west flash with nrf5340 not working

[StefanHri]

Hi

I have a new NRF5340-PDK board.

I am using Zephyr OS to build my application like that:

west build -b=nrf5340dk_nrf5340_cpuapp

However, flashing with:

west flash 

doesn't work. I am using the latest version of nrfjprog v10.12.1. on Ubuntu 20.04.

Hello, Stefan!

Thanks for reaching out. To help you with the issue could you answer the following questions:
- What version of the nRF Connect SDK are you using? 
- What version of West are you using?
- What version is your nRF5340 PDK?

Best regards,
Carl Richard

[StefanHri]

Hi Carl,

- What version of the nRF Connect SDK are you using? 

    -I am not using the SDK but the standard Zephyr OS version 2.3.99

- What version of West are you using?

   - West version: v0.7.2

- What version is your nRF5340 PDK?

   - PCA10095 0.8.0 2020.24 960163169

I also tried to connect to the board using NRF Connect v3.6.1 Programmer tool (version of the programmer tool 1.4.8), which also does not work. I am getting the error message: Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.

[Carl Richard]

Hello again!

I understand. Your logs report the following: 

2021-Jan-29 00:46:17  nrfjprog version 10.9.0

It seems like an old version of nrfjprog is used. Can you ensure that version 10.12.1 is actually installed and used? 

In addition, downloading the latest J-Link Software and Documentation pack has fixed similar issues for Linux users earlier. I would also recommend that you update west to the newest version.

Best regards,
Carl Richard

[StefanHri]

Thank you for the hint. Now I updated and made sure that both are the newest version, however no improvement. my current nrfjprog and JLinkARM.dll are:

nrfjprog version: 10.12.1
JLinkARM.dll version: 6.94b

and the log file:

Great. Too bad it didn't help. 

Could you try to run "nrfjprog --recover"? And what is the output of the nRF Connect Programmer app now?

Best regards,
Carl Richard

Unfortunately no improvement. "nrfjprog --recover" produces an error with the error log:

Understood. I will do some digging! Just for clarification: you have not done any modifications to the HW, with regards to switches, solder bridges or similar?

Ok! Could you try to reboot your computer? It was successful for the Linux user in this thread.

I'll have access to a Ubuntu desktop tomorrow and can do some more testing then.

Best regards,
