Hi to all
i boot linux c6x on c6678 EVM and i need to use some driver (i'm newbie in linux )
some .c (gpio.c,i2c.c ,...) file exist in linux-c6x/arch/c6x/driver directory and board_evmc6678.c in linux-c6x/arch/c6x/platform
i have some questions:
in /sys/class exist some driver by default
/sys/class # ls -l

drwxr-xr-x 6 root root 0 Nov 30 00:00 vc
drwxr-xr-x 3 root root 0 Nov 30 00:00 vtconsole
Q1: how can i add driver (for example gpio) from user space (without rebuild kernel)
Q2: is it possible use .c , .h file in c6x-uclinux-gcc ? any body can introduce some example and document for this?
thanks
Ebi
