553b71c made production the default but broke configure+link:
- ZEPHCORE_COMPANION_USB sat inside the role choice (recursive dep)
- CONFIG_RESET_ON_FATAL_ERROR was an undefined, unimplemented symbol
- USB companion sources still gated on CONFIG_LOG, not ZEPHCORE_USB_STACK
Move the USB toggle out of the choice, add a real
ZEPHCORE_RESET_ON_FATAL_ERROR Kconfig + k_sys_fatal_error_handler that
cold-reboots, and match the CMake USB guard to ZEPHCORE_USB_STACK.

* Production reboot-on-fatal-error handler.
|
|
*
|
|
* Zephyr has no built-in Kconfig to auto-reboot on a fatal error — the
|
|
* default k_sys_fatal_error_handler() (weak, in kernel/fatal.c) flushes the
|
|
* log and calls arch_system_halt(), spinning forever. For unattended mesh
|
|
* nodes that is the wrong behaviour: a transient stack overflow / CPU
|
|
* exception / k_panic should recover the device rather than wedge it until a
|
|
* manual power-cycle.
|
|
*
|
|
* When CONFIG_ZEPHCORE_RESET_ON_FATAL_ERROR=y (production default; debug.conf
|
|
* forces it n so a debugger can inspect the halted core) we override the weak
|
|
* handler to cold-reboot after flushing the panic log. When it is n this
|
|
* translation unit is empty and the weak default applies.
