[U-Boot-Users] Re: U-Boot and 64260 ethernet controller.
Hai Steve
Even we are using a board with 750Cxe and Gt64260 and we are successfully running ethernet and linux
Greetings.
I was curious if anyone had experienced an issue I am having with the ethernets on the Discovery I chip (64260). Essentially, I am bringing up new hardware with U-Boot and I am able to get the ethernets initialized, I can start sending a ping, I see the ARP request go over the wire from my board, I see the ARP reply come back, but my ethernets never get any packets. All I get are a bunch of Rx Resource Errors with no packets received. I should note that a custom and closed source bootloader is already successfully working and booting Linux. I have everything working except for the ethernets. If anyone has some insight, I would be very grateful. I am using a 750 CXe processor with this board. Thanks.

So please tell us what all changes related to ethernet who have done , so that we can help you.

It has been a long time since I used the 260 and a while since the 360. But check your memory window setups. Make sure you have caching off to at least prove transfers, and verify the Rx mappings are correct. I had this working a while ago. It is just a setup problem somewhere in the plethora of memory mapping windows. One thing you can do is stash your Rx and Tx rings into the internal SRAM. At least that removes one area of potential conflict, along with increasing performance once you enabl caching again on main memory.
Thanks Brian
