Hmmm.  I'm not exactly sure which 'kind' of reset I should be using.

What I'm trying to accomplish is getting "init 6" or "reboot" to work as
expected.  I.e. JLAPC (Just like a PC  ;-)

I'd like the reset to result a reset to the RPXU2 which restarts my kernel
via 'autoboot'.  Since the 'reset' command in the RPXU and U2 used the
checkstop thing, I figured it would would work OK for me.

I haven't yet studied the reset part of the 823 manual close enough to
figure out all of the available reset modes.

I'll defer to your expertise the selection of the 'right way' to do this.
