I've compiled linux 3.7.1 using the config file in arch/arm/config/ (minus IPMI support, for some reason it won't boot when included), and I'm using the Angstrom rootfs. X11 and Matchbox work fine, but I can't get the touchscreen to work. I've made sure that I've compiled all the kernel options to support touchscreen (s3c2410 touchscreen and s3c ADC) but I don't get a touchscreen in /dev/input/ or /sys/class/input, just the GPIO buttons. I'm sure this has been solved before, has anyone got any insight?
No touchscreen Mini2440 linux 3.7.1
On 2nd thought: Graphics support -> Console display driver support -> <*> Framebuffer Console support -> [*] Map the console to the primary display device -> [*] Select compiled in fonts -> [*] VGA 8*8 font
There are many patches applied to the mainline kernel, possibly even 3.7.1, to get the mini2440 fully functional. I would suggest going to this page: http://www.ptxdist.org/oselas/bsp/pengutronix/mini2440_bsp_en.html download and extract OSELAS.BSP-Pengutronix-Mini2440-2012.12.0.tgz and search around for patch files. Most of them revolve around the touchscreen and the ADC. Good luck!
