I'm getting the following error when flashing the LPC54102 SoC in a lpcXpresso board:

Does anybody know what causes this and how to fix it?

Thanks,

I suspect that the code already in flash has already put the MCU into a low power mode - please try booting the board into ISP mode, then try flashing again:

If that doesn't work, please confirm what version of LPCXpresso IDE you are using and also please provide the actual command being invoked to try to flash the board (I presume that you are using either the GUI flash programmer, or invoking from the command line):

Also, please try fitting a jumper to JP5/DFULink - which should allow the tools to soft load the latest debug probe firmware, rather than using the old version that factory programmed into some LPCXpresso54102 boards. Note you will need to do this before connecting the USB cable from your PC to the board.
