problem programming CY8C20447
I am tyring to use ISSP programming to program CY8C20447 using MiniProg1. MiniProg is not recognizing the device.
I get the message:
FAILED! Can not Acquire Device! Please verify the device connection to the Programmer
Please, check the following items:
- the connection between the programmer and the PSoC;
- the correct programming protocol is selected;
- the correct connector option is selected.
Attatched you'll see the design (the same from the design guide) I'm testing.
I tried to power the circuit from Miniprog and externally (power cycle and reset).
One strange thing I've noticed is that XRES signal has 3,1 V. I would expect 5V. May be my miniprog is damaged? It's brand new (first experience with Cypress)
