Should you at least use one method to give OS the basic heap? Can you boot
nuttx into nsh with the current configuration?

Subject: New unused variables warning in nx_start()
In function nx_start() (sched/init/nx_start.c), if none of
MM_KERNEL_USRHEAP_INIT, CONFIG_MM_KERNEL_HEAP, or CONFIG_MM_PGALLOC are
defined, the compiler warns about unused variables heap_start and
heap_size:
init/nx_start.c: In function 'nx_start':
init/nx_start.c:552:14: warning: unused variable 'heap_size' [-Wunused-variable]
size_t heap_size;
^~~~~~~~~
init/nx_start.c:551:17: warning: unused variable 'heap_start'
[-Wunused-variable]
FAR void *heap_start;
^~~~~~~~~~
I wonder if there is something wrong with my configuration (should one of these
always be defined?) or if it's valid to have none of them defined and I should
make a change that eliminates the warning?
Thanks,
Nathan
