Hi everybody,
We are developping a custom board which uses a ppc405EP and on which one we'd like to load a linux hardhat.
During the boot process, we're getting error messages about the ethernet PHY. That is really annoying cause we plan to moubnt the file system via nfs. So no ethernet no NFS...
Could someone give us a tip and tell us if the messages displayed before seem to be normal cause we had to modify some part of the kernel in order to get Linux booting.
What those ethernet messages mean? Everythin seems to happen in the "ibm_ocp_enet.c" eand "ibm_ocp_phy.c" filesPlease help....
So here we go ---->>>>>>>>>
