CirnOS currently can only run on the Pi Zero family and the original Raspberry Pi, which only makes up a fraction of the total Raspberry Pi users.

It should be possible to modify the vectors.s, macros.h, loader and build.sh files to create builds of CirnOS that can run on the other models.

To build for the different models, separate scripts should be available such as build-rpi.sh,build-rpi2.sh, and build-zero.sh etc ...

I will work on this issue.

What is the difference between start.elf and start2.elf on rbpi3b+? What about the bootcode.bin?

Don't they both load kernel.img and invoke _start aka ENTRY(_start) in the linker.ld (if present, else its default)?
