AM62A7: Methods and tools for quickly batch programming eMMC

AM62A7: How to quickly perform eMMC programming?

Tool/software:

Dear  TI expert

I am currently using the AM62A7 SoC and have a few questions regarding eMMC programming:

  1. I followed the method linked here: TI DFU Flashing Guide to program via DFU. The filesystem size is 100MB, and it takes about 5 minutes to flash. Is this duration normal?

  2. Is it possible to update the eMMC internally by inserting an SD card, and can we also use the SD card to program the eMMC? Are there any tools or methods available for this?

  3. If we have a large number of boards that need eMMC programming, is there a quicker method to flash the program into eMMC? The DFU method seems to take too long.

Thank you for your assistance!

Best regards,
Kangbai Li

    It is possible that the DFU flashing takes a long time if the file is large.

    Let me check if we have anything for this.

    We want to know if it's possible to burn the program into eMMC simply by inserting an SD card, without requiring any command input. This task is handled by our factory workers, who are not technically savvy.

    hello KangBai

        I think this can be done with following steps:

           1. create a bootable sd card and boot to Linux

           2. after enter Linux, automatically trigger a script to copy relative image to emmc card.

           3. after copying the image, reboot the system and change the boot mode to emmc mode

    ---------------------------------------

        you can find the emmc card partition with Linux command

    root@am62pxx-evm:/run# sudo lsblk
