RA6M4 Azure RTOS nxd_bsd.c raw socket

Hi,

I am trying to use raw socket on nxd_bsd.c, but running into some errors. I can't find the function for _nx_driver_hardware_packet_received_callback and _nx_driver_hardware_packet_send.

Please can someone help me locate where these functions are?

Thanks in advance,

Victor

  • Hello Victor,

    When using Azure RTOS NetX Duo BSD Support stack with all the necessary configuration a folder named BSD in location ra/microsoft/azure-rtos/netxduo/addons/BSD is generated which includes two files nx_bsd.c and nx_bsd.h file. If you will search on these files you will see that: 

    #ifdef NX_BSD_RAW_SUPPORT
    _nx_driver_hardware_packet_received_callback = _nx_bsd_hardware_packet_received;
    #endif /* NX_BSD_RAW_SUPPORT */

    in function bsd_initialize() at line 431.

    The implementation of _nx_bsd_hardware_packet_received() function starts from line 12865.

    Regarding function _nx_driver_hardware_packet_send() ,in the same file nx_bsd.c you will find out that this function is called by function _nx_bsd_hardware_internal_sendto(). The implementation of _nx_bsd_hardware_internal_sendto() starts at line 12681.

    What kind of error message are you getting on your code?

    Hope it helps!

  • Hello IK,

    Thanks for looking into this for me. Your explanation is correct, but the I am having is undefined reference on both _nx_driver_hardware_packet_received_callback and _nx_driver_hardware_packet_send(). 

    _nx_driver_hardware_packet_received_callback error

    _nx_driver_hardware_packet_send() error

    I can not find where these two are defined. Please can you help tell me where they are defined?

    Thanks very much for spending your time to look at this.
