    CY3210-PSoCEval1 - will not program with external power




      Not sure this is the place to post this so please move if necessary.  I am working with the above kit and I have a 12v dc adapter powering the kit.  For some reason, when the external power is applied I cannot program the device.  I keep the power button OFF as I have external power, but the software says "Program Requested" and thats as far as it goes. FAIL.  Jst for the sake of 'why not try' I clicked the power button and I got the same result. FAIL.




      Now if I disconnect the external power and click the power button the device programs.


      How come?




      The other reason for the questions is if the PSOC mini programmer must power teh board this cold be a problem for me should I need to update a device in an end product as the USB programmer will not have enough power to run the board, and program the device.




      And guidance would be appreciated.
