Zynq ethernet loopback

I am trying to configure the zynq 7000 ethernet port for a loopback test.  I have the interface configured so that it works.  I then turn off Tx and RX, set the loopback bit, then enable tx & rx.  I am following the guidance in ug585 TRM WRT bit 11 in net_cfg.  I then transmit a message and then attempt to receive a message.  No data is received.  I think what I need is a full/complete description of the steps necessary to enable loopback.

Hi @jdreil 

You can find the PHY loopback test here:

https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/emacps/examples/xemacps_example_intr_dma.c

Did you try running it through SDK?

 

Best Regards
