perfstr Posted July 1, 2016 Share Posted July 1, 2016 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. Link to comment Share on other sites More sharing options...
Igor Posted July 2, 2016 Share Posted July 2, 2016 You are using wrong utility. This is for A10 & A20. You need to use h3disp utililty for H3 based boards. Link to comment Share on other sites More sharing options...
perfstr Posted July 2, 2016 Author Share Posted July 2, 2016 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.

whysopi Posted December 7, 2016 Share Posted December 7, 2016 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: http://linux-sunxi.org/Fex_Guide#.5Bdisp_init.5D You want fb0_format = 5 (for 16-bit RGB565 mode) EDIT: I should read the posted dates.
