Hi,

I've been evaluating LPCXpresso v6.1.2 as an offline tool chain to work with my mbed LPC1768 MCU however I have encountered a problem when trying to run a debug session using the CMSIS-DAP interface. After the image is downloaded to the device it restarts which upsets the CMSIS-DAP connection. If I manually copy the image to the device and then start a debug it works.

Is there any way to restart the CMSIS-DAP session to cope with the device reset after an image download?

Sorry, we have not used that board - and I don't have one (it is not possible for us to have every 3rd party development board).

Have you tried debugging using the following mbed board

http://mbed.org/platforms/Seeeduino-Arch-Pro/

The CMSIS-DAP firmware used by this board is one I'm using.

LPC1768 and LPC4088. Both work.

Ok thanks I'll give it ago, out of interest which mbed enabled board did you test the debug on?

There are no special settings. To make sure that you have not broken anything, you can delete you existing launch configs and the press the Debug button in the Quickstart panel. It will reconfigure everything for you

To rule out my debugger settings can you please let me know the correct settings for CMSIS debugging.

Yep Standalone board, got latest CMSIS-DAP firmwire, I ran a similar test using uvision 4 and all worked fine.

Are you using a standard LPC1768 mbed board that is standalone (i.e. not plugged into any other board).

Are you also certain that you have the very latest CMSIS-DAP firmware programmed in to the mbed board?

Platform Windows 7 64 bit

Get the same result creating a LPC17 project and erasing all flash.

Don't now if this helps but this is the image I used to program the mbed interface side of things.

Debugging a "hello world" program created using the LPC17 project wizard seems to work fine here on an mbed board connected via CMSIS-DAP.

I wonder if this is somehow image related. Can you try creating a test project using the project wizard and seeing if that debugs correctly?

If you still see problems, it might also be worth trying a mass erase of the flash before you program:

Also can you confirm which platform you are using. I presume Windows from the debug log - but XP, 7, 8 and 32 or 64 bit?
