void tesaiot_run_protected_update_isolated_test

(

void

)

Interactive end-to-end Protected Update against the isolated test slot; blocks on scanf().

Run the Protected Update path end to end against the isolated test slot, leaving the live certificate untouched.

Contract

Runs the Protected Update path end to end against the isolated test slot, leaving the live certificate untouched. No template call site exists; the sole real caller is the archived MicroPython optiga.clm_menu() binding (modoptiga.c:1681), which refuses while "optiga not initialized" — the example below is modelled on that guard. Preconditions: optiga_manager_init() and the application opened (in MicroPython, optiga.init() does both and also pauses CM55 touch polling); the ported test creates its own optiga_util_t but never opens the application. Interactive: it blocks on scanf() (tesaiot_protected_update_isolated.c:103) and depends on retarget-io polled stdin on the CM33_NS UART; it returns only when the menu's exit option is chosen — never call it from a task another subsystem waits on. Requires a build with ENABLE_OPTIGA_CLM=1.
