While I have no experience with this board, I have run Linux on our own boards, with MPC750, MPC755, and MPC7400. Note these three can all be obtained in APPROXIMATELY pin-compatible packages, and their architecthres are compatible (the 7400 adds AltiVec; I'm ignoring differences in clock speed, cache size, etc). The MPC8240 is I believe a completely different beast (I've never used one). I used Linux Kernel 2.2.15 from YellowDog, heavily customized to run on our boards. I made no MPC7400-specific changes, however. Note I made no effort at all to optimize it for the 7400 (other than adding the proper l2cr parameter -- yes, your software has to be aware of the hardware platform's details (:-(). I have only 1 board with 7400s, and we are modifying it to try and evaluate SMP architecture.... Tom Roberts tjroberts@lucent.com ** Sent via the linuxppc-embedded mail list.
