Adeneo QSB Gingerbread Boot on VGA by default

ThomasBandelier — Wed, 29 Jun 2011 11:22:14 GMT

Hi
I can't manage to boot on VGA with latest Adeneo QSB release (4.0).
I managed to use it as second display (video), but when I select it as primary display , android boot process hangs just after loading GL-related libraries.
Has anyone already tried it?
Thanks

Thomas

Hi,

It worked fine for me. I used the following uboot commands to boot into VGA

setenv bootargs_android ${vga}

if it looks like it hanged, i just resarted it at it started working.

What resolution are you using?

HiRemi

I use this config:

setenv bootargs ${bootargs} init=/init androidboot.console=ttymxc0 di1_primary vga => did not work

and as I wanted to use VGA + HDMI (2nd) I tried this one too:

setenv bootargs ${bootargs} init=/init androidboot.console=ttymxc0 di1_primary video==mxcdi0fb:RGB24,1024x768M@60 hdmi

which did not work either

I managed later to use VGA as single screen with:

setenv bootargs ${bootargs} init=/init androidboot.console=ttymxc0 di1_primary video=mxcdi1fb:GBR24,VGA-XGA vga

But I still couldn't find a way to use VGA and hdmi at the same time.

Any clue on that?

Thanks

It seems finally the resolution is too big.

SXGA for primary display does not allow to boot. Memory allocation problem in GL I guess.

Should be fixed by setting a lower resolution.

A good way to have it working is adding

{
    /* VGA 1024x768 65M pixel clk output */
    "VGA-XGA", 60, 1024, 768, 15384,
    160, 24,
    29, 3,
    136, 6,
    0,
    FB_VMODE_NONINTERLACED,
    FB_MODE_IS_DETAILED,},

to the fb modes and set it for di1_primary.
