Dear all,

I tried to download kernel 3.3 for lpc313x from this repository :  https://github.com/jonsmirl/lpc31xx and other from : http://gnublin.embedded-projects.net/downloads .
After that, I builed it successfully and booted correct. All thing were good, but I can not control GPIO as manual. I did not see this directory : /sys/class/gpio (although I checked GPIO support and /sys/class/gpio/...(sysfs interface) ).
Same with SPI driver, I also checked SPI support but I did not see any SPI in /dev directory.

Any solution for me, thanks alot.
