Thanks Marte,

I have used Nordic MCP and AI assisted development.
Trying to see if I can compile it.

Thank you for your help.

Best regards
Jens

Hi,

Depending on your project, it might be easier to start from scratch in v3.4.0.

If you instead want to migrate, we have migration guides in our documentation under Migration notes. Make sure to go through the migration guide for every version.

This can also be done even more easily using the Nordic MCP and AI-assisted development. This video shows how to migrate from one nRF Connect SDK version to another: https://www.youtube.com/watch?v=zziyMzixQZg. You can see how to get started with the Nordic MCP here: Nordic MCP - Get Started.

Best regards,
Marte

Do you have a step by step migration description? I want to migrate to SDK 3.4.0

Hi,

I recommend upgrading to a newer SDK version if possible.

I got a colleague to test on macOS, and they were also unable to reproduce the issue.

Can you try deleting the entire Matter environment folder and rerunning bootstrap?

Inside the modules/lib/matter folder, run:

rm -rf .environment/

source scripts/bootstrap.sh

If this does not work, you can also try deleting the keychain entries in addition to the environment before rerunning bootstrap:

security delete-generic-password -s cipd -a cipd 2>/dev/null || true
rm -rf ~/.cipd-cache ~/.cipd-cache-dir ~/Library/Caches/cipd
rm -rf .environment/
source scripts/bootstrap.sh

Best regards,
Marte

I am running macOS.

I can reach directly:

HTTP/2 405

content-type: text/plain; charset=utf-8

allow: GET, OPTIONS

x-content-type-options: nosniff

x-cloud-trace-context: e39af654636f95d54248ce4268b9533b

content-length: 19

server: Google Frontend

cipd logout does not work.

Tried many tricks including erasing cache - nothing works.

I could change SDK - works smooth with e.g. SDK 3.0.0 , but it is cumbersome - would love to stay on current SDK.

Hi,

Are you on Linux or macOS?

I was not able to reproduce the issue on my side (Ubuntu 24.04), so it does not seem to be an issue with the OAuth client ID in v2.7.0.

It could be the network. Are you behind a corporate proxy, firewall, or VPN? If so, can you try without VPN or with a different network?
Since the issue is reaching https://ci.chromium.org, can you see if you can reach it directly from your network? For example, with

curl -I https://ci.chromium.org

It might also help clearing CIPD credentials and cache:

cipd logout
rm -rf ~/.cipd-cache
rm -rf ~/.cipd-cache-dir

Have you tried newer versions of the SDK?

Best regards,
Marte
