Ethernet

Added by Anonymous over 5 years ago

Hi,

How can I configure the FPGA such that the ethernet will still be functioning after I program it. I notice that the ethernet is down after I load the fpga.

Cheers,

Jac

RE: Ethernet Rev B - Added by Anonymous over 5 years ago

Hi,

I just received your rev B module. We noticed that the ethernet doesn't work on this revision at all. Is there another way to transfer my fpga and programming file to the linux OS. uBoot will do the FPGA but will it take care of my software file as well?

Thanks!

Hi Jack,

Follow these steps to correct the ethernet:

1. Break into u-boot by resetting the system and hitting any key before the intial countdown finishes.
2. Type the following command:

setenv initphy "gpio clear 28; gpio set 28; sleep 1" 

3. Type the following command:
saveenv

4. Power cycle the board and allow it to boot as normal.

You should now have working ethernet.

Let us know if you have any issues.

Thanks,
\Greg

Greg,

Only 2 "e"s in setenv, not three... Jack probably knows that, but just to be clear...
