General Update Process

Updating the firmware via TFTP is intended for the initial setup of the phone or for situations when there is no other way to get the phone working again.

  • While the snom 3xx and 820 are booting, the text To update by TFTP, press any key: can be seen on the phone's display while the TFTP update application is counting down 3 - 2 - 1; during the countdown, press any key on the alphanumeric keypad to initiate the TFTP update. If the TFTP update prompt is not shown, the phone needs to be power cycled, i.e., turn the power off and then on again. Note: On the snom821, snom870, and 7xx phones, the TFTP update prompt will not usually appear at bootup. Instead, disconnect the phone from its power source and press the pound (hash) key. Keep the pound key pressed while reconnecting the phone to its power source and during the reboot until the TFTP prompt appears on the display. (See Recommended Update for snom870 using Pumpkin for exact details)
  • The phone then asks for the phone’s and the tftp server’s IP addresses, a network mask, and a default IP gateway. If the phone and the tftp server are in the same subnet, only the IP address and the tftp server need to be entered.
  • When you put the binary image in the tftp server directory, make sure that it is renamed to “snomXXX.bin”, replacing XXX with the model number, e.g. 320 for snom320. The size of the file is typically 1-2MB. For the snom820 the recovery firmware image has to be renamed to "snom820-r.bin".
  • Images contain a CRC check. If the download process fails for any reason, this CRC check will also fail and the TFTP update application will refuse to erase the application firmware flash section. Otherwise, the TFTP update application will start to erase the flash and to write the image. This process takes approximately one minute.

Note 1: Updating the firmware with the TFTP update application also erases the settings in the flash. This means that all previous settings are lost and the phone does not know even its own identity.

Note 2 There is a Problem with the TFTP update when using certain types of NIC. These problems may occur when the following NIC is in use: Onboard "NVIDIA nForce Networking Controller" of "AsRock AM2NF3-VSTA Mainboards" with nForce-3 Chipset under Windows XP Pro.

Using snom ONE as TFTP Server

If you have a snom ONE server, you can use it as TFTP Server instead of the Pumpkin application. Just create a directory named tftp (using this directory name is important) in the snom ONE default directiory (Program Files/snom/snomONE in Windows or /usr/local/snomONE in Linux), then place the binary file in the tftp directory. Then use the instructions above for the TFTP update.
