Yes.

To build 5.15 kernel out of Fenix you need to combine linux & common_drivers.You can check how fenix build the kernel: fenix/config/functions/build at master · khadas/fenix · GitHub

Thank you!
I was able to compile it successfully, now, for the u-boot should I use “Khadas-vims-v2015.01-5.15” right?

Yes, you can use this branch.

Any advice on how to build U-Boot out of Fenix tool?
Thank you

You need to setup the cross compile yourself and check how it work under fenix.

Thank you both for your time and help. I couldn’t get it to work by compiling it myself, so I had to use the Fenix compiler to compile only the U-Boot and now it works. I think I need to customize U-Boot based on the kvim3.h file, is that correct?

I also have another question related to DSI. So I will open a new post and close this one.

Thanks again!
