Cannot apply the reset pin functionality | Cannot enable RESET button

[Navneet]

Hello,

Device: nrf52840DK

Software: nRFgoStudio (version 1.21.2.10)

Operating System: Windows 10 (updated)

I am not able to enable the reset pin. I am trying to do so via nRFgo Studio. I am getting an error. Please look at the following image for reference.

I also tried the command line option (using nrfjprog). It succeeded but, the Reset button still doesn't work. Please look at the following image for reference.

Thank you.

nRF Go Studio is deprecated, it does not support nRF52840, and I think you'll need to download the latest version of nRF5x Command Line Tools. 

What version of nrfjprog and J-link driver are you using?

[Navneet]

I am using the following versions:

nrfjprog version: 8.5.0
JLinkARM.dll version: 6.34g

[haakonsh]

My nrfjprog is at 9.7.1. I think you need to update.

Okay, and the command I used was correct?

nrfjprog --family nrf52 -p should work?

or

nrfjprog --family nrf52 -r would work?

and what should be the value for argument --family?

nrf52 was the only thing that worked, nrf52dk threw an error.

[haakonsh]

I believe nrf52 is the correct argument with --family. Both --pinreset and --reset should work.

Hey haakonsh I was to reset the device. But neither of them work when reset.

My main criteria behind using reset was to enable the pyTerm serial port Input/output. I am not able to see the output always and neither am I able to use shell commands. It works sometimes but inconsistent, so, I was hoping reset would fix the problem. (suggested by,  https://github.com/RIOT-OS/RIOT/issues/9971).

Also, I noticed something weird. If I have 2 devices connected. If I flash twice (at the same time or one after the other) with different PORT numbers ('/dev/ttyACM0', 'dev/ttyACM1'), both times, the same device gets flashed. (the only workaround is to plug and flash one device at a time). In my opinion, The code I am using is irrelevant, because the same thing happened with multiple codes.

Operating System: I am using RIOT OS to flash.

Thank you.

-We need more details.

-I'll ask around if anyone have experienced a similar issue. Are you able to consistently reproduce this issue?

"Operating System: I am using RIOT OS to flash."
- Are you talking about DFU over USB or Serial, or flashing via SWO?

Are you using a Virtual Machine?

1) I was able to perform pin reset successfully. Reset should start the execution from the beginning after I push the reset button, that is not happening. 

2) what kind of detail is needed here? Screenshot? I am not able to see any output like print statements or any of logging.

3) I am not familiar with either of the two terms. But, the device is connected via USB and I use the following command to flash

"BOARD=nrf52dk make flash term".

In the process, JLink connects with the device.
