normally not at all since you place a jumper across the ERASE pins on the Duet 3.

@Veti i did that too several times. when im verifying the image, bossa stops at ~line 1051. if i try to flash with the 3 options aktivatet, bossa crashes 1 second after the write window appears

Veti · 29 Nov 2020, 17:22

can you try a different usb cable?

Frederik · 29 Nov 2020, 17:32

@Veti yes

Frederik · 29 Nov 2020, 17:33

@Veti the diag led is shining when i connect the board without sbc and vin over usb. ThE Light is not blinking. its static

Veti · 29 Nov 2020, 17:39

@Frederik

yes if the firmware is erased, the diag led should be on constant

Veti · 29 Nov 2020, 17:40

some people have had to use up to 18 different cable until they found one that worked.

Frederik · 29 Nov 2020, 17:43

@Veti you are joking, right ?!? 18 Cables....holy...i cant find what the meaning of the static diage led is ?

If the firmware has been erased the DIAG LED will be on permanently.

@Veti Thank You SOooooooOO much for your tip with the usb cable....i tried a 10 year old usb2 dvd cable (with dual A Plugs on one side). After connecting the second the firmware flashed perfektly on the first try ;).

I would be so lost without you guys and this forum

Have a nice Day !

@Frederikfor information purposes:

The cable that did NOT work: brand new Ugreen with 3Meters in lenght.

The cable THAT worked: 10 Year old usb2.0 with dual USB-A Plug on one side.
Like the on the external dvd or harddrives. Lenght ~ 40cm

So, the cable worked. The firmware flash over bossa worked. Also verifying. I did 2 times exact what's mentioned in the getti g startet wiki. I loaded the additional files, flashed a new copy of duet pi desktop on the 16gb card. After that I copied my .g files in the /sys folder on the boot partition together with the 3.1.1 firmware .bin.

After that, I Did all the steps like network, keyboard layout etc. Without any errors.

Even the update at the end + restart showed no errors. Only in the dcs log is constantly starting and stoping with the meassage:

No connection to duet3

Should I do a standalone firmware reset and after that reconnecting the pi?

It seems that the reset button did not reset the board, even if I hold it like 10 seconds

Frederik · 30 Nov 2020, 02:51

I do all the actual test without Vin.
Only connection over usb and wlan

@Frederik said in No Connection to DCS After Update to 3.2beta4:

Yes I would set it up in standalone to confirm that the Duet is working correctly otherwise and see what firmware version is flashed.

Frederik · 30 Nov 2020, 05:32

@Phaedrux Thanks. I will test that later.

@Frederik You did not mention that you changed the package feed from stable to unstable which is a required step if you want to use DSF 3.2-b4 as well. If you don't do that, you'll get the error message you mentioned.

See here for further information.

Frederik · 30 Nov 2020, 19:12

@chrishammyes, i have the unstable all the time.

After i changed to the standalone mode, made the specific sd card + filestrukture, the board accepted the firmware and the diag led is now out . after that i startet a complete new installation with the pi.

this time everything works fine..

The new Visualizer is amazing
Tomorrow i will install and test the new DuetLapse .

But that way did not work at first with the sbc attached.

Thanks for all your help

Regards
Frederik
