Part Number: AM62A7

Tool/software:

Hi TI experts:

    As the title describe above, we want to boot our board from eMMC with SBL faclon mode, Our sdk version is 10.0 or 9.2. How to set it? Thanks!

Best regards!

    Hello,

    Please refer to the following SBL_EMMC_LINUX bootloader designed to boot Linux with or without Falcon boot:

    I don't known how to flash kernel and rootfs to the user area of eMMC,the offset is boot0 or user partition?

    The MCU+ SDK supports booting from BOOT0 partition only. So, those are the offsets in the BOOT0 partition.

    If the area of BOOT0 partition isn't enough, is there any solution?

    There is eMMC UDA partition but the MCU+ SDK does not support booting from it at least officially.

    If required, you could modify the following API in the Bootloader MMCSD driver to load the images from the partitions in which they are flashed:

    Hi,Prashant:

        The falcon mode boot from eMMC fail too, although the area of BOOT0 partition is 32MB, the logs show as below. What's focus about the message error?

        After I rebuild the image and flash it again, the log show below, stop at the last line.Attached file is the flash script.

    This is not possible if the eMMC boot partition size is 32MB. The Linux Appimage is of size ~20MB and is flashed at offset 0x1200000 (18MB). So, the leftover space (14MB) would not be enough.

    Is your eMMC boot partition size larger than 32MB?

    Is your eMMC boot partition size larger than 32MB?

    ==>No.  I have changed the offset of related images to make sure the area is enough(examples/drivers/boot/sbl_emmc_multistage/sbl_emmc_stage2/am62ax-sk/r5fss0-0_nortos/example.syscfg), and I don't think that is the root case.

    In the previous threads, you have the SBL Falcon boot working from SD card. Are you using the same working Linux Appimage for eMMC boot as well?

    I would expect you to have everything same except using SBL_EMMC_LINUX_MULTISTAGE instead of the SBL_SD bootloader.

    Yes, Linux Appimage is the same. the follow boot from eMMC is different from SD. Could you have a try on EVM?
