Next, add a delay of 1500ms. The documentation states that system resets are only caused by the RTC watchdog timeout or power cycling the device. Once it is running the timeout cannot be changed and the WDT cannot be stopped either. 25s, 0. As the watchdog reset can not occur during the watchdog period that we set, hence the watchdog triggers the interrupt that causes the onboard LED to toggle. Backtrace from the hang leads right back to: lv_refr_vdb_flush(). The Interrupt Watchdog Timer and the TWDT can both be enabled using Project Configuration Menu, however the TWDT can also be enabled during runtime. 3 me-no-dev/AsyncTCP @ ^1. Each page uses an AsyncWebServerRequest to serve (send) each page from SPIFFS. The chip has three watchdog timers: one in each of the two timer modules (called the Main Watchdog Timer, or MWDT) and one in the RTC module (called the RTC Watchdog Timer, or RWDT).

Den kompletten Quellcode sehen Sie in Code 7. In one of those scenarios, the watchdog timeout occurred just as we were entering the ISR! This problem appears to be a result of something on Core 0 failing to service the watchdog frequently enough. A CPU reset resets either one or both CPU cores but a system reset is similar to a power-on reset where the entire ESP32 is reset (CPUs and peripherals). Jan 19, 2023 · ESP32 only has one watchdog timer, so it does not require specifying the “id. May 31, 2024 · ESP32 Core 3. e. Jun 2, 2024 · Well it looks like the ESPAsyncWebServer is not very asynchronous. Failure to do so will result in a TWDT timeout. 0. Watchdog Timers.
