Dear users,

we are currently developing a geotracker that builds in an NXP lpc11u35/401 microcontroller. We are experiencing the following problem:
the debug version of our firmware runs perfectly through our emulator, buti if we run the same firmware in release mode the device gets stuck and the uart handler that manages the communications between microcontroller and gprs module does not communicate properly (wrong messages from gprs module).
We run both debug and release firmware with no optimization.
What can be the reason to this problem?

Thanks a lot for your support.
