Hi,
This is regarding EMMC Boot error for SK-AM62 TI Board.
I have successfully verified the SD Card booting for the above mentioned Board with the Prebuilt binaries & Yocto built images.
While attempting the EMMC boot, I am facing the error regarding dfu-utils. Below I have added the boot logs also for the better understanding.
1. Boot Logs are given below:
U-Boot SPL 2021.01-g74fc69c889 (Sep 07 2022 - 18:33:54 +0000)
SYSFW ABI: 3.1 (firmware rev 0x0008 '8.3.2--v08.03.02 (Jolly Jellyfi')
SPL: Unsupported Boot Device!
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
Also for transferring the u-boot image from target to the host, I am facing the error and the command which was used is mentioned below:
2. After giving the following command below error was created:
sudo dfu-util -R -a bootloader -D tiboot3.bin

Resetting USB to switch back to runtime mode
One of the Post of TI forums mentioned the SK-AM62 prebuilt binaries doesn't have the USB DFU function.
1. Can you please tell why the pre-built binaries doesn't have the USB DFU support?
2. Downloaded the yocto source code version of "08.03.00.19"
Please tell the defconfig am62x_evm_a53_defconfig or am62x_evm_r5_usbdfu_defconfig to build the u-boot binaries for the USB DFU boot on the SK-AM62 board.
I tried to find out the solution for this issue on the TI Forum also but not able to resolve it in a proper manner.
Requesting you to kindly guide me to resolve this issue.
Thanks & Regards
