How do I boot ubuntu on this board?

sfxworks

I've had so much trouble.
On linux it always results in com failure. Related to udev?

On windows, the tool takes forever to download. Once downloaded, the upgrade firmware works, but still doesn't boot. If the steps from Download Image are needed, there is NO instruction where to get the files necessary.  https://wiki.t-firefly.com/en/RO ... grade_firmware.html

It should NOT be this hard to flash the device both via the computer and physically hitting the recover button between the small space at the audio jack.

I would like clear instructions on how to switch this device from android to ubuntu.

Update:
Wiping firmware via eraseflash tool BUT updating firmware via Upgrade Disk Tool works. Updating firmware via RKDev tool doesn't.

Also I could never wipe the firmware except from maskrom. If it was in loader, I always had to do try, let it fail, then reconnect the device.

and which one is the minimal image? https://drive.google.com/drive/f ... PJmkuxFB9ylTz10Wt2l

I tried IREFLY-RK3566-ROC-PC_RTLINUX_UBUNTUUBUNTU-GPT-20210714-1024 and I can't even run apt, it has a temp fs, and the mount points are in the bad way.
FIREFLY-RK3566-ROC-PC_UBUNTU18.04-GPT-20210714-1744.7z has a desktop and I don't want that.

Finally got it to work using their latest image in august
