Where to find tutorial for Yocto’s custom device tree creation?
I am using Ka-ro qs8m-mq00 qsbase2 board. Also I am learning Yocto. I am not an Yocto specialist, I’m just learning this topic, so I have some beginner’s troubles.
I faced troubles with SPI and I2C customizing like changes some pins etc. As far as I understand, I need to create my own .dts file that includes existing .dts (in my case imx8mm-qs8m-mq00.dts ?).
Unfortunatelly, I can not find some clear tutorial with this process description. There are some pieces of information about patch files creations, some .bbappend examples etc. But I have not found some step-by-step explanation. It looks like I am near the correct solution, but I can not obtaing image with this customized device tree.
