J721EXSOMXEVM: How to Boot MCU2_0 through SBL

Part Number: J721EXSOMXEVM

Tool/software:

Hello All.

I have previously built and worked on the R5F cores present in the MCU Domain i.e., mcu1_0.

I want to boot and run my baremetal application on the R5F present in the Main Domain i.e., mcu2_0, mcu2_1, mcu3_0, mcu3_1.

How do I create SBL for MCU2_0? I tried make BOARD=j721e_evm CORE=mcu2_0 in /<pdk_path>/packages/ti/boot/sbl/build but only sbl_uart_img_mcu1_0_release.tiimage was created but no MCU2_0 image was created.

Please guide.

Thank you!

BR

    Hello All.
    I was able to run my app on the MCU2_0.
    There is no separate SBL needed for booting up the mcu2_0 or any other cores, SBL runs on the MCU R5F Core 0 and boots all other cores.
    For UART prints of Main Domain cores, use the Port 0 of Main UART. 

    Sorry for the inconvenience!!!

    Thank you.

    Yes you are correct.

    I think your issue is sorted, can I close this thread ?
