I created a simple program for STM32f407 discovery that has FreeRTOS (10.0.1) and LWIP (2.0.3) in STM32CubeIDE 1.1.0. It uses a task to start LWIP and dhcp and kills the task. It has a software timer that blinks an LED and printf a counter.

My goal is for the ESP32 to be able to send/receive UDP packets via ethernet, but I also need to be able to update the firmware with a web updater OTA. I was able to achieve this while using Wi-Fi, but not while using ethernet.
WebIn my view a crash is a bug, and by using packet filtering you might treat the symptom but not the problem. I would investigate where the crash happened and fix that first. However, lwIP is by design very conservative with its resource usage, and by application likely to be on systems that are constrained in some way. WebThe lwIP core isn't thread safe. If we have to use lwIP in a multithread environment, we should (or HAVE TO) use "upper" API layers (netconn or sockets). When using raw API you need to protect yourself and the core. Sockets generally can't be used by more than one application thread (on udp/raw netconn, doing a sendto/recv is currently possible). …
