Hi Kevin, When the system locks up, does it get stuck in the FifoRecvHandler() routine?
How many bytes are returned from XLlFifo_RxGetLen(&lp->Fifo) in that routine? You can try calling XLlFifo_Reset(&lp->Fifo); to see if that clears the fifo. Though, I suspect that this wont fix the root cause of the problem you're seeing. - John On Wed, 2008-04-23 at 11:09 -0700, khollan wrote: > Hi, > > I have done some more digging and it seems like whenever the system works > the command XLlFifo_IsRxEmpty(&lp->Fifo)) returns a 1 meaning that the > RxFifo is empty.
