Part Number: TDA4VM-Q1

Tool/software:

Dear Expert,

I am try to test MMCSD Linux boot w/ SBL only.

Ref as below.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/10_00_00_05/exports/docs/pdk_jacinto_10_00_00_27/docs/userguide/jacinto/boot/boot_app.html

I have an bootable SD, it include boot partition and rootfs partition.

Boot partition file list as below.

lateapp1 = multicore_MCU2_0_MCU2_1_stage1.appimage

lateapp2 = multicore_DSPs_MCU3_0_MCU3_1_stage2.appimage

lateapp3 = multicore_MPU1_0_stage3.appimage

But I found boot failed.

MCU Uart log as below.

Do I miss anything?

Need your suggestion.

SDK : ti-processor-sdk-rtos-j721e-evm-10_00_00_05/pdk_jacinto_10_00_00_27

Device type : GP (I already check I use GP type image)

    Hi Gibbs,

    I guess you have missed the 4th and 5th step in the process(ie: building and copying the bootapp step).

    Regards

    Hi, Gokul

    I make a mistake, you are right. 

    It can work for me now.

    Another concept clarification,

    Bacically, lateapp1/2/3 can be my "custoerized application image" for each different Core

    Step as below.

    To stitch multiple .rprc images into a multicore image, execute the following command

    For Linux:
<PDK>/packages/ti/boot/sbl/tools/multicoreImageGen/bin/MulticoreImageGen LE 55 output.appimage  <core_id_1> core_1.rprc <core_id_2> core_2.rprc

    Is it correct ?

    Thank You Very Much.
