    Cannot program nor use the CY8C4247LQI-BL493 at 3.3V or 5V only between 1.8 and 2.5V


      My board has a CY8C4247LQI-BL493 and when I try to increase the power supply from the working 2.5V to 5V at about 4V the power increase rapidly triggering the current limit in the bench power supply that is set to 200mA, at 2.5V it use only 30mA


      I tried to set VDDA,VDDD,VDDR to 5V and uncheck Variable VDDA in PSoC Creator without any change


      I used MiniProg3 as programmer and tried also with CYC8KIT-042-BLE


      Programming at 3.3V I get "Detected SiliconID: "FF FF 19 9E" is not in database " message 


      Programming at 2,5V I Get "Automatically Detected Device: CY8C4247LQI-BL493" and it succeeded


      Any suggestion to have the board running at 5V as it was designed to work?
