Unable to Flash Blinky Sketch

[Tanmoy]

Using Visual Studio Code as IDE with installed nrf SDK v2.9.0 on MacOS Sequoia 15.2

Terminal reads -

west build --build-dir /Users/<UserID>/nrfworkspace/blinky/build_1/blinky /Users/<UserID>/nrfworkspace/blinky

Flashing blinky to Blooper
west flash -d /Users/<UserID>/nrfworkspace/blinky/build_1/blinky --skip-rebuild --dev-id XXXXXXXX --erase

How to get around this ?

I realised that I had a wrong version of nrfutil and needed to upgrade to the latest. I downloaded the file from here - NRF Util

I followed the instruction on the page to also download commands such as 'nrf5sdk-tools' and 'device'.

The version of pyYaml also needed upgrading to get 'west' working again.

I needed another problem fixing in the meantime as I also had a version of nrfjprog which had some permission issue and could only be operated by sudo. I downgraded the utility to 10.24.0.  With this also handled all the boards can now be flashed normally.
