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.

  • The TFTP update application waits for a short period when displaying To update by TFTP, press any key: 3 - 2 - 1 on booting up, during which the user can press any key to come to the TFTP update screen.
  • It then asks the user for the phone’s own IP address and the tftp server’s IP address, a network mask and a default IP gateway. If the phone and the tftp server are on 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.
