First you need to open the case and connect to the serial port pins.
After that, your computer is the tftp server with the IP address of its Ethernet port set to 192.168.1.1. You could pick a different address if you change the commands you enter over the serial connection to the bootloader accordingly.
Yes, modem is connected to the UART and all commands have been entered and saved on to the modem, exactly as they appeared in the guide on page 1.
It's the image transfer I'm having issues with, once I've executed the run update_openwrt command, Kitty just shows T T T T then times out and starts 'waiting' for the file again. It's as though it can't communicate with the Tftp tool.
The guide for the Tftp tool states, to use the Tftp client (as seen in image) I only need to enter the Host name and the file name (path seen in image) and click 'Put'.
So to avoid ambiguity:
1. Should I be using the Tftp client? Or should I use the Tftp server?
2. If it's the client, what should I enter in:
a. The Host field?
b. The Local file field?
3. Where should I save the image file on my PC? Does it matter?
4. If it's the Tftp server I should be using, what values do I need to put in which fields?
5. Do I need to manually set the IP address of the ethernet port on my laptop?
Thanks in advance,
