Lpc2000

Yeah, I call iap_entry(command,result) and the next line of the code is printf something and it never calls the printf. I pretty much copied the philips code from the app note because this stuff is new to me!(Like most of it!!!) so it must be incorrect parameter passing??

When you say "nothing happens at all", what do you mean? Is it stuck 
in the IAP code or did it cause an exception?

There are a few things that I can think of that might be causing 
problems:
* Incorrect set up of parameters. Likely to cause a data abort.
* Incorrect set up of the thumb bx stuff. Likely to cause a prefetch 
or other abort.
