Don't waste your time on all the bugs and problems that have been fixed since.

Ummm... What's BCSR4? If PPCBoot initializes it, why do you have to initialize it again? Like Wolfgang said why reinvent the wheel > The device isn't working even when i use ppcboot (i configured ppcboot to > use it). Sic! So get PPCBoot running first. > 1.

Most of this depends on your hardware. We are using the FEC with this kernel version and it is working fine. Get the 2.2.14 kernel from Wolfgang's FTP site if it is still on there the FEC code and lots of other goodies work with this kernel version. Sometimes you cannot upgrade to a new kernel version this is possibly political and not a design decision. Sometime there is also no reason to upgrade to a newer kernel version and have to retest all possible variants of device with the new kernel version.
