We have an issue during programming steps.
During flash firmware and we are having the error that appear on screen.
This happened after we test 4 boards, and on the number 5th we have this message.
WE go back to try to program one of the previous board and we have the same symptom.
PC is recognizing the miniprog, but when we are trying to read, erase or program the software return back this error and no detect the device (CYPD3125 automatically).
Please double-check the programming parameters under the Programmer Panel in case something changed to see if you have the right settings. MiniProg3 has five indicator LEDs, can you tell me what you see?
Please refer Troubleshooting PSoC® 3/4/5LP Programming/Debugging Issues - KBA210619 to see if it helps.
