    I did solve the last issue.  

    Thumb-2 instructions are only supported in unified syntax mode
    so adding .syntax unified fixed the problem

    Yes, I took the path of least resistance.  I used some modules from a company in the US called dzx designs (www.dzxdesigns.com).  Apart from the fact their stuff worked out of the box, they also had a messaging model builder, which auto-generated the enumerations and exchanges for both the LPC1788 firmware and the host-side PC.  In all, I would say they saved me a good 4-6 weeks of work!  So if you are doing a home project, this is all free, if it is a commercial development, it is a one-time license of $500 per product.  Money well spent believe me...

    Thanks a lot. I will download and try, will be happy to pay if it will save me time. Did you have any issues running the samples on crossworks? I saw they are for keil and iar only.

    I think it required I build from scratch, could not use their demo projects.  As it is all in C, it was fairly painless.  There are some config setups, like editing the xml memory map to indicate the entry point for the code.  I would be happy to send a build to you, but you should probably work with DZX.  The guy who is the programmer there (Tyler) was extremely helpful.  You should mention we spoke, I have had a lot of dialog with Tyler as I did uncover some early bugs.  Right now, everything is rock solid.  Good Luck!
