Can't use BOSSA to update and fix Duet3 board

ahwitmer

One thing, it updated correctly, verification was positive.
After restart however, the RPI still mentions:
"Failed to connect to Duet3"
"DCS is unavailable"

I restarted the system, no change
Surface disconnected and restarted, no change
reset the Duet3, no change
Connecting surface, Duet recognised but Bossa verify does not work.
repeated the erasing and updating, still the same problem

Set-up
Installed bin: 3.2 beta 2 (Duet3Firmware_MB6HC)
3D printer: Duet 3 and 3 expansion boards 3HC (Januari 2019)
RPI 4 Model B - 4GB

@ahwitmer Try reflashing your pi with a fresh DuetPi image.

https://duet3d.dozuki.com/Wiki/SBC_Setup_for_Duet_3?revisionid=HEAD#Section_Step_1_Flash_the_image_file

And then since you've got a beta on the board you'd have to add the unstable update repository on the pi.

https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Software_Installation

That is, of course, assuming you intend to do beta testing. If you want to stick to the stable branch you'd want to stick with 3.1.1

is the erase jumper still in place? and what does the board identify as - duet or bossa on device manager?

ahwitmer

@bearer The erase jumper has been removed after erasing. After erasing and removing the jumper, my Bossa program says nothing at all. My laptop confirms to see Duet3 after connecting cable again. I can choose a com port. The com port only appears when the laptop is connected via the PI. When updating it shows the prgress monitor from 0 to 100%. When performing the verify it confirms successfull update. I switch off the printer, disconnect the cable and restart the printer. After this it says not to be able to connect to the Duet3. Resetting or restarting has no effect.
Then trying to perform a verify with bossa again after connecting laptop. Verification is not possible

as what? a duet or a bossa port?

ahwitmer

@bearer no just as Duet (from the tasktray), the Bosa program does not say anything. The program has only a com port available when plugged in.

I thought to take the latest version not necessarily Beta testing the firmware.
I will use to the stable version 3.1.1. I will try that one first. If that does not work I will take the reflash of the pi sd

@Phaedrux @bearer
First trial, version 3.1.1 downloaded
Jumper on duet3
switch printer on
after starting up, switch printer off
jumper removed and switch off
Printer switched on, wait for startup
connect laptop to printer via duet3 USB connection
Bosa makes com 4 available
Checked: Erase all, boot to flash and lock
Update 711 pages, verify okay
switch off, disconnect laptop
switch on, "failed to connect Duet3"

I will now download the alternative duet pi image to the pi sd card.

Phaedrux

@ahwitmer Are you powering the duet and Pi separately?

ahwitmer

@Phaedrux @bearer
It finally worked !
Updating the Pi sd card to the latest version, finally did it. It is connected to the duet3 again, great!

Also surprisingly this time my pi asked me to update the firmware something it did not do before. So now I upgraded the Duet3 to version 3.1.1 and updated the RPi too.

Now updating firmware of the three expansion boards

Thanks for the help

ahwitmer

@Phaedrux No the RPi is powered via the duet card. I have a separate power available but until now, it was not necessary to use it.

Ultimately for the problems I encountered it is not an issue!
