We bought two LPCXpresso boards (with the LPC179 processor) and used them to develop our application, using also CodeRed IDE.

Now we have designed our own PCB board and wanted to test the code on there. We broke the connection on the LPCXpresso board between the JTAG and the processor, then connected the JTAG pins to our board.

The problem is that when we tried to download and debug the code, we got an error saying that the ID of the processor was different than expected.

Is the JTAG tool of the LPCXpresso board fixed to use only the processor that comes with this board ?
