RTOS/DK-TM4C129X: Is it possible to assign more than one IP address in RTOS ?

Part Number: DK-TM4C129X

Tool/software: TI-RTOS

Hi,

In my project I use DK-TM4C129X and want to assign two IP addresses to my board the former is for UDP communication and the latter is for logging mechanism I do not want to use UART for this purpose and want to do it with networking. However, I can not find any information about if it's possible or not. Could you please help me about these? Thanks in advance for your answers.

Best Regards.

    Hi,

    We do not have an example illustrating multiple IP addresses on the same interface. However, some community members have achieved a similar goal with the CfgAddEntry() API (see NDK API Section G.2.2). The limitation is that each IP address must be on a separate subnet.

    Please refer to the following post (look for the CfgAddEntry() example):

    https://e2e.ti.com/support/embedded/tirtos/f/355/p/237302/836816#836816

    CI_IPNET NA;
    NA.IPAddr = htonl(0xc0a802c0); // example IP address (192.168.2.192)
    NA.IPMask = htonl(0xFFFFFE00); // example mask (255.255.254.0)
    CfgAddEntry(hCfg, CFGTAG_IPNET, 1, 0, sizeof(CI_IPNET), (UINT8 *)&NA, 0);

    Another suggestion for your situation is to use one IP address and two different port numbers: one for UDP communication and one for logging.
