I'm starting to write a kernel for the H8/500 which is use in some older Mitsubishi ECUs. I assumed that I could use to crosstool to build a gnu toolchain for h8500, but it looks like h8/500 support was dropped a while back and you need to buy GnuPro to get current gnu tools which support it. It seems like I should be able to dig up old enough gnu source a build a version which supports h8500, but I don't really know what issues I'll run into trying to build a cross-compiler with an older version like that. Does anyone have move experience in this area who might be able to help?
