petalinux 2019.1 xilinx_axienet driver kernel panic

[andrea@ross]

Hi,

I'm using the 10G ethernet subsystem, but the axienet driver crashes during petalinux boot. I can read correctly the registers of the IP and the version register is correct.

I have not yet been able to solve the error, but there is one thing that does not convince me in the 10G / 25G device-tree automatically generated by petalinux. In vivado I set 

GT Selection to X0Y2

but in the device tree I get 

xlnx,gt-group-select = "Quad X0Y0";

Hi andrea@ross 

Would you make sure clock and reset tree in your design ?

Also, would you make sure device tree  for clock and reset on xilinx_axienet, too ?

Best regards,

[andrea@ross]

Hi @watari 

I checked the clock and reset tree in the design and they're correct (validation also passes). Inside the ethernet verilog file I found that the C_GT_GROUP_SELECT is set to "Quad X0Y0" even if I put Quad X0Y2 in the "Re-customize IP"
