Hello all,
I start using Olinuxino with all things compiled from scratch. I have kernel,uClibc with builroot and root on NFS for easy development. I start learning some about Fex ,but found that there is problem configuring VGA.

[disp_init]
disp_init_enable = 1
disp_mode = 0         
screen0_output_type = 1
screen0_output_mode = 4
screen1_output_type = 0
screen1_output_mode = 5
fb0_framebuffer_num = 2
fb0_format = 9
fb0_pixel_sequence = 2
fb0_scaler_mode_enable = 0
fb1_framebuffer_num = 2
fb1_format = 9
fb1_pixel_sequence = 2
fb1_scaler_mode_enable = 0

When I put screen0_output_type = 4 (VGA) I get no picture. I must use screen0_output_type = 1 (LCD) to get output working. Have anybody the same experience ?

I'm not sure the A13 can drive VGA natively, but even if it can the Olimex design is for LCD and VGA is derived from that (look at schematic).

Compile your kernel with this configuration https://docs.google.com/file/d/0ByOKWTCf95tua2J4U1BDS3BVSzQ/edit before this commande $ make ARCH=arm a13om_defconfig

Hi Jamouz,
The command make says it does not have a target. Can you help me compile my kernal.
