When I debug in MDK.
It will "Could not stop Cortex-M3 device， please check the cable"
So I can't continue debug. Why appear this problem?

Thanks!

Is the LPC1768 part of a commercial development board or your own design?

What is the current JTAG clock configuration, speed and setting?

Have you disabled any watchdog timers which maybe resetting the device during debugging?

Maybe the watchdog! Before I learning the watchdog timer.There is no this fault!
I am going to have a try!
