nRF52832 read the image from device problem

[userko]

Using nRFgp tool read the image back from device and save to hex file. I erase the flash with another device and try to programme the hex file, nRFgo shows

            Application c:/temp/Read_1.hex programming failed

            The flash is not erased

Any idea?

That seems to be your problem.

So you need to be looking at why the flash erase is not working ...
