Need help install FygoOS on nvme Rock 5T
Hi everyone,
I'm trying to install FygoOS on my Rock 5T directly onto an NVMe SSD, but I'm stuck on a boot issue after several attempts. Here's where I'm at, hoping someone has run into this before.
BOARD: Radxa Rock 5T (RK3588)
FygoOS version: v1.2.0007, image fygoos_PE_arm_1.2.0007_rock-5t_1834.img.gz
What I did:
- Flashed the FygoOS image to a microSD card with balenaEtcher. Booted successfully from the SD card and reached the
fnnas login:prompt. - Wanted to move the install to a 500GB NVMe SSD. Since FygoOS doesn't have Radxa's
rsetuptool, I booted a separate SD card with Radxa's official Debian image just to update the SPI bootloader, then wrote the FygoOS image directly to the NVMe withdd:
bash
gunzip -c fygoos_PE_arm_1.2.0007_rock-5t_1834.img.gz | sudo dd of=/dev/nvme0n1 bs=1M status=progress
Completed with no errors — confirmed both partitions present afterward (BOOT 360M + rootfs 3.1G) via sgdisk -p.
- Booted from NVMe only (SD removed): black screen on HDMI. Blue LED blinks twice per second in a loop (heartbeat-like pattern). No device found on the network — checked the router's client list, tried an
nmapscan, triedhttp://fnnas.local— nothing responds. Ethernet cable confirmed connected. - Mounted the NVMe boot partition to check the boot files (
boot.cmd,fnEnv.txt,u-boot-rockchip-spi.bin, kernel, dtb files...).boot.cmduses dynamic PARTUUIDs so no stale UUID issue.fnEnv.txtlooked normal (correct dtb file referenced for Rock 5T). - Noticed the FygoOS boot partition ships its own
u-boot-rockchip-spi.bin, presumably matched to its custom kernel, different from Radxa's generic SPI bootloader I'd flashed viarsetup. Flashed the FygoOS one directly via SSH
bash
sudo dd if=/mnt/nvme_boot/u-boot-rockchip-spi.bin of=/dev/mtdblock0 bs=4k
Wrote successfully, no errors.
- Rebooted (SD removed): still black screen on HDMI, still no network presence, still the same blue blinking LED.
Current status: Blue LED blinks steadily (heartbeat-like) but there's no HDMI output and nothing shows up on the network. I don't have a UART/serial adapter yet to get real boot logs, so I can't pin down exactly where it's stalling.
Has anyone gotten FygoOS booting from NVMe on the Rock 5T successfully?
Thanks in advance for any help
