iMX8QM Android Automotive Bootloader Image Issue

[cbl]

Hello,

I built Android Automotive 12.0.0_2.1.0(Linux 5.15.32 BSP) for the iMX8QM platform.

I tried to write the Bootloader image to the SD card with the command "sudo dd if=flash.bin of=/dev/sdb bs=1K seek=1".

When I insert the SD card into the board, I can't see any boot activity in the Debug console.

Then I wrote the "bootloader-imx8qm.img" and "u-boot-imx8qm-mek-uuu.imx" files to the SD card using the same dd command, but I could not see a boot movement in the Debug console.

What bootloader binary do I need to use to see a U-Boot stream in the Debug console?

Also, could you suggest a dd command to write the bootloader image to the SD card?

What should the "seek", "bs" and "count" parameters be for the iMX8QM in the dd command I will use?

Could you please help with these issues?

Best regards,

Efecan

Hello,

You need to erase everything to burn again your sd, The first commends to burn is uboot with bootloader-imx8qm.img" with bs=1K seek=1 but You have to use DDD to burn everything in android.
