Hi all,
I'm trying to develop a simple tcp echo application with my NUCLEO-F439ZI. I used CubeMX to configure my board. My app is under FREERTOS using LwIP library. I followed example indications I found but It really doesn't work fine. This is the my CubeMX configuration:
-- CLOCK
-- System base time source
-- ETH
-- FREERTOS
-- LwIP
My code is the following:
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_FREERTOS_Init();
osKernelStart();
while (1){}
}
void MX_FREERTOS_Init(void) {
osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 256);
defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);
}
void StartDefaultTask(void const * argument)
{
MX_LWIP_Init();
tcpecho_init();
for(;;)
{
osDelay(1);
}
}
void MX_LWIP_Init(void)
{
/* IP addresses initialization */
IP_ADDRESS[0] = 192;
IP_ADDRESS[1] = 168;
IP_ADDRESS[2] = 0;
IP_ADDRESS[3] = 10;
NETMASK_ADDRESS[0] = 255;
NETMASK_ADDRESS[1] = 255;
NETMASK_ADDRESS[2] = 255;
NETMASK_ADDRESS[3] = 0;
GATEWAY_ADDRESS[0] = 0;
GATEWAY_ADDRESS[1] = 0;
GATEWAY_ADDRESS[2] = 0;
GATEWAY_ADDRESS[3] = 0;
tcpip_init( NULL, NULL );
IP4_ADDR(&ipaddr, IP_ADDRESS[0], IP_ADDRESS[1], IP_ADDRESS[2], IP_ADDRESS[3]);
IP4_ADDR(&netmask, NETMASK_ADDRESS[0], NETMASK_ADDRESS[1] , NETMASK_ADDRESS[2], NETMASK_ADDRESS[3]);
IP4_ADDR(&gw, GATEWAY_ADDRESS[0], GATEWAY_ADDRESS[1], GATEWAY_ADDRESS[2], GATEWAY_ADDRESS[3]);
netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, ðernetif_init, &tcpip_input);
netif_set_default(&gnetif);
if (netif_is_link_up(&gnetif))
{
netif_set_up(&gnetif);
}
else
{
netif_set_down(&gnetif);
}
netif_set_link_callback(&gnetif, ethernetif_update_config);
osSemaphoreDef(Netif_SEM);
Netif_LinkSemaphore = osSemaphoreCreate(osSemaphore(Netif_SEM) , 1 );
link_arg.netif = &gnetif;
link_arg.semaphore = Netif_LinkSemaphore;
osThreadDef(LinkThr, ethernetif_set_link, osPriorityBelowNormal, 0, configMINIMAL_STACK_SIZE * 2);
osThreadCreate (osThread(LinkThr), &link_arg);
}
void tcpip_init(tcpip_init_done_fn initfunc, void *arg)
{
lwip_init();
tcpip_init_done = initfunc;
tcpip_init_done_arg = arg;
if (sys_mbox_new(&tcpip_mbox, TCPIP_MBOX_SIZE) != ERR_OK) {

if (sys_mutex_new(&lock_tcpip_core) != ERR_OK) {
LWIP_ASSERT("failed to create lock_tcpip_core", 0);
}
#endif /* LWIP_TCPIP_CORE_LOCKING */
sys_thread_new(TCPIP_THREAD_NAME, tcpip_thread, NULL, TCPIP_THREAD_STACKSIZE, TCPIP_THREAD_PRIO);
}
void tcpecho_init(void){
sys_thread_new("tcpecho_server", tcpecho_thread, NULL, DEFAULT_THREAD_STACKSIZE, osPriorityAboveNormal);
return;
}
static void tcpecho_thread(void *arg){
struct netbuf *my_buf;

u16_t len;

/* Process the new connection */
if(accept_err == ERR_OK){
while ((recv_err = netconn_recv(newconn, &my_buf)) == ERR_OK){
do{
netbuf_data(my_buf, &data, &len);
netconn_write(newconn, data, len, NETCONN_COPY);
HAL_GPIO_TogglePin(GPIOB, LD1_Pin|LD3_Pin|LD2_Pin);
}
while (netbuf_next(my_buf) >= 0);
netbuf_delete(my_buf);
}
/* Close connection and discard connection identifier */
netconn_close(newconn);
netconn_delete(newconn);
}
}
}
else{
netconn_delete(newconn);
}
}
}
When I debug, my code always go into static void prvCheckTasksWaitingTermination( void ) function.
Could you help me please? It took me forever.
Thank you.
Regards
