FREERTOS + LWIP + shared memory

[mosamasa]

Hi,

I'm using STM32H755 nucleo board. I'm having freertos + LWIP on M7 core and bare metal on M4. I'm using TCP command to start some real time test on core M4. I'm using shared memory to trigger test and also transmitting some data back to M7 core. 

I'm having occasional problem. I am getting hardfault on M7 core. I'm looking fault analyzer with following results:

I'm not sure how I can find root cause for the problem? It seems that something goes wrong with tcpip_thread.

Hello,

You need to debug the hardfault: How to debug a HardFault on an Arm® Cortex®-M STM32

Fortunately this kind of fault is very clear. Code in ethernet_input(), precisely at the given address, tried to touch address 0x0FAF0FAF. Debug.
