Hi all,
I'm learning to write driver for Linux, and then install it to Iliad.

I use command make to compile and insmod to install this driver on Ubuntu 8 ok. But now I don't know how to compile this driver for Iliad because when I install the ko file to Iliad, I got error different architecture.
After that I try to compile this driver on crosstool for Iliad, but not sucessful. Is there any one know how to do this? Please help me!
Thank you very much.
