Multiple Ethernet witch Multiple DMA cause a INT error

Hello everyone, I’m trying to add 2 additional Ethernet ports to a custom ZC702 system,my project’s block just like the diagram as below:

                                               2pl_block.png

and then,

the linux kernel version I used was download from https://github.com/Xilinx/linux-xlnx

the driver is  axienet_emac

but it would report the "DMA Rx error 0x14409" when I startup one eth port alternatively.

                                                                     interrupt error.jpg

I have browsed all related AR#,but can't find a  solution. What should i do?

Re: Multiple Ethernet witch Multiple DMA cause a INT error

Hi :

 

I have received similar error on Zynq 7000

 

net eth1: Current BD is at: 0x2e707940
net eth1: DMA Rx error 0x14409
 
Looks to be similar to above. Any suggestions/advice on how to fix that ?
 
Thanks,
CK
