Hi people,

I have some similar problem:

we are working on ml 506 platform and have problem with Ethernet.When we configure FPGA from SDK with *.bit and *.elf every thing is ok. Ethernet link is established and I can ping platform. Application is simple TCP server based on LwIP with UART used for debugging.  Then we create SystemACE file according to the user guide http://www.xilinx.com/products/boards/ml505/docs/ml505_bsb_std_ip_addition.pdf and copy it to CF. We used CF card to boot ml506,  everything works fine, UART debug messages seems fine, LED diode which indicated link speed is on (we tried all speed 10/100/1000), but when I ping platform there is no response (diode which indicated that packet is received RX blinks but TX never). Based on debug messages It seems that LwIP doesn't recevie packets at all. If we reload the software from SDK (with hardware configured from CF), application starts working! Also, I've tried Web server demo application provided with the board from CF and it works fine. Any ideas what may cause this problem?

Phelix, Have you tried to load my ace file?

Previously I used Xilinx EDK 11.2.

When update to the 11.3 problem was solved. 

genace.tcl from 11.2 have some bags.

Camarada,

I believe that you hit the issue mentioned in this AR

Please upgrade to 11.3.

Felix and Dragan thanks a lot. Problem was solved with 11.3 genace.tcl script.

Hello, dragan, I have the same proble as you. Ping to FPGA have no response. Have you find solution?

[dragan.topalovic]

Yes I have, like I mention in upper discussion. Problem was in genace.tcl script. When I upgrade script to the version 11.3 problem was solved. You should look at jumpers J22, J23 to choose between sgmii or gmii maybe that is problem.

Thx, Dragan. When I used 11.3 tcl script with 11.2 EDK apps without net was working. Now I create ace file on 11.3 EDK and net's working now.

Thank you.
