Re: [ECOS] Kinetis TWR-K60N512-KIT questions

Hi jjp

Thank for question, you are coming in right time, A week ago I placed
Kinetis port on Bugzilla.
http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001187
I'll appreciate if you try it and come with feedback.
Note:You need to commit latest version from CVS as it has bugs 1001184,
1001186 integrated.

I am using official eCos 3.0 tools (-m3 of course) in order to maintain
compatibility, but I am keen to try gcc 4.6.

Note: When you send mail to eCos mailing lists make sure it is plain
text, not HTML - because it shall be discarded.

Regards
Ilija

Check if VTOR setting is as desired, 0x20000000 should work. Also stack,
what do you have in mlt files?

Nice to see that Zylin supports Kinetis too.
