Ethernet on 3C120

Hey,

In fact, I don't care about the type of the dev board....

Does anybody manage to use the Marvell PHY 88E1111 with a Altera Triple Speed Ethernet MAC under uClinux ?

Thanks

Ok I have implemented the Opencore 10/100 MAC in my design today, and it doesn't work.

LED are blinking right when I ping the board, counter of data (rx and tx) in ifconfig are well incremented but there are no answer.

Does anybody got a schematic of the Opencore 10/100 MAC with a Marvell PHY 88E1111?

ideas : I am not sure on how to wire Tx_Clk and gtx_clk ....

Regards,

Hello,

i've had the same problem on 3C120 that will be my next working board and for now, don't solve it under uClinux.

For my test i'm working with the 2c35 where eth works out of the box...

What i've seen :

- ping from a PC : Tx and Rx Led OK (+packet count in ifconfig eth0)

- ping from the board (lo or eth0) ping OK, but no leds activity (OK, it use loopback)

- ping a PC from the board : nothing...

i really don't understand, but i'm just "high level software" developper (c/c++,...) not VHDL/verilog...

if you have an idea,

thx, FP

Hi everybody,

Nobody manage to use the ethernet connection on 3c120 dev kit ?

PS: Guru, could you help us ? please...

Maybe this will help, it's part of bdf file of CIII 3c120 with marvell 88e1111

100 mbit only

Hi dim99,

Thanks for you answer. Does the ethernet works on your 3c120 dev kit ? Which driver do you use under uClinux (The TSE SLS, or the TSE Experimental) ?

Yes it works, but now only transmit, a have some problems with receive packet.

I can't enter isr from sgdma.

p.s. i don't use Uclinux )

i have the only PHY+MAC for tx\rx

what is the clk_25khz2 that you enter in tx_clk_to_the_tse_mac ?

is it the clk_25khz1 exactly ?

The RX is work for me but not the tx...

You don't use any OS ?

clk_25khz1 - 25 mhz from eth_pll with phase = 0;

clk_25khz2 - 25 mhz from eth_pll with phase =180.00;

In some articles or on forum i read that it has to be done the differences between the phase, but maybe i'am wrong.

No, i don't use any OS.

So, can you show your pins to TSE?

If your rx works maybe i'am wrong in some moments with rx.

IT WORKS !!!!

Thank you very very much.

Spaciba !!!
