Because the EVK board (lpcxpresso54608) we were able to obtain (revision B) does not provide a connection to UART0 for reflashing, I'm trying to implement reflash via SPI (FlexComm3). I do not see any configuration info. I assumed that my master processor would be the SPI master, but that may not be the case. Are there any examples or additional information as how to do this. So far all I have to go by is the LPC5460X user guide - UM10912.
