STM32H457I Ethernet, LwIP and SNTP

[QRobe.1]

Hello, I was wondering how to implement a SNTP Client.

I am using the STM32H745I board and I am able to ping through Ethernet, without OS. From what I have understood so far, I am supposed to redefine a macro called SNTP_SET_SERVER_TIME. Am I supposed to this in the file lwipopts.h or sntp.c ? . Then, the prototype is defined in the main.c for setting the time.

In the main.c, three functions are called :

- sntp_setoperatingmode(SNTP_OPMODE_POLL);

- sntp_setservername(0, "pool.ntp.org");

- sntp_init();

And in the main loop, there are two functions called :

- ethernetif_input(&gnetif);

- sys_check_timeouts();

It seems that the prototype of the function is never called, do you have any ideas or advice to give ?

Hello @QRobe.1​ 

1. SNTP_SET_SERVER_TIME should be in sntp.c file
2. Which prototype function you think is not called. Please provide more details about your example so that we can help you
