U-Boot display resolution

Hello.

I would like to change display resolution used by U-Boot.

After entering to U-Boot console there is message:
“…auto-detected panel vga-rgb
Display: vga-rgb (640x480)…”

I would like to change it to 800x480 to properly work with the display.
How can I do that?

Best regards.

Hi,

There are two ways you can do this:

  • Set environmental variable ‘panel’ in uboot to wvga-rgb - if they display properties are different than default you might see some artifacts
  • Change in uboot sources the file of your board (colibri_imx6.c) and on the display parameters structure remove the detect_default field from vga-rgb and add it to wvga-rgb. In the meantime, check the display parameters if they are the same as in Linux environment.

Hi.

I’ve tried it with “panel” variable and it looks Ok.

Thx.
