Detecting available UARTs

Hi all!!

I’m at the frustrating final stages of my farmbot install - the ever helpful @roryaronson has been helping me by email, but I figured I’d post here so he’s not bearing the load of my own ignorance!! :rofl:

So I’ve got a Farmbot XL 1.7 that’d I’m soooo close to finishing.

First problem was just getting the x-axis to move smoothly without stalling, so I was fiddling with the wheels on that, but strangely I appear to now have some sort of software error.

I’m getting the farmbot failing to boot and sticking at 'Detecting Available UARTs: [“ttyAMAO”] - tried the almighty ‘switch it off and on again’ a few times, to no avail. I’ve re-flashed the microSD card for the Pi and reinstalled the whole thing, but it just seems to get stuck at this stage.

The only thing I could see in the logs was it was stalling on the x-axis a few times (this was me testing it) and then this error cropped up!

Any help, super appreciated!

Just in case it helps, here’s the settings:

Hi @Katie,

The ttyACM0 device comes into being when FarmbotOS detects a live USB connection with the Farmduino electronics.

To begin, I would check/replace the USB cable between the Raspberry Pi 4B and the Farmduino. (does the Farmduino PCB have any lights On ?)

Hey there!

Yes, I assumed as much, so I’ve tried reinserting, trying different USB ports on the RPi and so on (also tried force changing the firmware path too). It was very peculiar that this started happening - it was all fine and I was just trying to move the x-axis, so odd that it’s lost the connection.

The farmduino seems to have lights on, so it’s getting power (tried the reset button too just in case!).

I’ve ordered some little corner USB cables to see if that’s the problem, but it’s quite a puzzle.
Can you SSH into the farmduino at all? (wondering if I can check for life there)

Ok, good.

Yes, I can SSH into my bot, but FarmBot Inc. removed SSH server a while back from production FBOS images. You can certainly see and understand more of the bot’s behaviour from an IEx Elixir REPL on your device.
It’s easy to add SSH back but requires a custom FBOS build.

Ok. It may be best to “cut to the chase” and contact FarmBot Inc. for help . . maybe the Farmduino isn’t totally healthy (?)

Hey ah, ok, fair enough if they’ve locked down.

No worries, I’ve been chatting with @roryaronson already!
