Hi,
I am using Leon's cs8900 device driver and am noticing a stalling problem
that I suspect is with the driver, particularly within the initialization of
the cs8900. I have been able to pin point it down to the following:
I set a breakpoint at cs8900if_service via arm-gdb. Then I send a single
ping packet. The breakpoint is reached and my arm7 is halted. I then send a
second ping packet while the processor is halted. The interrupt is asserted
to 3.3V. I unhalt the processor. The interrupt deasserts to 0V, meaning the
interrupt has been processed. I then send a third ping. The breakpoint is
never reached and the interrupt line remains at 0V.
Essentially, if the cs8900 receives an addition packet while a packet is
waiting to be processed by an interrupt handler, the cs8900 stalls.
Is anyone else experiencing this problem?
Cheers,
Chris
