Re: frame buffer

I'm trying to do this way you suggested.
I encoutnered following issues:

1. I can't find mknod. Is there any other way to create a character
device on android?
   I've tried to use mknod from libc but i get "illegal instruction"
message (the same program compiled on linux works and create character
device)

2. How can I check if kernel was compiled with adding module capability?
    I need to create my own fb and so device driver that will push
data from frame buffer into surface flinger.

Thanks,
