Hello,
Does anyone know if u-boot will work with the SMSC LAN8700 (same interface as LAN8187) Ethernet transceiver? Specifically I am trying to use it with the Atmel AT91SAM9260 microcontroller using MII. I am developing a board similar to the AT91SAM9260-EK evaluation kit and would like to replace the Davicom DM9161a. If u-boot currently doesn't work with the LAN8700 can anyone provide me with a little guidance as to the magnitude of the effort to add this transceiver to u-boot? Sorry if my question is a bit naive, I am a newbie when it comes to u-boot.
Normaly you will have no problem
the LAN8700 is really simple.
Best Regards, J.

Kevin,
We tested 8700 in MII mode, it works OK. - Recompile u-boot to use MII instead of RMII - Swap the pins PA10, PA11 to PA23,PA24 for TX(2:3)
We will be testing that in the kernel(2.6.25) soon, hopefully that will work OK too.
