VSRVES01 - DeviceTree

Post by Maciej »

Hello

Here is preliminary device tree source file, it can be compiled with dtb
dtc -I dts -O dtb -o catbd.dtb catboard.dts

dtc as command comes from device-tree-compiler package (at least on debian based systems and derivates like ubuntu, devuan), but also it is a part of linux kernel sources and can be invoked from kernel tree via scripts/dtc/dtc.

Also, preliminary configuration for kernel 6.1, which still needs one line patch unfortunately.

There are a lot of things to add and tweaking Linux, boot loader and what not are one of those things.

The document is pretty much work in progress. But I don't promise any specific chapter to be updated.

We are very much working on those TBDs because our full intention is to make it possible for anyone to compile their own Linux to the VSRVES01. But, we have limited resources, and as Hannu said, we cannot guarantee any exact data at the moment. However, rest assured that we will release the information immediately when it's ready and tested.

Kind regards,
