Zybo-20/Zynq :AXI Stream FIFO IP not transmitting

[Eran Zeavi]

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 !

Hi @Eran Zeavi

Could you provide screenshots of the AXI4-Stream FIFO IP's configuration wizard?

Thanks,
