Lose Connection with Duet 2 WiFi after flashing

[armysolo]

I was having issues with Moonraker so I decided to create a new Klipper USB(I like to use USB drives because their faster and more stable than SD cards). I have a RPI 4 8gb, 32gb USB 3.1 flash drive and Duet 2 WiFi. I used the kiauh.sh script to install Klipper, Fluid and Moonraker.

ls /dev/serial/by-id/* /dev/serial/by-id/usb-03eb_6124-if00

I'm able to flash the Duet but after flashing it seems like the board becomes locked. When I re-run ls /dev/serial/by-id/ I get an error for "ls: cannot access '/dev/serial/by-id/*': No such file or directory". If I erase the flash on the Duet the RPI can communicate with it again. I've tried reflashing the Duet and the RPI many times but I'm not sure what else I can do to fix this.

After swapping USB cables and re-flashing this is what the output is.

It seems the USB isn't recognized after flashing the Duet and RPI MCU and reboot.

[armysolo]

It seems it's an issue with Klipper. I've tried cutting the 5v wire on the USB to ensure the Duet isn't being powered from the RPI.

I've tried with 3 different Duet boards and 2 different RPIs along with trying to manually flash with my PC using Bossa. Every way I've tried I get the same result. The board cannot communicate once it's flashed. But if I erase the firmware it can communicate.

[Sineos]

Try this approach: https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_All_other_Duet_boards

[armysolo]

I've already tried that

[zueski]

I am having the same issue on a fresh install on a new pi4 with the latest on debian. I had a working install on a different pi that will not work now even after reflashing without rebuilding. The interesting part is the serial ID changed from:
/dev/serial/by-id/usb-Klipper_sam4e8e_00313753595252533136303532303436-if00
to a non-working:
/dev/serial/by-id/usb-03eb_6124-if00
I have not been able to get it back up after the first flash on the latest commit from Nov 21

[p5y]

I am in the same boat as above.
Was running 0.9.1-something before, that worked as intended.
Created a fresh raspbian-bullseye SD and used kiauh to set things up. I was able to see the Duet when using raspbian buster + klipper 0.9.1-something firmware, but after flashing the new firmware the board wouldn't boot properly.

I tried erasing by jumper, and also flashing the firmware with bossa from windows. This did not help.
Going back to the old rpi SD and flashing the Duet would fix things.
Switching to a SKR mini e3 and things ran in no time with the latest klipper.

Unfortunately I don't have the time nor tools to debug the issue right now.
Hopefully this info will help someone along.

[p5y]

I'm not sure how to approach debugging this board. How do I easily debug the code without JTAG? I can't find anything in the klipper developer docs or Duet wiki that can help me along either. @KevinOConnor can you maybe give me some pointers?

Stepping through klipper revisions to see where it breaks is a fallback, but that's a tedious job.

[p5y]

I played with this issue a bit this weekend.

• Rolled back to master branch nov19 on rpi4/raspbian buster, flashing works and can connect to Duet2 with klipper.
• Setup a dev environment on Ubuntu 20.04 with latest klipper master, flashing works and can connect to Duet2 with klipper.
  I'm not exactly sure what is going wrong here. It seems raspbian bullseye is somehow involved. Ubuntu 20.04, however, is also technically bullseye.

[danielschramm]

Hello,

I also like to confirm this issue in a similar setup.
I had to move to RPI with USB Boot - latest Raspbian this week and I also have Issues.
(Before used Banana Pi with Armbian with Klipper 0.8 or so.)

Board reset to bootloader mode via Erase jumper is OK:

usb 1-1.4: new full-speed USB device number 43 using xhci_hcd
usb 1-1.4: New USB device found, idVendor=03eb, idProduct=6124, bcdDevice= 1.10
usb 1-1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
cdc_acm 1-1.4:1.0: ttyACM0: USB ACM device

Flashing via make flash works without issues.
And than I just get an error:

usb 1-1.4: new full-speed USB device number 59 using xhci_hcd
usb 1-1.4: unable to read config index 0 descriptor/all
usb 1-1.4: can't read configurations, error -110

I Just tried to switch to Release 0.10.0 and 0.9.1 and they show exactly the same behavior.

[danielschramm]

I just repeated everything with Ubuntu 20.10 on the same setup and everything is working as expected .
So it really seems that the build process of the duet2 firmware is just failing on the current raspbian.

[github-actions]

Hello,

It looks like there hasn't been any recent updates on this
Klipper github issue. If you created this issue and no
longer consider it open, then please login to github and
close the issue. Otherwise, if there is no further activity
on this thread then it will be automatically closed in a few
days.

Best regards,

[Zodiak1993]

I have the same problem with a Duet Wifi. Really dont know what to do now...Using Pi Os Lite with Kiauh - tried it 2 times with a clear installation.

@Zodiak1993 see the reply just above by @danielschramm

[Zodiak1993]

Sorry I am new to Linux and Raspberries - Ubuntu is an alternative to PI OS Lite?
Do I have to flash the board with Ubuntu and then install PI Os Lite again? Or can I stay with Ubuntu?
Why is this happening, that the build process fails ?

[Sineos]

Yes, Ubuntu is another Linux OS and can replace PI OS.
Reason why this is happening is not clear. As Klipper is depending on certain packages that come with the Linux OS, there might be some unwanted interaction.

[Zodiak1993]

So for everybody - I could solve it with the "Mainsail OS"
https://docs.mainsail.xyz/setup/mainsail-os

Thank you for your support.

[Sineos]

Topics seems concluded. Apparently some OS issue and not depending on Klipper.

[ccollinscj]

The problem still exists.

Had this same issue. Could not get a working setup with the latest Bullseye version of Raspbian. Using MainsailOS , which uses Buster, works fine.

[DefektSan]

Actual problem.
When compile fw for SAM4E8E mcu in Debian 11 Bullseye, mcu does not stars and still place in DFU mode.
Fw compiled in Debian 10 buster works normal.

[gjsmo]

@Sineos Can this issue please be re-opened? I can reliably reproduce this on a brand new installation of Debian 11, with only Klipper installed. This is the latest version of Raspberry Pi OS, so it's not a particularly unique setup. Yes, it does change based on OS, bu that isn't evidence that the OS itself is the issue.

[bwright85428]

eems concluded. Apparently some OS issue and not depending on Klipper.

@Sineos
"Apparently some OS issue" the latest version of Raspbian? So Klipper isn't supported on the latest version of Raspbian?

[AlexTOOT]

I got same issue on Debian11 using bigtreetech CB1 and Duet2 wifi.
before flashing, it shows up as usb-03eb_6124-if00,
after flashing, duet goes offline, can not find anything in /dev/serial/by-id
switching os version do solve the problem but still wanna fix the issue

[viesturz]

Still a problem.

[underpk]

Anyone know how to solve this problem? I just have the same issue.

[Sineos]

See https://klipper.discourse.group/t/duet-2-firmware-compilation-broken-on-debian-11/4762/

Only known fix is to use a different Linux version for compiling and flashing

[nzidol]

hmm tried mainsailOS 1.2.1; now also bullseye based and fails with same issue

[lesaux]

Sep 11 2023, I needed to use the ubuntu-server 20.04 image to be able to flash my duet2 wifi + duext5. Tried raspian buster-lite, mainsailos and neither would work.

[DefektSan]

Tried raspian buster-lite, mainsailos and neither would work.

You need use raspberry Pi OS Lite (Legacy) on Debian 10 (buster), on this version firmware compile correctly and work fine.
