rv,
The dbug download for 5235 includes make files for Greenhills, Diab, and Codewarrior.
The debug will build in GCC.. You may just have to craft a Makefile for it.
I believe we have some makefiles for GCC around somewhere.
The free version of Codewarrior should also be able to build debug as well.
Let us know if you need more help.
We now support a boot loader called Uboot that is designed to be built with GCC. It is very popular with other CPU archs and all the Linux guys out there. Checkout the Denx website on Monday the 17th. I think the next release of Uboot is scheduled for this coming monday and it will have several new ports for ColdFire products.
If you need further help, please don't hessitate to send in a customer support request on our website.
As for best compilers.
GCC has gotten a lot better. Check out CodeSourcery's website. I think for a small price you can also get a fully supported IDE (Eclipse based) from them. The compiler is a free download, but the IDE (with GDB stub to P&E wiggler) is available for the small charge.
Diab is trusty and true. It has supported ColdFire for many years.
GHS is still the industry leader in reliable compilers and generating great code.
CodeWarrior is a good IDE with everything you need in one place.
