It's very likely that I'm doing something wrong so I'm reaching out for
help.  All I want to do right now is to get Blinky working on an nRF52.

I followed the tutorial and built the boot loader and blinky.  I then
created an image so the boot loader would be happy about the magic
number.

I used GDB and the Black Magic Probe to flash the boot loader ELF file
to address offset 0x0000.  Then I used the `restore' command to flash the
blinky IMG file to offset 0x8000.  (I debugged the jlink shell scripts
to figure this out.)

At this point I would expect that resetting the board would cause the
LED to blink once a second.  Of course, that's not happening.

So I started GDB, used the `file' command to load symbols from the boot
loader ELF file, and restarted the boot loader with `run'.  That's when
I get:


  Program received signal SIGSEGV, Segmentation fault.
  os_pkg_init () at repos/apache-mynewt-core/kernel/os/src/os.c:223
  

I stepped through the code and I end up inside `os_start' which appears
to only have `assert(0)' as its body (because `#if
MYNEWT_VAL(OS_SCHEDULING)').

Like I said before, I'm probably doing something wrong and now find
myself out in the weeds chasing a ghost.  I would love some insight from
anyone who wants to share.

Thank you.
