Hi Tim,
Could you tell me where exactly to get the "xuartlite_serial.c" ?
I could not find "xuartlite_serial.c" in the drivers folder generated by EDK
.
(\ppc405_0\libsrc\linux_mvl31_v1_01_b\linux\drivers\char\xilinx_uartlite)
Look forward to hearing from you.
Thanks,
Tai

This code is...
unsigned int XUartLite_Send(XUartLite *InstancePtr, u8 *DataBufferPtr,
unsigned int NumBytes)
{
unsigned int BytesSent;
u32 StatusRegister;
/*
* Assert validates the input arguments
*/
XASSERT_NONVOID(InstancePtr != NULL);
XASSERT_NONVOID(DataBufferPtr != NULL);
XASSERT_NONVOID(InstancePtr->IsReady == XCOMPONENT_IS_READY);
XASSERT_NONVOID(((signed)NumBytes) >= 0); // Line 195
There's a patch against the file xuartlite_serial.c to fix a problem
where a backlog of bytes causes NumBytes to be a negative number.
Grab the latest xuartlite_serial.c file from your EDK distribution.
Tim
