    The Keil tools will automagically create a checksum for the interrupt vector table. As long as you download that address range, the NXP boot loader should be able to sum all vectors and get a total of zero. This indicates that there is an application loaded, and the NXP boot loader will then start your firmware.

    If your download doesn't contain the interrupt vector table - or downloads it to the wrong address - the NXP boot loader will (as intended) wait in an infinite loop for anyone to connect on the monitor port and feed it a new firmware.
