Le Potato has the android/mbox on it from initial setup, trying to switch to CoreELEC. Installed CoreElec on an microSD, works, boots everything, but can’t access the emmc or re-write it. Removed microSD and tried to go into usb mode to erase or reflash emmc. Linux system (almaLinux, intel) sees it in usb-devices, and I was able to run pyamlboot erase-emmc and it said it succeeded, including on HDMI output it claimed the card was wiped. Rebooted and ran pyamlboot ums-emmc, which says it succeeds, but HDMI out shows it trying to boot and access a TFTP server. Linux system never sees it as a drive.
If I reboot the le potato, it comes back up with the MBOX software (7.1.1 so super-old), so the card really wasn’t wiped. I did plug in a usb power supply to the card before running the pyamlboot commands to make sure it wasn’t a power issue.
How can I wipe the emmc and get it loaded up with the CoreELEC build?
BTW - if I install the emmc after the CoreELEC is booted from the microSD, it does not see the /dev/mmcblk0 device at all
