Hi Mathias,
Thank you for the reply.
My company is building a product that uses QSMP-1570 module from KaRo
Electronics (https://www.karo-electronics.com/qsmp) and the modules
itself is based on STM32MP1 processor from ST. They have application
software that works on standard openSUSE 15.3 distro and Intel based
board. They now want to build similar product based on the QSMP-1570
module and prefer to use openSUSE again so that the application does
not need to get ported to a new Linux distro. The module itself comes
with full Linux support using Yocto. My task now is to research the
feasibility of spending the time to port openSUSE to the QSMP-1570
module.
I have experience with Yocto/openEmbedded and embedded Linux, but
have never used and build openSUSE before. Where should I start
looking? What's your opinion - how hard would it be to make openSUSE
work on this board?
I'd advise you to start looking into any not-yet upstream patches in
the kernel or U-Boot that would be needed. I hope there won't be any
but who knows. I suppose using the Yocto recipes that will be easy to
find out.
OK, clear on that. Will do.
After that you will need to have to find out how the boot works. Will
U-Boot be part of the SD card image or will it be flashed in some
SPI-Flash or something similar. Do you need to get any specific binary
FW on the SD card to boot? Do you need to 'dd' U-boot a on specific
offset on the SD card?
OK, clear on that too. I'm waiting for an EVK of the module, then will
get access to the additional docs and will be able to flash and test the
whole thing.
Once you have an overview of that, we can start to have a look if we
are missing any kernel config options. And in parallel set up a kiwi
image to create a openSUSE Tumbleweed JeOS image (as a start).
Any advice on where would be the best place to start learning the
openSUSE build basics and setting that up?
Thanks.
Best regards,
Panayot
