PS/2 device driver problem in uClinux

Hi,all

Is there any body has used PS/2 Keyboard and Mouse interface on Nios uClinux.

I set the configuration of uClinux kernel according to the website

www.alterawiki.com/wiki/frame_buffer (http://www.alterawiki.com/wiki/frame_buffer)

However when I boot kernel, the ps/2 device doesn't work.

(The experimental approach is "cat /dev/input/mouse")

If I use the HAL software provided by Altera in NIOS IDE, the PS/2 device can work.

Therefore I don't have any idea about that.

Could you give me some suggestions .

Thank you very much.
