The LWMON project uses a frozen version of the Linux kernel code, so we didn't port their board to a more recent kernel version yet. Please see arch/ppc/8xx_io/lwmon_kbd.c in the (old ) linux-2.4 kernel tree. > For interactive use.We have a special keyboard with 80 > keys or so.We plan to code the driver in LINUX.But if > implentmented in u-boot as well,it would be perfect. Then you will probably use something similar to the standard PC keyboard code; feel free to peek into drivers/ps2*.c in the U-Boot sources. > that to test some possibilities.I really cannot > understand RBC823 init process of its keyboard.
