Necleo-STM32F767ZI board fails on example "LwIP_HTTP_Server_Netconn_RTOS"

Hi,

I just bought a Necleo-STM32F767ZI board, and downloaded the example "LwIP_HTTP_Server_Netconn_RTOS" in CubeIDE, and made following changes in main.h:

#define IP_ADDR2   3

#define GW_ADDR2 3

As for the board, I did not make any changes on the jumpers.

then built it and ran it, I saw the LEDs changes, but it failed almost immediately after file-download-complete. The following are the texts shown in the console window:

    Hello @Chao 

    I can't find any problem on the message you just shared. The code has been succesfully downloaded and the:

    " Shutting down... Exit."

    Means the end of the download operation.

    For the printf fonction, you can use it on this board since it have a virtual com port. Al you have is to do the necessary coding and configurations.

    Best Regards.

    Is it possible to use printf to print debug messages to the console window in this example?

    The log file looks fine to me.

    > it failed almost immediately after file-download-complete

    In what way specifically did it fail?

    OK, thanks. I do be misled by the message "Shutting down... Exit.".

    Now it works when I comment out the "#define LWIP_DHCP  1"

    I will try to make printf work next.

    Regards
