Hi,

I am a Linux and PPC newbie.

I have a PPC440EPx Sequoia Evaluation board that runs on Linux 2.6.21. What I would want to do is to control (write and read values to) its GPIO. Perhaps similar to Turbo C's outputb(0x378,0x01) to write and inportb(0x378) to read. I read the PPC440EPx manual but I find it difficult to understand.

Could anyone show me any tutorial or some sample codes?

Thanks,
Dell
