Aktualizacja oprogramowania To upgrade the firmware you'll need a TFTP client. Please use utftp client for Linux, which was tested and works for sure. Other clients should also work. Untar and compile the utftp: tar xvf utftpd-0.2.4.tar.gz We advise to connect the modem directly to the PC, with no other traffic present. Although it's possible to upgrade firmware remotely (over the Internet), it would be easier to see what is displayed on the LCD and access the serial console if necessary. Connect to the modem and enable TFTP access: Tahoe> tftp on Send the 'erase' file (zero-length) to erase the Flash memory: utftp -p 10.0.0.1 erase (replace '10.0.0.1' with modem's IP address) After a few seconds the Flash memory is erased. WARNING: if your modem had firmware version 1.2.8 or older do not power off or reboot the modem until you complete writing the new firmware. It has no firmware at all at the moment and won't boot again. You don't have to care about that with newer versions (1.2.9 and later) as there is always a bootstrap which is never erased and allows a firmware recovery in case of accidental reboot during the upgrade. Send the new firmware under the name 'flash': utftp -p 10.0.0.1 flash t680-1.2.9.bin (yout may need to change 't680-1.2.9.bin' to another filename) You'll see the programming progress on the LCD. If something goes wrong, repeat the procedure by first erasing the Flash and then programming again. Now you can reboot the modem. |
