FreeRTOS +LwIP + FreeModbus TCP Hanging

[PNata]

I am using STM32F746ZG Nucleo board and programmed Modbus TCP with FreeRTOS(LwIP). Initially boad report properly to Modbus Master simulator, after ~10 hours or above any time, MCU going infinite loop some exception function like hardware fault etc,

is it suitable for FreeRTOS with LwIP middleware or not?

Could any one share me issue about this

You're going to have to debug it, start by root causing the Hard Fault, perhaps use a routine outputting helpful detail rather than just while (1)​

Hi,

I am try with debug, Hardware fault exception with BFAR is came. i can not identify why it is happen(Compiler time no error & no warning)

when Debug time,

Warning: Stack pointer is setup to incorrect alignment. Stack addr = 0x20013966 

Please give suggestion for any solution
