UARTLite with interrupts example code not working

I've already done the PlanAhead -> XPS projects, including and AXI Interrupt Controller between Uartlite IP and PS. Everything works well except the Uartlite interrupt code.

I compile and run with no errors this code, but neither I send anything nor receiving through pins.

I've been Reading the forums but I can't get a solution.

I don't have any suggestions but I've been fighting the same thing or something similar for a week now. I'm working on a Linux platform and the problem appears to be interrupt related. I can see characters get sent and received and the RX FIFO level and status reg bits react appropriately by directly reading and writing the UARTLite registers (RX FIFO, TX FIFO, STATUS and CONTROL). This might be something for you to try to make sure the physical connections are correct. Use "devmem" or "devmem2" in Linux depending on your distro or Xil_In32 / Xil_Out32 in an OS-less system.

back to fighting interrupts....
