Hello.

If target PSoC has XRES accessible, I suggest changing Programming Mode from Power Cycle to Reset mode (unless Power Cycle is how the pcb has been designed).

Also, according to screen capture, you've not connected Miniprog Vtarg signal to target.  This is evidence shown by Voltage reading of 0mV.  Or, you have not clicked on the Toggle Power icon to switch power on, the blue colored circle directly below the word Options in PSoC Programmer menu bar.

If using XRES, I suggest a 4700-10000 Ohm pull-up resistor.

Hi @RAM_MARSAKATLA 

I believe you are using a custom board with the PSoC 4 device. This issue can happen when the core is powered at a higher voltage than recommended. For example, the maximum recommended voltage for PSoC 4 Vccd pins is 1.89 V. This will cause the above error and can damage the core as well. Can you please cross-check the Vccd connections?

Thanks and Regards,
Leo

I have verified the core voltage it's around 1.8V. The device is operating at 3.3V. During the programming this is stable.

I am using miniprog4 programmer. 

In the board this controller circuit alone powered. and other circuits are not powered.  

please share any other details I need to check.
