I have this dev board.

I'm still trying to find a linux distro that works with it well,.

The best image I found so far was an Armbian image posted to rvspace.org.

if anyone has ideas for what to do wtih this board i'd like to talk.

I have the NVME drive working. It need at least a 35W usb C charger to be stable.

Hi Richard,

There's an Ubuntu version that was recently released that can be found here.

Huh? 35W for the Vision 2 board plus NVME? Why do they need so
extremely much power? What components consume the power?

I do not have NVME installed and 20w is absolutely fine. So i assume it is that NVME?

Surely an NVMe SSD should require far less than even a single Watt?

Depending on many variables under performance NVMe drives could eat
~10W. I assume it might be more on PCI Gen 5 drives.

For VF2 you need a USB-PD charger that also supports 12V IIRC. Simply
put 5V 3A (15W) is not enough if NVMe is used with significant load.
