GRUB "no such partition" error on Retroid Pocket 5 with Armbian

[miguelsotobaez]

I am encountering a boot error on my Retroid Pocket 5 when trying to run Armbian.

The error message:

Booting: mmc 0
error: no such partition
grub rescue>

Details:
Image used: Armbian_community_26.2.0-trunk.151_Retroidpocket-rp5_noble_current_6.12.63_gnome_desktop.img.xz

Flashing method: I used the Armbian Imager specifically for the RP5.

Troubleshooting: Other images (like Batocera) boot and work perfectly, so the hardware and SD card seem fine. It appears to be an issue specifically with this Armbian build or the partition table it creates.
