You can
- configure a barebox update handler in your board's code
- export it as Android Fastboot gadget on that USB port
- configure the environment so the gadget is active by default
that way the flashing sequence is:
- use imx-usb-load to load the barebox
- use fastboot to flash the barebox persistently
- use fastboot to flash the rootfs
Cheers
Ahmad
