Hi All,
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.
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?
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).

Matthias
Thanks in advance.
