The tar should be in the "${WORKDIR}/git" directory but it will not
work as you don't tell bitbake to unpack it.<br>
<br>
You repository with tag "v0.1" contains only a README.md!<br>
<br>
The common use case is to put all sources into the git repository.
Why you want to save a tar in a git repository?<br>

Have you check the content of the

Are you sure you have change the S variable? The error still
reference the common directory ("${WORKDIR}/${PN}-${PV}").

It looks as something went wrong. Please clear the old package and
try again or increment the PR number.<br>

No, this are subsequent errors of the missing toolchain.cmake.<br>
