    on openwrt, the mtd command is used.
    on dd-wrt. the write command is used.

    as both seem to be missing in toastman-mod, what's the procedure if any?

    One question, why do you prefer flashing from command line ? Is it more failsafe ?

    This is a script I use to do my firmware updates. It clears nvram and writes a new firmware file (looks for file called /tmp/fw_*.bin). I dove into the GUI source to see how it did it and tried to mimic it the best I could. It works for me but no guarantees, it may turn your router into a flower pot.

    echo About to clear all settings and write new firmware from file: $FIRM
    echo Hit return to continue or ^C to cancel
    echo Waiting for services to stop.
    nvram set action_service=upgrade-start
    sleep 1
    kill -s SIGUSR1 1
    while [ "$(nvram get action_service)" ]; do echo -n .; sleep 1; done
    echo Services stopped.
    echo Clearing all nvram settings
    mtd-erase -d nvram
    echo Writing firmware $FIRM
    nohup mtd-write -i $FIRM -d linux &
    while [ "$(pidof mtd-write)" ]; do echo -n .; sleep 1; done
    echo Flash finished.  Rebooting...
    sleep 1
    Couple things to note. I'd origionally tried to use the mtd-write commands directly but was unsuccessful without stopping the services first. Also, for some reason I had to clear nvram then flash the firmware, it didn't seem to erase nvram if I did it after the firmware write even though that's how the GUI does it.

    Happy flashing.

    ah so it is possible. thanks a lot for that script.

    It is more failsafe, especially over wi-fi since the firmware gets flashed from the firmware's RAM and the firmware usually gets grabbed with wget. in fact with dd-wrt, flashing new firmware with the command line is the recommended way to do it over wifi. and also on dd-wrt, i do it since there is a bug where the nvram does not get cleared even with the "Reset to Default Settings" option selected. Just a lot easier.

    i'm trying this on a different router actually. but yeah i guess it's a possibility.
