Guillaume,

You might try v1.00a of the xps_ll_temac core.  There are a couple of
issues with v1.00b (posted previously on this list) that may (or may
not) be causing the problem you see.

-Rick

Hello Rick,

> Which version of xps_ll_temac are you using, and which version of EDK?
Using xps 9.2.02i, build EDK_lm_SP2.3+0

IP version for the TriMode_MAC_GMII (xps_ll_temac) is 1.00.b. EmacLite
is=20
1.00.a

> Also, do both designs meet timing?
As the software guy here, I have no idea. I've passed the question onto
the=20
electronics guys...

BUT, you put me on the right tracks: looking at the driver versions I=20
started playing with the options you get in the [Configure IP] of the=20
Ethernet Mac drivers. I couldn't get any improvement with the LLTEMAC,
but=20
after I added the buffers to the EmacLite: IT WORKED !

I'm still having trouble mounting an NFS root and ssh'ing into the
target,=20
but I guess that's another issue...
