Hello All,

Maybe I'm doing something stupid but shouldn't I be able to run an LPCXpresso board as a standalone board, i.e. cut off the LPC-Link section?

I've tried using the flash icon using a release version of my code but no joy..

Thanks,

Leo

Ah yes, missed the obvious! The LPCXpresso board is a USB project with a USB cable directly wired to it. Removing the LPC-link board removes the 5v -> 3.3v voltage regulator (in there somewhere no doubt)!

Thanks for the help!

I'm not sure what you did in detail  :quest:

Did you separate the boards (target & link) completely?

If so, how do you supply the target?

Which LPCXpresso board are we talking about?

Which program image did you flash? Did it work before separation?

I've set optimizations to none & under

settings>C/C++ build>settings>MUC linker>managed linker script

I've got

library -> Redlib (none)

Still no joy!

Would be stupid to use a semihosting library  :)

Could be an optimization problem. Did you try to build your release version without opimization already?
