Thank you for that piece of info, Scott!

May I expand the question one bit, and ask whether the user-mode binaries compiled for the e300 will generally work for the e500 -- or, vice versa? Is one choice safer than the other?

I know for sure that we take a big hit on floating-point ops, but are there other things I am not considering?

No, it is not possible.  They use different MMUs, and the kernel does not support choosing between them at runtime.


I was surprised to see that the e500v2-targeted toolchain did build
the kernel for the e300 board just fine. Don't know whether this will
always be true?

"always" is a strong word, but it should generally work.
