Hello, I've just built and installed new Armbian console image on OrangePi PC. I am trying to use the a10disp utility, first of all to get information - info command:

 

sudo a10disp info,

 

but it shows error

 

"kernel sunxi disp driver does not support versioning.

This program requires sunxi display driver 1.0 or higher",

 

while dmesg shows error

 

"disp_ioctl, line 1584:para err in disp_ioctl, cmd = 0x0,screen id = 65536".

 

Please advise what is wrong and how to get correct result. 

You are using wrong utility. This is for A10 & A20. You need to use h3disp utililty for H3 based boards.

I believe you are right, but the utility doesn't appear as A10/A20 specific in this link: http://linux-sunxi.org/Display. And the program is a part of Armbian 5.15 for OrangePi PC. About the h3disp utility - how can I switch framebuffer to 16-bit (RGB565) mode? Thanks in advance.

I have that same dmesg error - do you have any video output?

 

h3disp only alters the /boot/script.bin file using bin2fex / fex2bin and some regex/text editing. I don't think it has framebuffer config options, so you'll have to adjust the fex file directly. Be sure to backup script.bin beforehand.

 

Here are the display options for fex files:

You want fb0_format = 5 (for 16-bit RGB565 mode)

 

EDIT: I should read the posted dates.
