I created my project using lwip_httpsrv_freertos example. I added some own api calls. But sometimes the program reaches BusFault exception and the program hangs. It happens while making api request only and it is totally random. Sometimes the program works for longer, sometimes exception is reached faster and always program counter shows xPortStartScheduler. I attached all information in photo. Sorry for bad photo quality :/
Is it the problem with lwip or FreeRTOS or is it problem with my code?
