NUCLEO-H723ZG Ethernet LWIP

hello all
i am having stability issues with a sample code that uses ethernet with lwip and freertos.
practically the operation is unstable, after a few resets it works but then hard faults appear:

HardFault_Handler() at stm32h7xx_it.c:88 0x8000f88
<signal handler called>() at 0xfffffffd
__ISB() at cmsis_gcc.h:935 0x800d16e
SCB_InvalidateDCache_by_Addr() at core_cm7.h:2,528 0x800d16e
HAL_ETH_RxLinkCallback() at ethernetif.c:957 0x800d16e
HAL_ETH_ReadData() at stm32h7xx_hal_eth.c:1,104 0x8005a9c
low_level_input() at ethernetif.c:488 0x800cbe0
ethernetif_input() at ethernetif.c:514 0x800cc1e
pxPortInitialiseStack() at port.c:214 0x8010740

 

how can i solve this problem?
I use CubeIDE MX Version: 1.16.0
Build: 21983_20240628_1741 (UTC)

below is the code

So when you enabled the D cache the fault does not occur. That's good.

Now to the ping. If you have H723 Nucleo without any modification: you can open a bug against the example (github issue).

Check the eth connection. Recommended to use a 10/100 hub and a private network segment for first test. Not a cross cable to a computer. Do not connect to shared/workplace network.

In your init code (lines 106-140) the cache is not enabled (or I cannot notice it). There's a bug (?) in H7 library that SCB_InvalidateDCache_by_Addr() can crash if the cache was not enabled. So either enable the cache or don't call SCB_InvalidateDCache_by_Addr, or handle and dismiss the exception.

 

hello
I took inspiration from an example provided on the st repo.

https://github.com/stm32-hotspot/STM32H7-LwIP-Examples/tree/main/STM32H723_Nucleo_ETH

I tried to enable I and D cache from the Cortex M7 settings and by doing so the board does not even respond to ping, so I had to disable them again.

 

Why?
