Hey guys,
I got my S1D13513 working on Blackfin. The driver is loading correctly (I think). But when i want to start nano-X i got a kernel-panic! It seems that the driver has a problem with mm/nommu.c. I will now attach the bootlog. Perhaps anyone can help me with this problem, cause I have no experience in driver development.
Regards,
Michael

Change vma->vm_flags
to
vma->vm_flags |= VM_MAYSHARE | VM_SHARED;
and try again.

Very good! The driver is working but I still don't see anything on my display...
But I think that is a Hardwareproblem which i have to fix....
