uclinux and thriple speed ethernet

Altera_Forum · ‎10-18-2009

Hello.

Im trying to get ethernet working on my cyclone3 dev board with uClinux. Im using the sof from the udp offload example at nioswiki.com(http://www.nioswiki.com/exampledesigns/nios2udpoffloadexample) and my own kernel. It boots fine:

From this, it seems that the device drivers works.

I run ifconfig eth0 <addr> and get:

--- Quote Start ---

eth0 up, link speed 100, full duplex, eth hw addr 00:07:ed:0d:09:19

--- Quote End ---

Still seems ok, right?

I have my computer connected to the same switch as the board, and in the same ip range. Now, when i try to ping my computer I get no response but the RX and TX leds on the board lights up. Same thing when I ping the board from the computer; no response but RX-led on board lights up. I also have a dhcp-server running on the computer, but the board cant connect. Apparently, it's incoming traffic to the board that's the problem.

Is it possible that I've configured the kernel wrong? Is there a working kernel.config with ethernet available for this board somewhere?

You can try using wireshark on your pc it will tell you if there are any packets from the nios seen by the PC

Try directly connecting the PC to the eval board using a cross over cable it might be the switch

andurs,

Did you resolve this issue? I am facing a similar problem.

After booting linux I try running dhcpcd and have no luck with that.

>dhcpcd eth0

ATSE: Waiting on PHY link ......

eth0 up, link speed 100, full duplex, eth hw addr 00:07:ed:0d:09:19

After this nios2_terminal is hanging.

Any information would be great!

thanks and regards,

priya

Have you guys tried Altera-TSE(SLS's TSE) rather than atse.c???

I think the example project for the C3 devkit is using Altera-TSE.

Change the menuconfig setting to use this Altera-TSE(SLS).

Also, if you still see the receive LED blink, but not getting packet right, then check the SG-DMA part, especially, IRQ and descriptor is set correctly.

Oh, one more. Not sure which Quartus version you guys are using, but example design was compiled on Q9.0 I believe. You might want to try on 9.0.

thanks nekojiru, i think it's some problem with my hw design. I got another example from SLS corp and that seems to work.

thanks,
