Hi Marek,
Perform usual test, disable cache (dcache off) .
I tried and result is still the same.
UPD: I did a little trick:
- I started ping from the board side. That made the board listen to incoming packets (calling in infinite loop eth_rx() ).
- Started ping from PC side.
- In this case board receive ICMP packets from PC:
packet received Receive from protocol 0x800 Got IP len=60, v=45 Got ICMP ECHO REQUEST, return 74 bytes
So, ICMP packets are handled by the board, but ARP packets not.
In my understanding it tells me that at least interface on the board side is alive.
I'm now doing some low-level debugging, however I think this is not the best idea. :) Now dw_eth_recv (designware.c) always returns 0 length of the packet.
I was able to tftp an kernel image using mainline U-Boot on my Arria5 board today. However, I wasn't able to dhcp, but I'm not sure if that's the board or my network.
