esp32s3遇到Task watchdog got triggered. The following tasks did not reset the watchdog in time故障怎么解决？

问答对人有帮助，内容完整，我也想知道答案 0 代码重现主要是STM32H750给ESP32长期发数据的情况下发生：步骤如下：平板给esp32发数据：PagePara=0x06EAFF00。 esp32解析成功输出[0x06 0xEA 0xFF 0x00 ] stm32H750发来数据：FE 03 00 C8 00 02 51 FA（Modbus） esp32回复stm32H750数据：FE 03 04 06 EA FF 00 95 B0（Modbus） Stm32H750 将长期发送类似下面的数据 FE 10 00 EA 00 06 0C 00 04 A8 5D 00 00 00 2A 00 07 00 4C 7E C1 其中可能还会收到平板发来的WF=？指令，这是esp32只需要回复WF=OK 一般收到FE 10 00 EA数据5-6条时，就一定发生Task watchdog got triggered.故障，以下就是这个log记录：烦请指导如何定位需要增加延时函数的地方或排查故障的方法。如需要提交代码，请指导需要哪段代码？ I (1481450) WIFI: PagePara=0x06EAFF00,len=19 [0x06 0xEA 0xFF 0x00 ] [udp_socket]:CmdNo=11 Received:[ FE 03 00 C8 00 02 51 FA ] Reply:[ FE 03 04 06 EA FF 00 95 B0 ] Received:[ FE 10 00 EA 00 06 0C 00 04 A8 5D 00 00 00 2A 00 07 00 4C 7E C1 ] I (1482450) WIFI: Received 19 bytes from 192.168.4.2: I (1482450) WIFI: Reply:[ FE 10 00 EA 00 06 75 F0 00 ] Received:[ FE 10 00 EA 00 06 0C 00 04 A8 99 00 00 00 2A 00 07 00 4F 5C 05 ] I (1483050) WIFI: WF=?,len=4 WF=OK I (1483050) WIFI: Received 4 bytes from 192.168.4.2: I (1483050) WIFI: I (1483860) WIFI: WF=?,len=4 WF=OK I (1483860) WIFI: Received 4 bytes from 192.168.4.2: I (1483860) WIFI: Reply:[ FE 10 00 EA 00 06 75 F0 00 ] Received:[ FE 10 00 EA 00 06 0C 00 04 A8 C1 00 00 00 2A 00 07 00 4F C7 C6 FE 10 00 EA 00 06 0C 00 04 A8 F3 00 00 00 2A 00 07 00 4B 8B 64 ] Reply:[ FE 10 00 EA 00 06 75 F0 00 ] Received:[ FE 10 00 EA 00 06 0C 00 04 A9 1B 00 00 00 2A 00 07 00 4E B4 A6 FE 10 00 EA 00 06 0C 00 04 A9 4D 00 00 00 2A 00 07 00 4F A2 C5 ] I (1484890) WIFI: WF=?,len=4 WF=OK I (1484890) WIFI: Received 4 bytes from 192.168.4.2: I (1484900) WIFI: I (1485840) WIFI: WF=?,len=4 WF=OK I (1485840) WIFI: Received 4 bytes from 192.168.4.2: I (1485840) WIFI: Reply:[ FE 10 00 EA 00 06 75 F0 00 ] Received:[ FE 10 00 EA 00 06 0C 00 04 A9 6B 00 00 00 2A 00 07 00 4D 91 65 FE 10 00 EA 00 06 0C 00 04 A9 A7 00 00 00 2A 00 07 00 4F 15 A1 ] I (1486680) WIFI: WF=?,len=4 WF=OK I (1486680) WIFI: Received 4 bytes from 192.168.4.2: I (1486680) WIFI: E (1486850) task_wdt: Task watchdog got triggered.

答案对人有帮助，有参考价值 0 "Task watchdog got triggered" 是指任务监视器（task watchdog）被触发，通常是因为某个任务没有在预定的时间内重置监视器。这可能是由于任务在执行过程中被阻塞，或者任务处理时间过长，导致无法及时重置监视器。针对你的问题，以下是一些可能的解决方案： 1. 优化任务处理时间：检查ESP32的任务处理逻辑，确保任务能够快速完成。如果任务处理时间较长，可以考虑将任务分解为多个子任务，或者使用中断来处理数据。 2. 增加任务优先级：如果ESP32在处理STM32H750发送的数据时，任务优先级较低，可能会导致任务被其他高优先级任务抢占。可以尝试提高任务的优先级，确保任务能够及时执行。 3. 使用中断处理数据：如果ESP32在处理STM32H750发送的数据时，任务被阻塞，可以考虑使用中断来处理数据。这样，当STM32H750发送数据时，ESP32可以立即处理，而不会阻塞其他任务。 4. 调整任务监视器超时时间：如果任务确实需要较长时间来处理数据，可以考虑增加任务监视器的超时时间。这样可以避免任务监视器过早地触发。 5. 检查数据接收和发送逻辑：确保ESP32在接收和发送数据时，逻辑正确。例如，检查Modbus协议的实现是否正确，以及数据包的格式是否符合预期。 6. 使用调试工具：使用调试工具（如ESP-IDF的调试器）来跟踪任务的执行过程，找出导致任务监视器触发的原因。这可以帮助你更好地理解问题，并找到解决方案。 7. 考虑使用RTOS：如果ESP32的任务较多，可以考虑使用实时操作系统（RTOS）来管理任务。RTOS可以帮助你更好地管理任务的优先级和调度，从而避免任务监视器触发。 8. 检查硬件连接：确保ESP32和STM32H750之间的硬件连接正确，没有导致数据传输错误或延迟。通过以上方法，你应该能够找到导致"Task watchdog got triggered"的原因，并采取相应的措施来解决问题。
