Are there any UART bootloader examples for the M52259 that work with projects using MQX?
I am not aware of one.
I have written my own serial boot loader that works with some simple cygwin terminal to manage the serial transfer to the processor, it also has dual bootable images and can run from external memory (MRAM). My bootloader actually boots to a very small MQX image that manages the serial (itty) and flash update (flashx).
