[U-Boot-Users] Set manually tsec speed in u-boot 1.2.0

[Frank Prepelica]

Hi Ben,

The ethernet adapter (PCMCIA ethernet card) which is directly connect to the board can be forced in windows to use 100Mbit full duplex, but u-boot still use 1Gbit. It's a Marvell phy, the exact phy description I have not in mind.
The processor is a mpc8313.

We are using a customized board which based on the MPC8313ERDB board.

Nevertheless, is there a special env variable to set in U-Boot to use another speed, in this case 100Mbit? (e.g. I can choose by setting "using ethact TSEC1 which tsec should be used) Is there something equivalent for using tsec speed?

Regards,
Frank

How does Windows fit into this?  Are you booting Windows on the board?  
Are you connecting to a Windows machine via a crossover, via a switch, 
or something else?  What PHY is connected to the TSEC?  What processor 
are you using?
