Hi Kevin,<BR>
<BR>
When the system locks up, does it get stuck in the FifoRecvHandler() routine?<BR>
<BR>
How many bytes are returned from XLlFifo_RxGetLen(&lp->Fifo) in that routine?<BR>
<BR>
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.<BR>
