Starting the DHCP in STM32 demo

[tmanev]

Any idea how to start the DHCP in the lwip demo with STM32 and ChibiOS ?

I added this in lwipthread.c but the program halts somewhere in dhcp_start!

Code: Select all

  netif_set_default(&thisif);
#if LWIP_DHCP
  dhcp_start(&thisif);
#endif
  netif_set_up(&thisif);

Best regards,
Todor

Hi,

I hoped someone could answer, I never did this too, you could try to look for info in the lwIP mailing list.

Hmmm I also never used DHCP - but there is a note on the lwip wiki:

This example assumes static IP, but the final netif_set_up could be replace by dhcp_start or autoip_start (see Network interfaces management for more information).

Maybe you have to remove the call to netif_set_up?

Also:

When calling from other threads, use the netifapi_dhcp_*() functions defined in the api-module netifapi.c.

So dont use dhcp_start directly.

Thank you, netifapi_dhcp_start() is working for me.
