When using any of the IP binding functions (ipcfg_bind_staticip, auto or DHCP) i don´t get a result, the system gets halted there, waiting for the function to finish ( it can be with an error or with the binding done succesfully) . This does not happen every time, but very frecuently. The code im using is the following ( the ip config and binding its highlighted in the end ) ( sorry for the comments in spanish , im from argentina ) :

void main_task (uint32_t initial_data)

{

IPCFG_IP_ADDRESS_DATA ip_data; //Estructura de datos de ip.

_enet_address mac_address; //Definition for ENET six-byte Mac type. Vector de 6 uchar.

uint32_t error; //Captura código de error

uint8_t lastIp[4][4] = {0}; //Almaceno últimos valores. 0: Ip Servidor. 1: Ip Frdm. 2: MaskFrdm. 3: GtyFrdm.

uint8_t verparamIp[4][4] = {0}; //Idem anterior pero utilizado para el comando verparam. Así si estoy cargando IPs y en el medio quiero ver parámetros no sobreescribe los valores ya cargados.

uint8_t estampa[8] = {0}; //Buffer para escribir en pantalla luego de un itoa

uint32_t lastIpaddr[4] = {0}; //Buffer donde se guardan los IPADDR luego de una leerIPdeFlash()

uint32_t * checkIP = BASE_IPS_FLASH; //Dirección base 0xFB000. Se usa para revisar si la flash está vacía

uint8_t i;

uint16_t tiempo_poleo; //Almaceno el tiempo de poleo

Is anyone else having the same problem ? i dont get an error code , so could it be a problem of my router ?

Hola Javier,

Could you please let me know the MQX version you are using??

Hi Javier,

I have not used that specific API call.

I have in the past called SNTP_oneshot() successfully.

Attached is my relevant code from long time ago when I was playing with MQX3.7 or MQX3.8.

Generically it assumes good network connection and a known good NTP server IP address to use.

If the SNTP_oneshot() fails, then a default time is set.

Hope it helps.

Regards,

David

Hello David,

If i use this function , i do not have to use al the ip functions ? . This funcion also manages the configuration of the ip interface ?
