I am using MM9Z1J638 MCU, but there is a fast chip seems to be debugged by me, under the same environment another development board can enter debugging, but this one can not, how to unlock the chip?(cw 10.7)
The following is the error promotion

Please turn MCU power off (Under 0.1v,

I just ran across this. I am assuming that you have RESETA and RESET tied together. Please note that flashing problems can occur when these pins are connected. A simple solution is to provide a 470nF capacitor at these reset pins to ground. This should allow you to program.
