I’m beginner in FreeRTOS…  
Could some one tell me which parameters in FreeRTOS do I need to increase/decrease for stop writing me constantly “Stack overflow” on  
Task Name “EthIf”? see my screen [77 — ImgBB](https://ibb.co/hZ8WpGQ)

The stack size is a parameter passed into the function used to create the task. See the xTaskCreate() and xTaskCreateStatic() API documentation on the [FreeRTOS.org](http://FreeRTOS.org) site. I would post a link but am not on my computer at the moment.

In my case I adjusted stack size manually.  
I adjusted on STM32CubeMX but It doesn’t work.  
because stack size code was in user code block.

----------------before----------------  
**#define INTERFACE\_THREAD\_STACK\_SIZE ( 350 )**

_/ USER CODE BEGIN OS\_THREAD\_NEW\_CMSIS\_RTOS\_V2 /_  
memset(&attributes, 0x0, sizeof(osThreadAttr\_t));  
attributes.name = “EthIf”;  
**attributes.stack\_size = INTERFACE\_THREAD\_STACK\_SIZE;** _← increase this value_  
attributes.priority = osPriorityLow;  
osThreadNew(ethernetif\_input, netif, &attributes);  
_/ USER CODE END OS\_THREAD\_NEW\_CMSIS\_RTOS\_V2 /_

----------------after----------------  
**#define ETHIF\_STACK\_SIZE 1024**  
/\* USER CODE BEGIN OS\_THREAD\_NEW\_CMSIS\_RTOS\_V2 _/  
memset(&attributes, 0x0, sizeof(osThreadAttr\_t));  
attributes.name = “EthIf”;  
 **attributes.stack\_size = ETHIF\_STACK\_SIZE ;**  
attributes.priority = osPriorityLow;  
osThreadNew(ethernetif\_input, netif, &attributes);  
/_ USER CODE END OS\_THREAD\_NEW\_CMSIS\_RTOS\_V2 \*/
