AXI DMA in SG mode can't recive intrruput only with one channel TX and one channel RX.

I'm using  one  AXI DMA in SG mode  with one channel TX and one channel RX   On ZCU102 board vivado 2018.2.1.   But  can't recive intrruput in SDK   xaxidma_example_sg_intr.c.

  • Wait for the transfer to finish     loop    forever

I  don't  know why.

Hi @peterzh2018 ,

The aresetn signal isn't hooked up to your SmartConnect. I am wondering if the AXI DMA SG reads are even able to happen.

Please connect this signal, regenerate your bit stream, import into SDK and re-test.

Regards,

Deanna
