@bearer on windows it shows as com3 bossa port on the Pi it shows -

pi@duet3:~ $

the first instance of lsusb is disconnected and the second the duet id connected it shows 7 usb ports as im using the raspberry pi keyboard but the duet is connected directly to the board!

Maybe I missed it, but which version of Pi is it and how is it powered? If possible, try powering the pi directly from the wall if not already.

@Phaedrux the Pi is a Pi 3b+ it is powered via the duet, i can move the jumper and power externally if you think it will make a difference?

Phaedrux

@jumpedwithbothfeet worth a shot.

jumpedwithbothfeet

@Phaedrux @bearer it sort of worked! I have a low power symbol, but it appears I have access to DWC before I mess up the progress should I sudo update or load my config files?

jumpedwithbothfeet

@Phaedrux so i'm back up and running! however i now have the issue of powering the Pi correctly its externally powered now but i still have the lightening bolt in the corner, my duet has a jumper only bridging INT 5v EN is this the correct way to leave it?

@bearer @Phaedrux @Veti before I forget I just want to say thank you for your help, it is very much appreciated especially as it is something I would of never figured out by myself.

Kind regards Jim

If it showed up as bossa on windows and openmoko/duet on the pi then it wasn't properly flashed before you effectively reset it when moving the usb cable to the pi I reckon.

Bossa is the bootloader.

I would suggest that you power the duet and the pi separately and not one from the other. So Int 5v jumper position.

What other USB peripherals are connected to the Pi?

Am I to understand that you're up and running now other than the lightning bolt?

Originally it was planned to be able to power either direction, but the power draw was spec'ed for a Pi3 with no peripherals, so it can actually end up being easy to overwhelm in practice.

jumpedwithbothfeet

@Phaedrux I only power the keyboard and mouse from the Pi, I used to run a 7inch touch screen via the Pi too but I noticed the duet was sort of glitchy when running it so I stopped using it apart from that the only other usb device is a usb flash drive for file transfer.

thank you for the link I looked on the wiring diagram and the 5v notes but didn’t think to look at the overview! I will power the. Separately from now on, I think the lightening bolt is just my crappy Pi PSU it only has a 2.5amp output, I’ll test that when I hook up a 5 amp buck converter i have and see if it sorts the issue!

@bearer I thought it had loaded correctly write/verify/reset etc, is it still an issue then? Or would the lack of power from the Pi cause bossa on the pi fail to find the board?

if the board identifies as bossa flashing was not a success. (erase jumper left in place or not reset are the common failures)

as long as it identifies as duet (or openmoko on some linux versions) you're ok now

jumpedwithbothfeet

@bearer thank you for the explanation I suspect I may have self induced that a few times these last few days!

@Phaedrux I have just tried my pi on a 5 amp buck converter and powered it up along with the printer, I am still getting the lightening bolt, is it only for the Pi side of the system I.e raspbien/Linux or the duet as well via the ribbon cable if you know what I mean, Unfortunately I don’t have a spare Pi3/4 to swap it out with, I did remove all usb connections and the bolt is still present.

jumpedwithbothfeet

@Phaedrux all sorted it was a cheap usb cable! Thanks again for your help

Phaedrux

I've added some notes to the Duet3 documentation on powering the SBC. When in doubt, power it separately.
