Hi leewood,

Wel-come to the club.

I am also looking for same solution, it sound like uclinux issue.

Just check above link by David McCullough

hint: You can add some show_mem(); func call in your driver to see how much memory is free when kernel goes out of memory.

Look for which kind of memory your process required and those page are free or not.

Nios uclinux have only __DMA__ pages........

thanks,
