JianyuWang0623 opened a new pull request, #20098:
URL: https://github.com/apache/nuttx/pull/20098
## Summary
Documents the per-service `console [<device>]` option added to nxinit
by the companion apache/nuttx-apps#3776.
`Documentation/applications/system/nxinit/index.rst` is nxinit's only
existing doc page. This adds `console` to the option list in "Services
and Options" and a dedicated subsection explaining:
- what the option does (open the given device, or
`CONFIG_SYSTEM_NXINIT_CONSOLE_DEV` if omitted, and dup it onto the
service's stdin/stdout/stderr before spawning);
- why a plain shell service needs it while `nsh` does not (`nsh`
already does the equivalent internally via `nsh_consolemain()`);
- why a USB gadget console (CDC-ACM/PL2303) additionally needs the
gadget itself brought up first (e.g. via `exec -- sercon`), since
the device does not exist until then, unlike a plain UART.
## Impact
Documentation only, no code change.
## Testing
```
$ tools/checkpatch.sh -g HEAD
✔️ All checks pass.
```
