Upgrade version of Zephyr with current version of NRF SDK

[4DoorToyota]

Hi, 

There are currently is a driver prsent in version 3.4 of the Zephyr SDK that isn't part of the version 3.3.99 that is currently used with the NRF SDK version 2.4.2. 

What I would like to do is take my installation of the NRF SDK and upgrade the version of zephyr from 3.3.99 to 3.4. Is this something that is possible or am I likely to experince a large number of bugs and issues? 

Does anyone have any experince with doing something like this?

Hello,

Thank you for posting this question to the DevZone community!

Zephyr v3.4. is used by NCS main now, as well as by the two most recent development tags. I see two possibilities for you to switch to the 3.4 version of Zephyr.

1. You can switch branches for Zephyr in your NCS installation. Open a command line from your NCS v2.4.2 installation directory and execute the following:

cd zephyr
git fetch --all
git checkout ncs/main
west update

2. Switch to the main branch, the v2.4.99-dev1, or the v2.4.99-dev2 tag of NCS according to these instructions.

Best regards,

Maria
