OM11043 (LPC1768 Dev Board) Debug Connector?

johnwhitmore — Mon, 21 Aug 2017 11:01:54 GMT

I'm looking at the NXP OM11043 LPC1768 Dev Board [1] but can't see a JTAG, or SWD Connector. I want to try things out both programming an LPC device and also using the various debugging tools.

Is this a case of going through the Datasheet for the LPC1768 and working out which pins on the 40 pin 0.1" header are required for a debug header and connecting them to a connector suitable for a J-Link style device. I'm sure I must be missing something as surely a Dev board would have a JTAG Interface?

Hi John,

This ARM MBED board does not have a SWD or JTAG connector, it has a built-in USB programming interface that is as simple as using a USB Flash Drive. You can find the schematics and additional information about the board on this link:

https://developer.mbed.org/platforms/mbed-LPC1768/

If you want a development board with a SWD connector for external debug probes then I would recommend you to use our LPCXpresso board for LPC1769 with CMSIS DAP probe:

Hope it helps!
