About a year ago this guy, http://www.hpmuseum.org/forum/thread-1789.html
managed to compile and boot a small elf binary on the HP Prime. The only thing the elf does is writing pixels to the frame buffer and then halting. (LCD is 320x240 at 24bpp) The HP Prime uses a Samsung SoC ( http://system-on-a-chip.specout.com/l/313/Samsung-S3C2416) with with a single 400MHz ARM9 core and a LCD controller with 2D acceleration. Also i read that the JTAG pins are accessible. Now I was thinking. How difficult would it be to port the the bbb kernel to this system? We already know that elf compiled with gcc boots on the system and we know the address of the frame buffer. Only thing missing is how the keyboard interfaces, I have done a fair share of kernel compiles but never any actual kernel development I don't know the first thing about booting/initializing a CPU/MEM/OS. but if someone could figure out that part I'd like to have a go at writing a frame buffer driver for the LCD. What should I read up on to get a grasp on how the kernel initializes the CPU/MEM? Any help would be greatly appreciated.
