hello

i have had the same problem. When i want to call the iap_entry
function the processor hang up. 

I have said the gcc that it is thumb code but it still don't work.

The solution was that i update the onchip philips bootloader to the
actual version 1.63. And now it still works perfect.

i hope i can help you with this solution.

best regards Tobi
