what's the status of CONFIG_BUILD_KERNEL?
it seems only sama5 has the necessary up_ functions. is this right?
is there a way to run on emulators like qemu?
I have not used the kernel build in some time. It has been used in
products in the past so it is complete and usable but has some
limitations and "opportunities" for design improvements. This Wiki page
provides the full status of the KERNEL build and support for processes
under NuttX:
https://cwiki.apache.org/confluence/display/NUTTX/Memory+Configurations
Only the sama5d4-ek:knsh configuration supports the KERNEL build at present.
