nRF Connect "Error while getting readback protection"

Emile

Hi, 

I use nRF connect with a EVK-ANNA-B112 board to program a nrf52832 custom board. Everything was working fine until nRF connect updated to 3.6.1 version. When I try to connect to my custom board, I get this error :

"Error while getting readback protection"

 

There is the complete log:

13:40:45.705	Application data folder: C:\Users\xavie\AppData\Roaming\nrfconnect\pc-nrfconnect-programmer
13:40:45.812	Using nrfjprog library 10.12.1, pc-nrfjprog-js 1.7.6
13:40:59.465	Using nrfjprog to communicate with target
13:40:59.965	Using J-Link Software version 6.88
13:41:00.346	Segger serial: 483066063
13:41:00.346	Segger speed: 2000 kHz
13:41:00.346	Segger version: J-Link OB-SAM3U128 V3 compiled Jul 3 2020 10:46:22
13:41:00.346	Core probed: 483066063
13:41:00.346	Core RAM: 64KiB
13:41:00.346	Core ROM: 512KiB in pages of 4KiB
13:41:00.460	Model: NRF52832_xxAA_REV2.
13:41:10.461	Error while getting readback protection

I re-installed nrf connect 3.6.1 and j-link 6.88 which is the latest version supported version by nRF connect 3.6.1. It didn't resolve the problem. I tried on the computer of my collegue which has the same J-Link and nRF connect versions as on mine.  There was no problem.

What is the issue?

Thank you!

    Hi

    A similar issue a few months ago was reported as well. There the solution was to make sure the programmer power was actually connecting through the board, and that the board was supplied properly. Have you checked whether the cable you're using is working properly (did you use the same cable on your colleagues computer when testing as well?

    Please also make sure that the nrfjprog version is the same on the working and non working computer.

    Best regards,

    Simon
