Hello,

I have the ide-controller running on my mips-board. My next step will be to get some graphics out of this box. On the board is an onboard graphics chip and according to the specs it is VGA compatible.

I am using the serial-console for debugging and for sending characters to the box. My source tree is based on kernel 2.2.12.

Because the chip is VGA compatible I try to get the VGA16 framebuffer running on the box. After enabling the VGA16 framebuffer I receive the following output:

Starting kswapd v 1.1.1.1

vga16fb: mapped to 0xa00a0000
Console: switching to colour frame buffer device 80x30

It is doing the take_over_console but when I check the output of my VGA-connector there is no signal. Someone an idea how I can debug this???

Has somebody any experience with framebuffers on a mips?

Any hints/links/tips would be welcome,

Thanks for your time,

	Erik
