I just wanted to report that I used crosstool 0.27 successfully (thanks Dan).
I created a gcc3.3.2 / glibc2.3.2 powerpc-405-linux-gnu cross compiler on Redhat 9.0. I've successfully used it to compile linux and U-Boot
binaries for my MPC8540.
However, I had a problem with getting U-Boot to work
with the above toolchain, if the -g and -Os where
turned on. Previously, I was using the Metroworks
toolchain (gcc 2.95) to compile my U-Boot (1.0.1) and
I could create a binary with -g and -Os that worked.
Can someone tell me why I can't use -g and -Os with the gcc3.3.2 /glibc2.3.2 to compile the U-Boot code for MPC8540?
If it's just "it doesn't boot", you might consider divide-and-conquor. e.g. try building just one source file with -Os and see if that works. If it does, then do a binary search to see which source file builds wrong with -Os...
