ok Thanks , it is working now but only if my input voltage is 2.5V (the MinProg4 is also suppling power to my board)if I cahnge it to 5V or 3.3V my board stops working do you have any idea how the internal volatage regulator works. I need at least 3.3V because I have othe ICs that works with min 3.3V.
a) Have you powered your board before at 3.3V (externally, with a external power supply)? If yes, what's the consume?
b) if it's possible, pls, share your schematics to check how is connected the power
Either power your board externally or use Miniprog4 to power it. Miniprog4 can supply power to the board, this supply is limited to 200mA and you can select 1.8V, 2.5V, 3.3V or 5V from PSoC Programmer based on your requirement.
