Eran Zeavi Posted July 22, 2022 Share Posted July 22, 2022 Hi, I am working on Zybo-20, trying to run a simple example to stream data from Zynq to the AXI Stream FIFO and back to Zynq The code example I am running on the ARM in StandAlone OS: https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/llfifo/examples/xllfifo_polling_example.c the schematic is in the attachment. The issue is that when sending the data in TxSend, it waits for transmission complete forever in the loop below : /* Check for Transmission completion */ while( !(XLlFifo_IsTxDone(InstancePtr)) ){ } in other words, transmission never succeeds Any good idea is welcome ! Thanks ! Link to comment Share on other sites More sharing options...

Hi, I am working on Zybo-20, trying to run a simple example to stream data from Zynq to the AXI Stream FIFO and back to Zynq
The code example I am running on the ARM in StandAlone OS:
https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/llfifo/examples/xllfifo_polling_example.c
the schematic is in the attachment.
The issue is that when sending the data in TxSend, it waits for transmission complete forever in the loop below :
/* Check for Transmission completion */
while( !(XLlFifo_IsTxDone(InstancePtr)) ){
}
in other words, transmission never succeeds
Any good idea is welcome !
Thanks !
