@Danal said in Duet3 6Hc + Duex 3Hc with Raspberry 3B+ Wiring Check:

I can't see the jumpers for you Pi power, there is a yellow cable crossing in front of them. Double check them per the wiring diagram.

INT 5 EN and 5V TO SBC are bridged so that the SBC gets the power from the Duet.
Thanks, so i will plug it in and make a Duet Pi upgrade via sudo apt-get update / upgrade from its Screen, Keyboard and Mouse which are plugged in.

@bearer
It fails to connect longer.
I just followed the instructions and gave it a Reset with a jumper on erase. Any else i could do?
Can't I run it from its own Micro SD with its firmware and remove the Pi?
The powered usb Hub didn't help at all to flash it from a PC. I think 5 Volt on its output is still to low and it must be a usb 3 Hub with quick charge function which are quite expensive.

@bearer said in Duet3 - firmware update with RPi:

it is possible there is something wrong with the board, but thats less likely as it was responding to dcs for the update.

you're connecting the micro usb port of the duet 3 to one of the full size usb b ports on the pi? the pi doesn't need drivers to see the serial port, which is why its often a better alternative to windows.

you can install lsusb with sudo apt install usbutils but it should be present, and it most likely won't show anything of interest as the pi isn't detecting the duet.

dmesg | tail -n 20 may be more relevant, shortly (a second or two) after plugging the usb cable in the duet.

K, Thanks. I will sort that out tomorrow.

@Phaedrux said in Duet3 - firmware update with RPi:

Pretty much any cheap usb hub would do. Also try other ports, or a different PC or laptop.

Seems not. Same issue like you have to use a USB Type C Charger to power up the Duet and RPi at the first Preconfig.
My new USB Power Hub with Power Plug makes no difference but seems to be USB 2.1 and has to low Voltage Output.

@Flex3D said in Duet3 - firmware update with RPi:

what did you mean with lsusb? Command not found.

it just lists the usb devices on the pi (to be run in ssh shell or terminal. but as long as the script said it couldn't find /dev/ttyACM0 then odds are its a connectivity issue

I bought jesterday a new usb type B Cable so there should be no reason for. Else ones flying around here aren't working too.

@bearer wget https://pastebin.com/raw/Wa1kYf3G -O - | tr -d "\r" | bash was written to stdout, than i've made a reboot. The board fails to connect to DCS like before
By the Way, I bought a USB Powerhub which made no difference

sorry, i was in the wrong topic thread searching for the command wget.

@Phaedrux said in Duet3 - firmware update with RPi:

Nothing shows up in device manager?

Do you have a USB hub, preferably powered, to put between the pc and duet?

No, do you have a link to a good powered USB Hub?
Can't i get these firmware elsewise on the Duet? I i will try tomorrow those Command from @bearer with a erased Board if that may help.

@bearer said in Duet3 - firmware update with RPi:

@Flex3D looks like you're still on the 3.0-beta12 the board likely shipped with, and its probably easier to connect the Duet3's micro USB port to the Pi and run the Bossa update, no need to disconnect the ribbon cable. The alternative would be to try and update to 3.0, them 3.1.0, then 3.1.1.

Seeing as you have functioning firmware (responds to M115) running the command below should send the command M999 P"ERASE" command to the duet and start bossa to flash the firmware found in the reprapfirmware package.

(or if you have the Duet connected to the pi via USB just run wget https://pastebin.com/raw/Wa1kYf3G -O - | tr -d "\r" | bash)

or follow the documentation.

ref update via usb https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Updating_Duet_3_main_board_firmware

I bridged the erase function like told in dozuki to reset it first and gave it a reboot. Than i connected the duet to my PC and it now has issues to identify the duet board itself. I bought a new usb micro cable too, to be sure but it's not working at all. Bossa shows me an error.

At least the blinking red light is off now but it's not possible to flash anything with bossa at the PC or to enter any G-Code...

i still have the same Fault. I was just using sudo apt-get upgrade and update. The Flash fails and now i'm a bit curious about if i need to make a hard reset with the Jumper, unplug the ribbon cable to the Pi, take a other usb to micro usb as a connection to the Duet micro usb port?
Bossa is already installed on the Pi Image.
When i will make the Reset, the ribbon cable must be unplugged from the Pi to the Duet and than i can power it like usual from the VIN, make the reset and after with the USB to micro USB cable i should flash it?
Sorry this is a bit wired for me and i'm stuck there before the sudo update and upgrade it seems to work like normal and now it doesn't read out any sensors.
It should not be possible to disassemble the whole Board again to just make a firmware upgrade and to reassemble it any time or is it?
