    You can use undocumented mbed_reset() function. To use it, add:

    extern "C" void mbed_reset();

    somewhere before usage.

    I have used this successfully on the MBED LPC1768, but now I've recompiled for the MBED LPC11U24; Reset no longer works, has anyone else noticed this?

    Thanks

    You can use the CMSIS function NVIC_SystemReset() http://knowledgebase.nxp.trimm.net/showthread.php?t=2245

    There is always the alternative of setting the watchdog to a very short period and letting it reset the mcu.
