I am having problems with the pcmica driver after having included the
interrupt support in the production quality OAL in Win CE 5.0 on
pxa255.
During initialization I receive the following error from the MDD
layer:
PCMCIA!PCIRequestResourcesEx: I/O Resource Manager request for IRQ 43
with Flag 0 IrqFlag failed
I turned on all the debug zones in the OAL, but it does not look like
ResourceRequestEx (that is called right before the error message) is
calling any routines in the OAL. From msdn it looks like this function
allows devices to request exclusive access to sharable resources. The
dwFlags argument that my function pass to ResourceRequestEx is 0.
What can cause ResourceRequestEx to fail? Should it call functions in
my OAL?

Inger
