Good morning, I made a project using stm32f407vet6, configuring the stm32f407vet6 to use ethernet network without freertos, I can ping it and it responds immediately, follow the code:
#include "main.h"
#include "lwip.h"
void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_RTC_Init(void);
/* USER CODE BEGIN 0 */
extern struct netif gnetif;
struct pbuf *p;
/* USER CODE END 0 */
/**
* @brief The application entry point.
* @retval int
*/
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init(); MX_LWIP_Init();
MX_RTC_Init();
while (1)
{
ethernet_input(p, &gnetif);
sys_check_timeouts();
}
/* USER CODE END 3 */
}
but now I want to use freertos and have a UDp server, but when configuring freertos, stm32f407vet6 gets stuck inside MX_LWIP_Init();, the firmware version for STmf4 is 1.28.1, here is the code:
#include "main.h"
#include "cmsis_os.h"
#include "lwip.h"
osThreadId_t defaultTaskHandle; const osThreadAttr_t defaultTask_attributes = {
.name = "defaultTask",
.stack_size = 128 * 4,
.priority = (osPriority_t) osPriorityNormal,
};
/* Definitions for task_2 */
osThreadId_t task_2Handle;
const osThreadAttr_t task_2_attributes = {
.name = "task_2",
.stack_size = 1024 * 4,
.priority = (osPriority_t) osPriorityLow,
};
/* Definitions for task_3 */
osThreadId_t task_3Handle;
const osThreadAttr_t task_3_attributes = {
.name = "task_3",
.stack_size = 1024 * 4,
.priority = (osPriority_t) osPriorityLow,
};
void SystemClock_Config(void);

int main(void)
{

SystemClock_Config();
MX_GPIO_Init();
osKernelInitialize();
defaultTaskHandle = osThreadNew(StartDefaultTask, NULL, &defaultTask_attributes);
task_2Handle = osThreadNew(StartTask02, NULL, &task_2_attributes);
task_3Handle = osThreadNew(StartTask03, NULL, &task_3_attributes);
osKernelStart();
while (1)
{
}
}
