    Programming PSOC4 with external voltage




      I'm using 5 pins of Miniprog3 with SWD protocol to program my MCU: CY8C4247AZI-M485 .

      I'm having trouble programming my MCU with external voltage supplied (5V) - it doesn't recognize the device.

      When I power the MCU from the Miniprog3 with 3.3V, I can program it without any problem.


      Besides that, the MCU works just fine with 5V.


      Has anyone encountered this problem and has a solution?


      Best regards,
