When I was originally developing the kernel mode, I wrote this:
https://cwiki.apache.org/confluence/display/NUTTX/Memory+Configurations
That was mostly my notes of what I had worked on and my roadmap that was
guiding me through the kernel mode development. I burned out on that
before finishing everything and since then several other people have
worked with this build mode. I don't know the current state.
I would be great to have a similar, updated document. Although this old
Wiki page is out of date, it still might answer some questions about
what's there and why. There is even a section on "Partially Linked vs.
Fully Linked Objects" in the section of things not finished.

Are there any examples of a gdb setup to debug a userspace process? One key
issue is to setup the section offsets to match the final application

I was actually quite surprised that Nuttx applications are still partially
linked with a protected build and that all sections overlap (start at 0) in
the elf file. I had expected the application would be fully linked to
virtual addresses as per linux and another RTOS I used previously. Is this
something that can be changed relatively easily, or are there some
significant challenges?
Kind regards,
Andrew
