Hi everyone,
I'm facing an issue with Armbian installation on Rock 5B Plus.
Hardware
Board: Radxa ROCK 5B+ (RK3588)
Storage:
NVMe #1 (system): 256 GB, in M.2 slot 1
NVMe #2 (backup): 128 GB, in M.2 slot 2
Boot: MTD flash + NVMe
Power supply: both POE+ HAT 25W and official power supply 30W
Software
Armbian: 25.11.2 Desktop ubuntu
Kernel: 6.1.115-vendor-rk35xx
Boot configured via armbian-install → “Boot from MTD Flash, system on NVMe”
Initial install steps
Wrote Armbian image to microSD and booted from SD.
Used armbian-install to install: Boot from MTD Flash, system on NVMe #1
Powered off, removed SD, left only NVMe #1 installed.
Board boots fine from SPI+NVMe #1: blue LED, OS comes up, Green LED, everything OK.
Power off the board and plug NVME #2 (preformatted ext4 with gparted and empty, the disk works because I tried the procedure the other way around, using the second disk as the main one)
Power on. Solid blue light, no OS, no HDMI output (I don't have UART)
lsblk -f with microSD plugged:

I've also tried by "forcing" the mount of NMVE #2 by adding it to /etc/fstab of NVME #1 but nothing changes.
Could you please help me understand if this is an issue related to my configuration or could be a bug?
Thanks
