I have go ahead to look for an alternative cortex ARM cpu for my
company.

I'm  trying to see if I can get an FRDM-K20D50M operational and use that
to program up a MK20DX32VLF5. Is that even possible?
Codewarrior (Eclipse derivative) is free up to 128k but when you try to
download it, you have to wait for someone from freescale to make contact
instead of click and download. I don't know what all that involves so
I'm loosing time here to try things out.

Chris, could you share how you plan on getting a K20 code compiling in
Linux and programming a chip with it? I could use this for the I2C I/O
port expansion chip because its cheaper.
