Re: [U-Boot-Users] MPC8540 gigabit ethernet
That was one of the first things we checked. It is now configured exactly the same as the ADS board. Still the same problems.
Thank you for you help.

One tricky thing about that Marvell PHY is the CONFIG pins, which set up a bunch of default values. The u-boot driver resets some of those settings (to make sure that all the supported speed and duplex options are advertised), but there are some settings which the driver doesn't bother to change. If one of those settings is screwed up, then strange things can happen.
So check the sanity of the settings. :)

Hello,
We are having problem getting gigbit ethernet working with u-boot on our board. I suspect that we have a hardware problem but I am double checking to make sure that I am not missing anything.
u-boot with 8540ADS board and gigabit works fine. u-boot with our 8540 board gigabit has checksum errors as seen by etherreal. our 8540 board 100Mbit works fine in all modes.
We are using the same PHY as the 8540ADS (Marvell 88E1011S)
Since 100Megabit works and Gigabit doesn't have I missed a configuration or is this really a hardware problem.

Does the driver report the speed properly? Which version of the kernel are you using? I'm happy to help, though right now it looks very much like a hardware problem. :(
