[U-Boot-Users] FCC & Linux
Hello, I have U-boot-1.0.2 working on our custom board and the FCC1 is working fine, I can TFTP the linux Kernel and start it. Now, here comes a problem I do not really understand.
U-boot has configured the FCC fine. Why does Linux need to re-configure it, when it tries to do that by means of MII & MDIO it does not find any PHY...and I lose the ethernet port.
I am using MontaVista 3.1 and the 8260ADS LSP as a base for our Linux port.
Thanks in advance for your help!
Cheers // Matias

Linux should not make any assumptions about if or how any devices it wants to use might have been initialized by any boot loader. Good design is to make no such assumptions, and to initialize the device in the Linux driver.
PHY...and I lose the ethernet port.
Then your Linux FEC driver is broken and / or misconfigured.

Well, then ask MontaVista support for help. You are off topic on this mailing list anyway.
