Duet 3 6HC Rev. 1.01 Faulty

Veti · 30 Nov 2020, 12:25

did you power the pi from its own power source or from the duet?

for the bossa thing. try different usb cables. a lot of cables wont work.

NeueKlasse · 30 Nov 2020, 12:28

the Pi is Powered from it's own 3A Source, The Jumpers for SBC<->DUET are both removed.
Yesterday night i tested a few Different Cables, i didn't believe it...

NeueKlasse · 30 Nov 2020, 15:13

Now i've got the COM Detection on the Windows PC to work.
(another COM Port)
the Problem now is: BOSSA Detected ATSAME70x20 but when i load the
Firmware .bin (MB6HC) Version 3.2beta4 from Github,
select it in BOSSA (+Checkboxed for Erase All - Boot to Flash - Lock)
it Stuck at 0% and nothing more...?! if i disconnect the Board after several minutes
BOSSA Tells me immediately that the SAM-BA Operation failed.
whats the Deal?
i'm a little bit disappointed now.. a 250 € Board and i have to use every trick to get it to work...

Can you try getting the board working in standalone mode without the SBC first?

Were you able to get Bossa to flash the board or not?

Once you're able to get a firmware applied to the board again ( I suggest sticking to 3.1.1 for this) you can try downloading a fresh copy of DuetPi and create a new SD card for the Pi.

Hi, Thank you for your Help!

i tried setting up the DuetPi, it always has a problem to connect to the board while sudo apt-get upgrade (FW Version 3.1.2, 3.1.1...(different Firmwares tested.. Error: no header..)) currently i'm running 3.1.1
i managed to get BOSSA on windows working with a completely new usb cable,
and flashed V3.1.1!!
NOW i can connect to the DWC! Problem now is....

i also managed to upload my saved config files...

Running M122 (in that seconds i have connection..) brings following:

i don't understand why it's always reconnecting.. bad Flat Cable??

Phaedrux · 1 Dec 2020, 17:51

While we look into it I suggest getting setup and running in standalone mode without the SBC connected to confirm the Duet 3 is working correctly and get your config sorted. At that point it may be worth trying to the 3.2 beta release which has a number of fixes for the SBC mode.

Phaedrux · 1 Dec 2020, 17:57

@NeueKlasse said in Duet 3 6HC Rev. 1.01 Faulty:

bad Flat Cable??

That is a possibility. Do you have a usable replacement or the ability to make some jumper wires to confirm this?

NeueKlasse · 1 Dec 2020, 17:59

I already tried the 3.2beta 4 with the same issues, at the moment it seems that's only a problem of the DWC / SBC, the Printer is homing and probing while i get errors on the DWC that i lost connection, and get it back, and lost, and back etc. etc.......

how can i test the DWC while i'm running in standalone mode (SD card in the Duet)?

no i have no Replacement, do you have a pinout diagram of the Cable?

...btw.. the Paneldue is working fine

NeueKlasse · 1 Dec 2020, 18:06

i moved the cable while i was connected,
i've got one new Error that DCS has been stopped, i never got that before,
but it was so unresponsive that i cannot confirm that the cable movement was the problem....

It's a flat ribbon cable so 1:1 across with jumper wires.

The Duet 3 wiring diagram is here: https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram

Here you go for a Rpi-3B+

NeueKlasse · 1 Dec 2020, 18:31

Thanks, i managed to setup jumper wires,
now the connection lost problem comes every second...??!

btw. i'm running on pi4

NeueKlasse · 1 Dec 2020, 18:48

The Duet's running in Standalone mode now, i report if i have issues!
Thank's so far

.. update it's running till now ( 45minutes without any problem)...
i think the DuetPi.. create problems

Phaedrux · 1 Dec 2020, 19:06

So just to confirm, changing to jumper wires has made it worse?

NeueKlasse · 1 Dec 2020, 19:44

@Phaedrux it seems so far...

NeueKlasse · 1 Dec 2020, 20:36

In the main time i setted up the DuetPi with a Fresh image.
10min ago i changed everything to SBC Operation and started the printer,
after everything started up i had the Same issue on the DWC...
connection to duet lost, (no header).. and several seconds later, Connection established... and so on and so on...
maybe it's the Pi itself?! i ordered a new Pi4 anyway...

i don't tried it yet but before if i tried to update the Firmware via pi+ribboncable
the Duet FW gets corrupted and i have to erase all and do the FW over USB..... (see 1. Post)

Phaedrux · 1 Dec 2020, 20:50

Having another Pi available to test with would help troubleshoot the issue.

chrishamm · 2 Dec 2020, 08:53

The symptoms you mentioned sound like there is a wiring issue between the Duet and the Pi. I assume if you look into the DCS log via journalctl -u duetcontrolserver -e you'll see lots of checksum errors, too. If there are no checksum errors, it's probably a good idea to try out a different Raspi.

Just to be sure: You don't use another SPI device with the Pi, do you?

NeueKlasse · 2 Dec 2020, 15:49

Thanks,

the Pi tells following...

i orderer a 40 to 26 Ribboncable from Pimoroni

A Former User · 2 Dec 2020, 16:33

you could try reducing the SPI frequency while waiting for new ribbon cable; /opt/dsf/conf/config.json (or something like that)
