are talking about and have had the exact same issues. We have managed to
fix or workaround all of them. In most cases by reducing what the SoC layers
do by BBMASK'ing all non-essential BSP recipes, reverse engineering the
machine configuration and bbclasses to only use bare minimal ones.
I can only hope that our feedback in terms of patches and workarounds also
going back the supplier chain(s) and you at some point see the same patches.
For example we updated the yocto open source layers from 2.5 sumo to 3.0 zeus
with very minimal support from the SoC and other suppliers and their layers
are still only compatible with 2.5 sumo, officially. Also switched from
using a custom Android based binary toolchain(s there were multiple
at some point) to using meta-clang.
If you have detailed question or problems, it would be nice to discuss them
here, but I know that some details may be closed. At least some general
aspects how to debug issues may be discussed without exposing too much
details or, well, company names.
