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

Hi,
I modify the code according to http://sourceware.org/bugzilla/attachment.cgi?id=5340&action=diff
which is same bug you are talking about.

I will begin to test your HAL as soon as possible (maybe tomorrow).

Regards.
Note :? I'm using cortex-m3 support on Zylin zy1000.
