Thanks for getting back to me on this :D

(1) I was attempting to use POE but may try an AC adapter if i can find one lying around. Also, I think when Dan and I tried flashing it last night at the meet-up it was over POE and he was able to get the script to at least start transferring, but he was also using a different usb adapter. My next goal is to find a different usb adapter and try that out.

(2) The usb adapter is a manual one so it's possible something was off with my configuration even though I checked it a bunch of times (though it was pretty late in the evening lol). Shoutout to Max: did you have problems with this adapter when you were using it?

(3) That is a reallllly good question and I didn't even think of that possibility! I'll dig through the meraki docs to see if any mention is made regarding that.

I have no experience yet, only interest (in getting them working ;), but I have a couple of questions:

(1) How are you powering the board--AC adapter or power-over-ethernet? (I'm not sure POE works, would be great to know.)

(2) What sort of adapter are you using (i.e. did you have to manually set the pins) and is it fully and properly connected (physically)?
(3) Does the board need to be set into a particular "flash" mode, as some of the other routers, perhaps by pressing/holding a reset button?

Cheers,
Matt

Hey everyone!

I've been trying to set up the Meraki Sparky board to flash the openwrt code to it, but when I connect the pins and plug in the usb adapter to my laptop and run the meraki-flasher script, I get this exception "SerialException('device reports readiness to read but returned no data (device disconnected?)')" and the green led on the meraki board isn't lit. But $ dmesg | grep tty shows that it's connected.

Does anyone have any ideas as to good way to pinpoint what the issue may be? Not sure if the issue is the usb adapter I'm using or the board itself, but I was going to try buying another usb to ttl adapter tomorrow to see if that helps. Any advice would be awesome!

It was nice meeting you all tonight!
