Banana Pi M2U No boot

alcikoper · August 16, 2025 at 10:03 PM

I've tried booting Banana Pi M2 Ultra with LibreELEC-R40.arm-12.2.0-bananapi-m2u.img.gz on a microsd card but it stucks at very first step:

Code

U-Boot SPL 2025.07 (Aug 13 2025 - 23:32:47 +0000)
DRAM: 2048 MiB
Trying to boot from MMC1

Stock Android image on the e-mmc and stock Ubuntu image on another SD card boots fine on the same device.

After this I've tried the older LibreELEC-R40.arm-12.0.2-bananapi-m2u.img.gz image and it proceeds further, shows Libreelec picture

After that I've had other problems but that's probably unrelated to issue above
