Flashing EMMC module on Renegade Elite

Installed Debian 12 on my 128 EMMC using the micro sdcard, I need to do a fresh re install on emmc how do I get my Renegade Elite to boot from the sdcard instead of the emmc first so that I can reflash the system? I haven’t found any directions of how do yet.

Boot is controlled by boot_targets variable. You have to stop at the boot prompt and run the following:

env set boot_targets mmc1
