Hello All,
I need help in flashing and booting any image for BeagleV Ahead using a SD Card.
I have created a script to flash the Ubuntu image onto the SD card, but I am facing issues while trying to boot from it. Initially, I followed the official startup guide and successfully flashed the eMMC. However, the board now always boots from the eMMC, and the OS starts from there.
Could you please guide me on how to force or configure the board to boot from the SD card instead?
This is the output i am getting

Any Idea how to boot through the SD Card?
