AM623: How to make bootloader boot into USB Peripheral boot mode (USB DFU) while boot switch in eMMC boot mode

Yoong Chean Ooi

Part Number: AM623


Tool/software:

Currently, I will need to manually change the boot mode switch to the USB peripheral before I can start flashing the image into eMMC partition. After that, I need to change the boot switch back to eMMC and boot up again.

As part of the automation test, we would like to perform auto-flashing in USB DFU mode and automatically boot into eMMC after the flashing is completed.

Therefore, I would like to clarify if there is any approach for the bootloader to boot into the USB DFU mode for flashing while the boot switch is in the eMMC boot?

Thanks.
