Hi Mark,
As you are the creator of the 'scarthgap' branch, could you please share
its current status?
Currently, my Yocto layer is based on the Poky 'honister' release,
including meta-xilinx version c165574c (it was stable when I froze our
version).
The past migrations have been time-consuming. This was mainly due to the
lack of clear migration notes (poky is a good counterexample, link
<https://docs.yoctoproject.org/migration-guides/migration-5.0.html#migration-notes-for-5-0-scarthgap>)
for the meta-xilinx layer, necessitating code reading and information
gathering from this email group. Has this situation improved recently?
Due to the required effort, we would like to address directly the latest
LTS of Yocto, aka 'scarthgap'. After switching our layer from 'honister'
to 'scarthgap' and aligning with Poky following Poky's migration notes,
I encountered bitbake errors already at the parsing stage when
processing meta-xilinx recipes, e.g., firmware_git.bb:
bb.data_smart.ExpansionError: Failure expanding variable
fetcher_hashes_dummyfunc[vardepvalue], expression was
${@bb.fetch.get_hashvalue(d)} which triggered exception FetchError:
Fetcher failure: Unable to resolve 'invalid' in upstream git
repository in git ls-remote output for github.com/Xilinx/embeddedsw.git
The variable dependency chain for the failure is:
fetcher_hashes_dummyfunc[vardepvalue]
Is the meta-xilinx 'scarthgap' branch stable? Or should we focus on a
recent version from the master branch? Any recommendations?
We are targeting ZynqMP with U-Boot SPL. We aim to have a clean Yocto
build, avoiding dependencies on external Xilinx tools (e.g.,
meta-xilinx-tools): the only input to the build is the bitstream and the
platform initialization files (_init.c) from the *hdf file.
Thank you in advance for your input.
Regards,
Adrian
