Can't set preemption priority for ethernet global interrupt

[AK16]

Hi,

I am making LwIP + TouchGFX project on STM32H750B-DK following the next tutorial:

https://github.com/GrzHeller/STM32H750B-DK_TouchGFX_FreeRTOS_MQTT_Example/blob/main/README.md

When setting ethernet settings in .ioc I can enable ethernet global interrupt, but can't set preemption priority. I'm not sure if this is the problem, but every time I run the program it goes to HardFault_Handler. Does anyone know why it behaves this way and how to solve it?

Hello @AK16 ,

You can set the preemption priority for ethernet global interrupt in NVIC as shown in the below figure 

I hope this help you to solve the issue.
