Hi Michael,
thank you for announcing your upcoming work here.
As a follow up. Is there a way to use cmake in Genode sources? Like a crosscompile file.
There is no ready-to-use solution but your idea should be doable.
As a starting point, you may have a look at the Goa tool [1] that integrates popular build tools like CMake with Genode. The most important parts for the CMake integration are [2,3,4].
[1] https://github.com/nfeske/goa [2] https://github.com/nfeske/goa/tree/master/share/goa/cmake [3] https://github.com/nfeske/goa/blob/master/share/goa/lib/build /cmake.tcl [4] https://github.com/nfeske/goa/blob/master/share/goa/lib/flags.tcl
Note that Goa works on the basis of Genode's depot packages, not the Genode source repository. But I think that the way of how Goa invokes CMake could also work for calling CMake from the Genode build system - similar to how some Genode targets use autoconf via [5].

https://github.com/genodelabs/genode/blob/master/repos/ports/mk/gnu_build.mk Thanks for te quick answer.
I think I will try (already sort of done) to extract which files I need to buld. I hope that I can skip cmake for the emulator.
I also found my backup from my previous aarch64 Genode project which will help me to get the board up and running.
Cooling sorted and I have started coding. Right now it crash in memory
init in Patform::Platform() probably right in when it fetches the addresses I haven't got any trm yet, but from linux boot log I have tried with the first ram added. If I chose a completely illegal address such as 0x0 I get exception from uboot exception handle. Genode::raw works so at least uart and stack is ok. With what I think is a valid address it just stops.. no errro message, and none of my debug prints from Platform::Platform(). I am basing this port on my little rk3399 port.
