tuya TuyaOS Watchdog (tal_watchdog)
Demo: …/examples/os_watchdog/example_os_watchdog.c
TuyaOS examples use tal_watchdog_*, not the TuyaOpen tkl_watchdog_* card.
Pattern
#include "tal_watchdog.h"
#include "tal_log.h"
void example_feed_watchdog(void)
{
OPERATE_RET rt = tal_watchdog_refresh();
if (rt != OPRT_OK) {
TAL_PR_ERR("watchdog refresh failed %d", rt);
}
}
Notes
- Init/start APIs may already run in system bring-up — read the full demo and platform docs before adding a second init.
- Feed from a healthy path only (main loop / dedicated thread), never from a path that can hang while still feeding.
