Windows10 Installation: Failed to run west update

[r0n9Y]

Failed to run west update when I try to install Zephyr SDK first time
with the error fatal: a54986aa98db4082ac56b582843bb5b5435208a6^commit: not a valid SHA1
Here is details of the error:

ERROR: update failed for multiple projects; see above

• Zephyr version: 3.1.99
• Following the installation guide for window from https://docs.zephyrproject.org/latest/develop/getting_started/index.html
• Unable to get the Zephyr source code
• env: Windows 10 version: 21H2 19044.1826
• git version 2.36.1

Question
Is it possible I can find pre-built binary somewhere? It is unusual that the ppl have to build the SDK from scratch. And I am trying to avoid to use PlatformIO with Zephyr.

@r0n9Y which west version are you using? west --version

You do not need to build the SDK from scratch, this is Zephyr and its source code and not the SDK.

[r0n9Y]

West version: v0.13.1

@r0n9Y can you say which shell you are running on? We only support cmd.exe on windows, so if you're using the git bash shell, please retry on cmd.exe.

Per our discord chat, here are the logs:

[mbolivar-nordic]

Thank you @TomzBench, and you as well @r0n9Y, those are useful logs. I was able to take a look at them and I got an idea; could either of you please try this PR and see if your issue goes away?

zephyrproject-rtos/west#599

You can install with:

pip3 install git+https://github.com/mbolivar-nordic/west@project-git-on-windows-hotfix 

Then test again.

To go back to another version after you're done testing, e.g. v0.14.0, you can do this:

pip3 install west==0.14.0

[TomzBench]

Still fails with same error. West still advertizes 0.14.0 so I hope i installed the hotfix correctly.

Here are logs again, including installation of venv and west so you can verify i test correctly.

I got the same issue, and solved it myself.
I'm running Windows 10 with Python 3.10.5, installed latest west which is 0.14

I did look into source, found this function
https://github.com/zephyrproject-rtos/west/blob/main/src/west/manifest.py#L861

    def sha(self, rev: str, cwd: Optional[PathType] = None) -> str:
        '''Get the SHA for a project revision.
        :param rev: git revision (HEAD, v2.0.0, etc.) as a string
        :param cwd: directory to run command in (default:
            self.abspath)
        '''
        # Though we capture stderr, it will be available as the stderr
        # attribute in the CalledProcessError raised by git() in
        # Python 3.5 and above if this call fails.
        cp = self.git(f'rev-parse {rev}^{{commit}}', capture_stdout=True,
                      cwd=cwd, capture_stderr=True)
        # Assumption: SHAs are hex values and thus safe to decode in ASCII.
        # It'll be fun when we find out that was wrong and how...
        return cp.stdout.decode('ascii').strip()

If I get the idea right, it should give a result like xxxxx^{commit} that tells git the refer type is commit and hash is xxxxx?
My simple testing code gives me correct result, that means this is not a Python issue

>>> rev:str = "53d3415c14d60f8f4bfca54bfbc5d5a667d7e724"
>>> print(f'rev-parse {rev}^{{commit}}')
rev-parse 53d3415c14d60f8f4bfca54bfbc5d5a667d7e724^{commit}

Then I checked with Procmon tool from SysinternalsSuite, the command that west invoake git is correct
I was using powershell with git that from Msys2 bin folder, seems git from Msys2 do not like it, and dropped {} around commit somehow
The solution is simple, either install a windows version git, or get a portable git and make a script put the folder containing it as the FIRST path in PATH

[TomzBench]

I confirm your solution fix for me as well.

I had windows git installed, but a cygwin git was favored on my path. so by changing my path variables order to favor the windows git, the solution worked as you said.
