Have you remembered to run west update after checking out tag v1.2.0? Open a terminal in Desktop/v1.2/nrf and run the following commands:

git checkout v1.2.0
west update

Best regards,

Simon

Hi simon,

               I am facing the same issue while running the west command. I have tried the above mentioned commands but the error is not resolved. Can you tell me the other solution if possible.

Thanks and regards,

Shammi

Oooh. I think I know what's causing the issue, I was maybe too quick to answer earlier. There is a syntax error in the file ncs\zephyr\scripts\west_commands\runners\nrfjprog.py.

In nrfjprog.py-->NrfJprogBinaryRunner()-->get_board_snr()-->elif not sys.stdin.isatty() change it from:

elif not sys.stdin.isatty():
            raise RuntimeError(
                f'refusing to guess which of {len(snrs)} '

to:

elif not sys.stdin.isatty():
            raise RuntimeError(
                'refusing to guess which of {len(snrs)} '

It's strange that I'm not getting that issue I am using Python v3.8, try updating to that.

I would recommend you to use the Toolchain Manager, since everything runs out of the box, and the chances of encountering any errors are minimal.

Best regards,

Simon
