once again running into a user problem,
i got myself a running kernel and i had it working with FrameBuffer support before but it stopped working, my old compiled kernel does still work but i cant seem to find out what is wrong in my new .config to get it working again. currently it doesn't display anything on my vga but i have console over uart.
does someone know which settings i need to set specifically to get it working again?
ah found my problem had to enable VGASTATE as well ::)
Hi, ;)
Taking advantage of your question, which required modules to enable VGA ouput?
i set the following modules located under: Device Drivers / Graphics Support
<M> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support
<M> Mali DRM supprt
<M> ARM Mali GPU modules
<M> Lowlevel video output switch control
<*> Support for frame buffer devices -->
<*> Enable Firmware EDID
Display options for sun4i/sun5i --->
<*> DISP Driver Support(sun5i)
-*- Reserve memory block for sunxi/fb
<*> Disable FB/UMP integration
<*> LCD Driver support (sun5i)
[ * ] Backlight & LCD device support --->
<M> Lowlevel LCD controls
<M> Lowlevel Backlight controls
<M> Generic (aka Sharp Corgi) Backlight Driver
Display device support --->
<*> Display panel/monitor support
Console display drive support
<*> Framebuffer Console support
<*> Map the console to the primary display device
[ * ] Bootup Logo --->
[ * ]Standard black and white linux logo
[ * ]Standard 16-color linux logo
[ * ]Standard 224-color linux logo
i haven't tested this over the LCD connector yet, only through VGA.
hope this helps.
Thanks very much. Now, the question is which modules to load? ;D
