After converting LwIP_HTTP_Server_Netconn_RTOS to C++, hangs in Hal_Delay()

Hi,

I was working with LwIP_HTTP_Server_Netconn_RTOS on STM32F469I-Eval board.

I converted main.c, httpser-netconn.c to main.cpp and httpser-netconn.cpp

Was able to compile it successfully, but when I did debug, it hanged at ethernetif_init()->low_level_init()->HAL_ETH_Init() -> HAL_Delay() forever.

Even 'uwTick' from HAL_GetTick() had increased till 16 only and that count stopped there forever.

Will help me great if I get some help on how to proceed ahead? or some pin-points to resolve it out?

Regards,

Prashant

My modified main() is:

int main(void)

{ /* STM32F4xx HAL library initialization: - Configure the Flash prefetch, instruction and Data caches - Configure the Systick to generate an interrupt each 1 msec - Set NVIC Group Priority to 4 - Global MSP (MCU Support Package) initialization */ HAL_Init(); /* Configure the system clock to 180 MHz */ SystemClock_Config(); /* Init thread */#if defined(__GNUC__)// osThreadDef(Start, StartThread, osPriorityNormal, 0, configMINIMAL_STACK_SIZE * 5);#else osThreadDef(Start, StartThread, osPriorityNormal, 0, configMINIMAL_STACK_SIZE * 2);#endif // osThreadCreate (osThread(Start), NULL); BSP_Config(); /* Create tcp_ip stack thread */ tcpip_init(NULL, NULL); /* Initialize the LwIP stack */ Netif_Config(); http_server_netconn_init(); User_notification(&gnetif); /* Start scheduler */ osKernelStart(); /* We should never get here as control is now taken by the scheduler */ for( ;; );}
