16.4 Boot
Note: Not supported by Ascom.
During firmware start the bootcode calculates a checksum on the firmware to detect if the
firmware is ok. If the firmware checksum is wrong the firmware cannot be started. In this
case the bootcode includes a small version of the firmware, the minifirmware. The
minifirmware provides the IP stack and the Web interface and should be used to flash a
firmware. The minifirmware has a reduced web interface and shows itself as
IPxxx(Bootcode) .
If also the minifirmware checksum is wrong the device enters TFTP mode.
With a Boot Reset, the VoIP Gateway is transferred to Boot mode and the device executes
the bootcode that contains the minifirmware.
