[FAQ] PROCESSOR-SDK-J7200: how to use SBL and boot system with rootfs on eMMC

Part Number: PROCESSOR-SDK-J7200
Other Parts Discussed in Thread: DRA821

SBL is used for fast CAN response. 

In the boot_app_mcu_rtos demo: 

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/07_03_00_07/exports/docs/mcusw/mcal_drv/docs/drv_docs/demo_boot_app_mcu_rtos_top.html

The MCU2_0 and MCU2_1 images are from mcusw. And also there isn't much content how to boot with rootfs.

Please share one example for commonly used system boot requirement:

step1: use SBL to boot MCU1_0 image 

step2: MCU1_0 use boot_app demo to boot other cores

step3: additionally to step2, continue A72 boot with rootfs from eMMC

  • Below example is based on DRA821 SDK V7.3, and verified with TI DRA821 EVM .

    verification environment:

    1. DRA821 SDK V7.3

    2. TI DRA821 EVM

    3. A72 runs Linux

    4. MCU1_0 runs boot_app_mcu_rtos demo

    5. MCU2_0 runs app_remoteswitchcfg_server_strip.xer5f

    6. MCU2_1 runs app_remoteswitchcfg_client_strip.xer5f

    7. rootfs : eMMC /dev/mmcblk0p2

    step to build:

    1. build UART flash programmer (please refer to the instructions in the flash_ospi_boot_main_demo.sh)
    2. build cust SBL (please refer to the instruction in the flash_ospi_boot_main_demo.sh)
    3. build MCU1_0 image (please refer to the script: build_boot-app-mcu-rtos_release.sh) 
    4. build ethfw binaries : in $ethfw, run :  make ethfw_all BUILD_SOC_LIST=J7200 PROFILE=debug
    5. run makemulticore_j7200.sh to make multicore image for MCU2_0 and MCU2_1
    6. run constructappimageshlos.sh to make image for stage 2 (ATF, dtb, kernel)

    step to run:

            1. flash rootfs to eMMC

                assume we get a working SD card, which can boot system successfully (SD boot) and ethfw works well.

               Please refer to the instructions to flash the rootfs to eMMC:

               https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j7200/07_03_00_04/exports/docs/j7200/linux/How_to_Guides/Target/How_to_flash_emmc_device.html

           2. flash the binaries to OSPI flash

               change the EVM to UART boot, https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/07_03_00_07/exports/docs/psdk_rtos/docs/user_guide/evm_setup_j7200.html#uart-boot-mode, 

               after booting the board with above configurations, use the script: flash_ospi_boot_main_demo.sh. After successfully flash these images, restart the board to OSPI boot. 

            3. Boot from OSPI

                https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/07_03_00_07/exports/docs/psdk_rtos/docs/user_guide/evm_setup_j7200.html#xspi-boot-mode
