If the Windows long path doesn’t prove to be the issue, you might check your west.yml and make sure that the repo is listed in that manifest. The “ERROR: update failed for project trusted-firmware-m” bit looks a lot like what you would see if the repo info isn’t present in the west.yml file or has an incorrect URL/SHA, etc.

- name: trusted-firmware-m

      revision: 7c88781953ce7146878bd8bd724e175fdbc298c5

      path: modules/tee/tf-m/trusted-firmware-m

Another potential issue could be some kind of git/github creds issue. Occasionally refreshing git creds will fix this kind of thing, too.

Hi Srikanth,

I don’t know if this is causing your problem.  But I see your Windows path is somewhat long at C:/Users/vimel/SRIKANTH/my_workspace/projects/Projects_2021/ZEPHYR/SOFTWARE/zephyrproject.  I know Windows sometimes has issues with long paths.  Have you tried installing Zephyr in a different directory that has a shorter path?
