MC firmware, DPC, and DPL images on SD/eMMC card LS1043ARDB NA Ethernet and FMC port mapping NOR flash How to deploy TF-A binaries in NOR flash How to update DPAA1 FMan microcode (ucode) image in NOR flash SD card How to deploy TF-A binaries on SD card How to update Linux kernel and device tree on SD card How to update DPAA1 FMan microcode (ucode) image on SD card NAND flash How to deploy TF-A binaries in NAND flash LS1046ARDB NA Ethernet port mapping QSPI flash How to update U-Boot binary in QSPI NOR flash How to update DPAA1 FMan microcode (ucode) image in QSPI NOR flash How to update PBL/RCW binary in QSPI NOR flash How to update composite firmware image in QSPI NOR flash SD card How to update U-Boot binary on SD card How to update PBL/RCW binary on SD card How to update Linux kernel and device tree on SD card How to update DPAA1 FMan microcode (ucode) image on SD card LS1088ARDB/LS1088RDB-PB NA How to create a DPAA2 network interface (DPNI) in Linux Ethernet port mapping QSPI flash How to deploy TF-A binaries in QSPI NOR flash How to update PBL/RCW binary in QSPI NOR flash How to update composite firmware image in QSPI NOR flash How to update U-Boot binary in QSPI NOR flash How to update MC firmware, DPC, and DPL images in QSPI NOR flash SD card How to deploy TF-A binaries on SD card How to update PBL/RCW binary on SD card How to update U-Boot binary on SD card How to update MC firmware, DPC, and DPL images on SD card How to update Linux kernel and device tree on SD card    

The below steps describe how to modify the content of the existing rootfs. Steps are explained using LX2160ARDB board, however, the steps are applicable to all Layerscape devices and boards. Extract and modify contents of cpio.gz archive Generate .itb image Set up Ethernet connection between TFTP server and Layerscape board Boot the Linux kernel using new .itb image Step1: Extract and modify contents of cpio.gz archive Create a temporary directory for extracting the contents of the cpio.gz archive image. For example: mkdir temp_folder.  Extract the contents of the cpio.gz archive in the temporary folder. For example: gunzip -c rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz | sh -c 'cd temp_folder/&& cpio -i' The temporary folder lists the filesystem as follows:  bin boot dev etc home init lib media mnt proc run sbin sys tmp usr var Make changes to the filesystem in the temporary folder. For example: copy a 'HelloWorld' file in the filesystem using the following command: cp <path>/HelloWorld . Repack the filesystem into a new cpio.gz archive. For example: use the following command: sh -c 'cd temp_folder/ && find . | cpio -H newc -o' | gzip -9 > new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz   Step2: Generate .itb image Change the path for new rootfs (new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz) in linux_arm64_LS.its using gedit editor. For example: Change directory to flexbuild_lsdk<version>/configs/linux. gedit linux_arm64_LS.its Update path as follows:  data = /incbin/("../../packages/rfs/initrd/new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz"); Generate .itb image using the following command: For example: flex-builder -i mkitb -r yocto:tiny This generates lsdk2012_yocto_tiny_LS_arm64.itb image. Copy the .itb image to the TFTP server. Step 3 - Set up Ethernet connection between TFTP server and 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 Step4: Boot the Linux kernel using new .itb image Load the .itb image from TFTP server to DDR memory of the board. => tftp 0xa0000000 <itb_file_name> For example: => tftp 0xa0000000 lsdk2012_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. List the filesystem. NXP LSDK tiny 2012 (based on Yocto) TinyLinux login: root root@TinyLinux:~# ls root@TinyLinux:~# cd / root@TinyLinux:/# ls HelloWorld boot etc init media new_rootfs_lsdk2012_yocto_tiny_arm64.cpio.gz root sbin tmp var bin dev home lib mnt proc run sys usr root@TinyLinux:/# You will observe the HelloWorld file available in the filesystem.

Repeat above steps to load firmware_lx2160ardb_rev2_uboot_xspiboot.img and firmware_lx2160ardb_rev2_uboot_emmcboot.img binary image in SD card. For example: Load firmware_lx2160ardb_rev2_uboot_xspiboot.img image in SD card at block no. 150500 and firmware_lx2160ardb_rev2_uboot_emmcboot.img image in SD card at block no. 300500. NOTE: Make sure that you load these images in SD blocks so that the images do not get overwrite. Eject the SD card. Option 2: Using Linux system Download composite firmware image on Linux machine using the following links: For LX2160ARDB Rev1: For SD boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_uboot_sdboot.img For FlexSPI boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_uboot_xspiboot.img For eMMC boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_uboot_emmcboot.img For LX2160ARDB Rev 2: For SD boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_rev2_uboot_sdboot.img For FlexSPI boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_rev2_uboot_xspiboot.img For eMMC boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_rev2_uboot_emmcboot.img Format SD card (optional, required if the card already has some data so to ensure that images have been loaded to card without conflicting with the existing data). Load composite firmware image to SD card. For SD boot: dd if=firmware_lx2160ardb_rev2_uboot_sdboot.img of=/dev/sdb bs=512 seek=8 For FlexSPI boot: dd if=firmware_lx2160ardb_rev2_uboot_xspiboot.img of=/dev/sdb bs=512 seek=150500 For eMMC boot: dd if=firmware_lx2160ardb_rev2_uboot_emmcboot.img of=/dev/sdb bs=512 seek=300500 Eject the SD card. Step 2: Program updated composite firmware in SD card NOTE: Since the updated composite firmware is now available at required block (SD start block no. 😎 in SD card, therefore, you can boot the board using SD card using following steps. Insert the SD card in SD slot of LX2160ARDB. Set switch settings to boot from SD card : SW1[1:4] = 1000  Restart the board. The board boots from updated composite firmware (SD boot) image loaded in the SD card. The U-Boot log displays: Model: NXP Layerscape LX2160ARDB Board Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from SD Step 3: Program updated composite firmware in FlexSPI NOR flash (DEV#0 and DEV#1) Insert the SD card in SD slot of LX2160ARDB. Set switch settings to boot from SD card=> SW1[1:4] = 1000 Restart the board and stop at U-Boot prompt. Load firmware_lx2160ardb_rev2_uboot_xspiboot.img at 0xa0000000 (DDR address) using the following command: => mmc read 0xa0000000 <start_block_number> <block_count> where, <start_block_number> - start block number in SD card where you have loaded the firmware. For example, if you have loaded firmware at SD card block 150500, start_block_number in hex is 24be4 <block_count> - number of blocks in SD card that needs to be read as per the file size. It is calculated as ‘file size /512’ + ‘few sectors for rounding up so that last block is not missed’. If firmware file size is 52158124 (31bdeac hex), block_count is 52158124/512 = 101871 (18DEF hex) + 10 (A hex) = 101881 (18DF9 hex). For example: => mmc read 0xa0000000 24be4 18DF9 Program default FlexSPI NOR flash: =>sf probe 0:0 =>sf update 0xa0000000 0x0 <firmware_lx2160ardb_rev2_uboot_xspiboot.img _filesize_in_hex> For example: => sf update 0xa0000000 0x0 31BDEAC    Program alternate FlexSPI NOR flash: => sf probe 0:1 => sf update 0xa0000000 0x0 <firmware_lx2160ardb_rev2_uboot_xspiboot.img _filesize_in_hex>  Restart the board to boot from FlexSPI NOR flash 0 (DEV#0). Switch settings to boot from DEV#0: SW1[1:8] = 1111 1000 The U-Boot log shows the following message: Model: NXP Layerscape LX2160ARDB Board Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from FlexSPI DEV#0 Restart the board to boot from FlexSPI NOR flash 1 (DEV#1) as well. Switch settings to boot from DEV#1 SW1[1:4] = 1111 1001  The U-Boot log shows the following message: Model: NXP Layerscape LX2160ARDB Board Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from FlexSPI DEV#1 Step 4: Program updated composite firmware in eMMC card Insert the SD card in SD slot of LX2160ARDB. Set switch settings to boot from SD card: SW1[1:4] = 1000 Restart the board and stop at U-Boot prompt. Load firmware_lx2160ardb_rev2_uboot_emmcboot.img at 0xa0000000 (DDR address) using the following command: => mmc dev 0; mmc read 0xa0000000 <start_block_number> <block_count> where, <start_block_number> - start block number in SD card where you have loaded the firmware. For example, if you have loaded firmware at SD card block 300500, start_block_number in hex is 495D4 <block_count> - number of blocks in SD card that needs to be read as per the file size. It is calculated as ‘file size /512’ + ‘few sectors for rounding up so that last block is not missed’. If firmware file size is 52158124 (31bdeac hex), block_count is 52158124/512 = 101871 (18DEF hex) + 10 (A hex) = 101881 (18DF9 hex). For example: => mmc read 0xa000000 495D4 18DF9 Program eMMC card. => mmc dev 1; mmc write 0xa0000000 8 18DF9 Restart the board to boot from eMMC. Set switch settings to boot from eMMC card. SW1[1:8] = 1001 1000 The U-Boot log shows the following message: Model: NXP Layerscape LX2160ARDB Board Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from eMMC

For example: /dts-v1/; / { dpl-version = <0x0000000a>; containers { dprc@1 { compatible = "fsl,dprc"; parent = "none"; options = "DPRC_CFG_OPT_SPAWN_ALLOWED", "DPRC_CFG_OPT_ALLOC_ALLOWED", "DPRC_CFG_OPT_IRQ_CFG_ALLOWED"; objects { obj_set@dpmcp { type = "dpmcp"; ids = <0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xa 0xb 0xc 0xd>; }; }; }; }; objects { dpmcp@1 { compatible = "fsl,dpmcp"; }; dpmcp@2 { compatible = "fsl,dpmcp"; }; dpmcp@3 { compatible = "fsl,dpmcp"; }; dpmcp@4 { compatible = "fsl,dpmcp"; }; dpmcp@5 { compatible = "fsl,dpmcp"; }; dpmcp@6 { compatible = "fsl,dpmcp"; }; dpmcp@7 { compatible = "fsl,dpmcp"; }; dpmcp@8 { compatible = "fsl,dpmcp"; }; dpmcp@9 { compatible = "fsl,dpmcp"; }; dpmcp@10 { compatible = "fsl,dpmcp"; }; dpmcp@11 { compatible = "fsl,dpmcp"; }; dpmcp@12 { compatible = "fsl,dpmcp"; }; dpmcp@13 { compatible = "fsl,dpmcp"; }; dpmcp@14 { compatible = "fsl,dpmcp"; }; dpmcp@15 { compatible = "fsl,dpmcp"; }; dpmcp@16 { compatible = "fsl,dpmcp"; }; dpmcp@17 { compatible = "fsl,dpmcp"; }; dpmcp@18 { compatible = "fsl,dpmcp"; }; dpmcp@19 { compatible = "fsl,dpmcp"; }; }; }; ​ Note: There is no network object capable of receiving Ethernet frames in the DPL file. You can create more dpmcps if the number of objects that will be created dynamically is high. Generate the DPL file using content.dts. dtc -I dts -O dtb -o dpl.dtb content.dts​ Flash the DPL file, dpl.dtb to the alternate bank.  tftp 0x80000000 dpl.dtb; i2c mw 66 50 20;sf probe; sf erase 0x00D00000 +$filesize && sf write 0x80000000 0x00D00000 $filesize​ Boot the board. After the board boots, create a dpmac. (Make sure you create a DPMAC that is valid based on the selected SERDES protocol configured by the RCW). restool dpmac create --mac-id=3​ Probe the dpmac driver. restool dprc assign dprc.1 --object=dpmac.3 --plugged=1​ Create a network interface. ls-addni dpmac.3​ Save contents as content_new.dts. restool dprc generate-dpl dprc.1 > content_new.dts​    

  Note: MCFBA{L/H} that is used to dump the MC log buffer is valid only after the following command is executed: fsl_mc start mc  ${mc_addr} ${dpc_addr} Run the above command first, then MCFBA contents will be valid. To display the MC log buffer in U-Boot for debug purpose, when MC console is not available: Determine the MC firmware base. At the U-Boot prompt, perform md at 0x8340020 (this is MCFBA{L/H}) => md 0x8340020 10 08340020: e0000006 00000027 00060000 00000000 ....'........... 08340030: 00000000 00000000 00000000 00000000 ................ 08340040: 00000000 00000000 00000000 00000000 ................ 08340050: 00000000 00000000 00000000 00000000 ................ The value at 08340024 is the MCFBAH address. In this case, it is 00000027. The value at 08340020 is the MCFBAL address. In this case, it is e0000000. So you can build the MCFBA base address as:  0x27e0000000. Run the following command to start the MC if it is not booted already. run mcinitcmd Dump the log buffer structure at offset 0x01000000 into the MC firmware base 0x27e1000000 (as per the example). md 27e1000000 27e1000000: 4d430100 00000000 01400000 00300000 ..CM......@...0. 27e1000010: 000000b1 00000000 00000000 00000000 ................ 27e1000020: 00000000 00000000 00000000 00000000 ................ 27e1000030: 00000000 00000000 00000000 00000000 ................ 4d430100 = magic number, 400000 = log buffer offset, 00300000 = log buffer length Dump the content of the log buffer. md 27e1400000   The output size can be increased by specifying the number of objects.  md 27e1400000 <num> For example: md 27e1400000 20 In case that the log buffer has more information, you can extend the output of md by replacing 20 with a greater value.          

Prerequisites: The board should be running Linux and connected to terminal console. Note: For log level debug support, the restool version should be LSDK-2003-RC1 or above and MC version should be 10.20.0 or above. To check restool version: $ root@localhost:~# restool -v restool LSDK-20.04 To check MC version: root@localhost:~# restool -m MC firmware version: 10.24.0 For debugging, use the ls-debug script available in the LSDK rootfs. There is no need to create the debug object. ls-debug -h ls-debug options -h, --help ls-debug help information -ts, --timestamp=X Enable/Disable timestamp printing, X is ON or OFF -c, --console=X Enable/Disable printing in UART console, X is ON or OFF -l, --log=X Enable/Disable printing in DDR log, X is ON or OF -u, --uart=X Set UART ID of the console, X = [0 - 4], 0 = OFF -ll, --level=X Set logging level, X = [0 - 5] 0: Global 1: Debug 2: Info 3: Warning 4: Error 5: Critical -m, mem, --memory Dump information about memory modules available dpxy.z Dump information about MC respective object   For example, to enable logging in console with log level INFO: $ ls-debug --log=on --console=on --level=2 dpdbg.0 created DDR log printing ON UART console printing ON Log level set to 2 $ root@localhost:~# ls-debug --memory Memory dumped information available in MC log/console $ root@localhost:~# cat `find /dev/ -name "*mc_console"` [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_get_obj for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dpdbg_open on DPDBG [I, RESMAN] Handling command: dpdbg_dump on DPDBG [I, DPNI] Memory info: [I, DPNI] MC DDR #1 cacheable memory [I, DPNI] Total: 134217728 bytes [I, DPNI] Used: 14802708 bytes [I, DPNI] Free: 119415020 bytes [I, DPNI] MC DDR #1 non-cacheable memory [I, DPNI] Total: 50331648 bytes [I, DPNI] Used: 27680 bytes [I, DPNI] Free: 50303968 bytes [I, DPNI] DMEM1 memory [I, DPNI] Total: 81920 bytes [I, DPNI] Used: 27168 bytes [I, DPNI] Free: 54752 bytes [I, DPNI] DMEM2 memory [I, DPNI] Total: 81920 bytes [I, DPNI] Used: 27168 bytes [I, DPNI] Free: 54752 bytes [I, DPNI] DDR #1 memory [I, DPNI] Total: 1610612736 bytes [I, DPNI] Used: 143163392 bytes [I, DPNI] Free: 1467449344 bytes [I, DPNI] PEB memory [I, DPNI] Total: 2097152 bytes [I, DPNI] Used: 524288 bytes [I, DPNI] Free: 1572864 bytes [I, DPNI] DP-DDR memory [I, DPNI] Total: 4294967296 bytes [I, DPNI] Used: 0 bytes [I, DPNI] Free: 4294967296 bytes [I, RESMAN] Handling command: dpdbg_close on DPDBG [I, RESMAN] Handling command: dprc_close for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_set_irq_mask for DPRC 1 on portal id 0 [I, RESMAN] Handling command: dprc_set_irq_enable for DPRC 1 on portal id 0 root@localhost:~#

This topic shows steps to customize LITB by using a different kernel image instead of the existing kernel image. Browse to the FlexBuild installation directory. Modify the kernel image in linux_arm64_LS.its. $ vi configs/linux/linux_arm64_LS.its Save the changes done in the file.
