I keep on getting this error.
I am using a custom board layout with a CY8C3244LTI-123 chip. There was an error while execute any function (programm,checksum, read, verify, or erase.) : (PSoC Programmer received error (FAILED! Can not enter Debug Mode of PSoC3 device)).
PSoC programmer version is 18.104.22.1688
I made next the custom board layout with another CY8C3244LTI-123 chip and tried enter Debug Mode, but unsuccessfully.
When I tried programming the device out of PSoC Creator, then device CY8C3244LTI-123 is visible, but no by connecting.
When I received these chips, the package contains the inscription "p/n:CY8C3244LTI-123-ND". What it means "ND".
I think I got the problem. I see that in your case you are not connecting the VTARG pin anywhere. You need to connect the VTARG pin of Miniprog3 to VDDIO1 of PSoC. Miniprog3 measures the voltage on VDDIO to see if the device is powered, since the SWD port pins lye in VDDIO1 quadrant of pins.
