This won't be any consolation, but it works for me with my hardware and configuration. I'm using ELDK 3, with NFS root, on a P501 board from General Micro. My software revs are: [root at tweety root]# cat /proc/version Linux version 2.4.23-pre9 (root at tweety) (gcc version 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a_2)) #79 Mon Oct 18 14:32:24 EDT 2004 gcc version 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a_2) GNU gdb Yellow Dog Linux (5.2.1-4b_3) root at tweety root]# cat /proc/cpuinfo processor : 0 cpu : 440GP Rev. C revision : 4.129 (pvr 4012 0481) bogomips : 599.65 vendor : GMS machine : P501 The software, except for the kernel I'm running, came off the iso image available on the Denx site. Good luck!
