Hello

I installed LineageOs 22.2 (Android 15) and now i’d like to revert to Armbian or Coreelec. Unfortunatelly the M5 can’t boot any more on SDCard. I tried the method with sw3, sw4 button and adb reboot update but, no boot on SDCard. Any idea ?

You can refer to this document to erase the eMMC.

The BPI-M5’s eMMC has higher boot priority than the SD card. If the eMMC contains an image file, it cannot boot from the SD card.
