  • Can't TFTP new firmware to XPort Pro

    I've been able to install the SDK, make changes through menuconfig, and build a new set of image files... Now I'm trying to TFTP my updated firmware to my XPort Pro, but I'm getting errors saying:

    ICMP : Port Unreachable
    TFTP could not make connection to server.

    I've set my dBUG configuration to match what's shown in section 3 of the user guide, and I've got my TFTP server running with the image loaded into the correct spot on my host. I've turned off the firewall on my host, and I'm able to ping the XPort. I can see the TFTP requests going out over the network through Wireshark... it looks like the host cannot reach port 69 on the XPort.

    My dBUG settings are identical (other than IP and file location, mine is /tftpboot/image.bin) to what's listed in this thread:

    XPort Pro Linux does not have TFTP enabled.
    Typically during development, you would post your new image to /tftpboot on your development platform, and have the XPP use tftp (from dBug) to fetch it.
    In which case, the XPP is the tftp client, and your development system runs the server.

      This was an issue with the TFTP server running on my host machine. I'd been trying to configure the server through the /etc/default/tftp-hpa file, but creating a file named /etc/xinetd.d/tftp with the following contents solved my problem.

      /etc/xinetd.d/tftp:

      Code:
      service tftp
      {
      protocol        = udp
      port            = 69
      socket_type     = dgram
      wait            = yes
      user            = nobody
      server          = /usr/sbin/in.tftpd
      server_args     = /var/lib/tftpboot
      disable         = no
      }
