I do have FPU emulation enabled in the kernel. I was able to get a Yellow Dog 4.1 root filesystem to work. However when I move up to YellowDog 5.0 or to Fedora 7, I have system lags. (For example, shortly after boot-up, date and top do not behave properly. For example top displays "nan" values. However a few minutes after boot up everything seems fine.) I suspect that the newest distribution versions rely more heavily on full FPU functionality while the older distributions don't. Which might be why older distributions seem to work a little better. > CRUX - not a "major distro", because it's targeted at "experienced Linux > users". > I am running my selfmade version of "embedded CRUX" on my MPC8540 Boards > based on http://cruxppc.sunsite.dk/wp/index.php which now fully supports > the e500 core features. Thanks, I will start looking into using CRUX. > I bootstrapped the toolchain (binutils, (e)glibc, gcc and friends) from > scratch Did you find any documentation that was helpful when you did this? I'm not really sure how to start this process. Do you basically just download binutils, glibc etc... and compile them using the gcc that comes with CRUX? Thanks again for all your help!
