Subject: Re: Make NuttX Tiny Again (pun intended)

Hello,

Is there a tutorial somewhere about how to do this?

There is a little bit of information at this wildly oudated document 
https://cwiki.apache.org/confluence/spaces/NUTTX/pages/139629500/NuttX+Initialization+Sequence
 under "Application Initialization."  There is more information in 
sched/Kconfig under INIT_ENTY, INIT_ENTRYPOINT, and INIT_ENTRYNAME, and

Is the interface between the nuttx and apps repos documented?

I don't think so, but there is this:  
https://cwiki.apache.org/confluence/spaces/NUTTX/pages/139629534/Application+NSH+How-To+s

What apps/Makefile targets are called?

What output binaries are expected by the nuttx final link?

In a FLAT build, the replacement init task will be built into the monolithic 
FLASH image.  In other build modes it should appear at /bin/init

Sebastien
