DCS Not starting (Could not connect to Duet)

A Former User

can you connect using the micro usb cable and run M115 if it says 3.0beta12 or something you need to update the firmware on the duet manually as the apt upgrade skips a step.

if your pi has a internet connection i found it easiest to just build bossa and do the upgrade from there as windows & osx can be subject to a bug. I've put together a script that attempts to do everything with a single copy/paste command if you want to try that wget https://pastebin.com/raw/Wa1kYf3G -O - | tr -d "\r" | bash (needs the Duet's micro usb port connected to the pi)

manual instuctions if you prefer: https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Updating_Duet_3_main_board_firmware

sugget the duet micro usb isn't connected to the pi or the cable isn't working properly?
(maybe i should move that test up to the top, good idea)

connect the pi or try another cable? you can run lsusb and just see when the output changes, then run the script again

pi@duet3:~$ lsusb

Can I have both the USB plugged in from the Duet to the PI and Duet VIN power at the same time?

if the ribbon cable is connected then adding the usb cable isn't going to make any difference, but you can also do it without Vin if it feels safer.

bcrazycramer

I found another usb cable:

pi@duet3:~$ lsusb

Trying it again.

this was the duet, so better cable, presumably that changed to something like Bus 001 Device 008: ID 03eb:6124 Atmel Corp. at91sam SAMBA bootloader

but either there is still an usb issue or the beforementioned bug is affecting the pi as well. I'd maybe try using the manual procedure from windows and see if its the same. if still troublesome, try yet another cable.

Same thing.

Verify:

A Former User

other options include SAM-BA software or atmel studio. you could also find it works with another computer and/or usb cable.

bcrazycramer

I got it to switch to COM4 and got farther:

A Former User

thats a bit fishy; sounds like the connection was broken when it was COM3 and because the software still were using COM3 it had to be assigned to COM4 when it reconnected (or do you happen to have two separate Duet3 boards connected to to different USB ports?)

edit: I'd focus on trying other usb cables/usb ports based on that

bcrazycramer

I will give all this a try tomorrow. Thanks!!

bcrazycramer

I'm having the same issue this morning using a Dell Laptop. The Duet 3 shows up as Com 3 in Device Manager. Bossa Program Port (Com3). When I try to verify I get the SAM-BA operation failed.

bcrazycramer

With another USB cable when I Verify I get Verify failed with page errors and byte errors.

A Former User

given the board was flashed and tested before it shipped I'm inclined to think the issue is the usb cables still. its not the first time someone have tried 3 and 4 cables before getting a new one and then succeeding.

alternatively trying sam-ba or atmel studio instead of bossa.

I wasn't clicking write and then verify. My bad.

Current status after the write and verify:

How can I get an original 26 pin to 40 pin ribbon cable for the Duet 3 to Raspberry Pi?

(but it's not going to affect the issue at hand)

bcrazycramer

Why do you say it won't help?

A Former User

The Pi seems to indicate the Duet is connected but not responding properly.

Are you able to connect to the usb serial console and execute M115 to show which version of the firmware is running on the Duet now?
