Hi Mike and Mark,
Thanks for your help.
But, I've got a bit of problem again. I have modified for GPIO standard I/F referring other accepted GPIO driver.
According to Documentation/gpio.txt, I tried to create GPIO node like below.
[root@localhost gpio]# ls export gpiochip244 unexport [root@localhost gpio]# echo 1 > export bash: echo: write error: Invalid argument [root@localhost gpio]#
But it fails.
Could you teach me the reason/cause why?
Thanks, Ohtake(OKISemi)
