Hi,

Thanks Franck for your response (and for your work on Barebox / Nios 2).

I already change PHY address to 0 (or -1), else, I got an error about unknown PHY id.

We have made some progress.

According to the design, we have to use dedicated memory descriptor. So, I complete in generic.c (well, a copy for this file for the DK board) the description, (tse_mac) with a new entry.

Now, I can see TX LED activity, but, unfortunatly, server don't seems to proceed the Frame (maybe the frame is wrong, and dropped).

I enable trace in barebox altera_tse driver. I see several sgdma TX.

First one has status 0xC, and following have 0x1C, until timeout.

I'll try to dump packet, and check if it's correct.

Edit : In MAC Registers about status, aAlignmentErrors increase (when server perform a broadcast ping). Packet dump shows something similare. To be Continue.

Regards,

Christophe
