Hi,

The problem is that OCIDEC does not exactly reflect the CF irq line (it has to be reset by soft). The kernel does not reset it and so waits to detect a new irq forever... Try to pass the CF irq directly to the kernel via avalon.

I added in the Avalon-Wishbone interface an output irq signal to avalon directly connected to the CF irq line:

avalon_irq_o <= intrq_pad_i;

I hope that it can helpy you...

Regards,

Thierry
