PROCESSOR-SDK-J721E: SBL eMMC boot failed

Part Number: PROCESSOR-SDK-J721E

Hi Ti,

When we are debugging SBL eMMC BOOT0 startup, tifs.bin and app are obtained from the UDA BOOT partition of EMMC，which dose not match with PDK user guide chapter:  5.2.8.3. Booting Via eMMC BOOT0 partition we confirmed with FAE of TI China, this may be a bug.  Could you confirm that?

On PDK user guide, chapter 5.3. Boot App, it only support OSPI and MMCSD. Is there a plan or a patch we could apply to enable boot app loading image from eMMC?

Thanks

    Are you trying to boot the SBL from boot0 partition and the app and tifs from UDA?
