[Merrii Hummingboard A31 - Is this board supported?]

I figured out the device is: Hynix+H27UBG8T2CTB

I cant find any driver to this device, but I have a running version of OpenWRT running. Is it possible to get the driver (?!?!?)

from the OpenWRT source to the Armbian source?

After Fixing some minor errors, I can boot now.

 

But I can't find the root device:

Gave up waiting for root device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/disk/by-uuid/97a9b7ff-f44a-4313-911d-80497c83b965 does not exist.  Dropping to a shell!
Rebooting automatically due to panic= boot argument

 

My question is: Do you have any Idea what driver is missing? I'm trying enabling all block and sd devices in kernel, but no luck at all..

Hello.

 

I just got the board to play with, but I can't find any specific documentation on how to build a specific image to such board.

After researching on google, foruns, etc. I've found some *mentions* on using the bananapim2 config and build (since they use the same core), but it's not working.

 

Building an image using bananapim2 profile, after power on the device start booting from SD, but shows me: unknow image format and start asking for TFP to find flash.

 

Can you please point me toward some useful information on how to build an Armbian image on such card?

 

Thank you in advance
