Ethernet on 3C120

Hi, Does anybody manage to make the TSE run under uClinux ? I try what I read on the wiki, but I can't get a ping from or to the dev board (FPGA Dev kit 3c120). Do I have to use the opencore 10/...

Hi Actris,

thank you for your help!

Generic Media Independent Interface device support is selected and also Altera Tripple Speed (EXPERIMENTAL).

No PHY option is selected.

Anyway, the system doesn't boot.

zImage size is:

-rwxr-xr-x 1 fabio fabio 1390589 2010-07-01 10:38 zImage

the system has 64MB of DDR2 RAM, so that shouldn't be the problem here.

Some possible clues are:

1) I have no definitions for the Stratix III board and I'm using the settings for the Cyclone III 3C120 under

Processor type and features --> Platform (Altera CYCLONE III 3C120 Development board support)

I'm not sure this can be the problem, when I don't set ethernet support the system boots indipendent of the board choice (DE2, CycloneIII, ...).

2) The other suspect I have is Marvell-related.

To make it work under interniche tcp/ip, I had to add some code to the libraries to make an additional reset of the Marvell chip. But this should only create problem with the ethernet, not with the boot of the whole system...

Thanks!
