I tried to look about the boot sequence and seem everithing well with CRP and WDT.
Have someone some idea?

I found the problem that is the following: when i call the go command, the CPU
go in "__dabt" exception. Someone know the possible reason?

Sounds to me like your application might contain some semihosting functions. In which case you'll need to get rid of them for executing without a debugger attached.

So did you debug the reason for the exception? You need to debug it to work out what is causing it.

I try in debug session but just finished the fw upload give the exception. Strange that if i reset by SW(LPCXpresso) the FW run correctly.
