Found the issue. In stop.g I call G28 X which executes homex.g.
It contained G1 S1 Z3 which didn't work because the Z probe was triggerd.
Changing it to G1 S0 Z3 solved this.
Thank You

I configured Cura to send M0 when the print is done. But M0 => stop.g is not executed. But the end-gcode is ignored
I also tried to paste this code in the Cura box for end-gcode same result.
The carriage just stops at the last gcode instruction and the console states that the print is finished. This results in a huge meld pod on top of a print.

Cura 3.5.1
RepRapFirmware for Duet 2 WiFi/Ethernet version 1.21 running on Duet WiFi 1.02 or later

Content of stop.g

I'm not sure about the other config on how to address the second Z motor and set all the parameters.
Can I do Znnn:nnn ? Or do I need to use an other char?

Problem solved!
I found a windows laptop. Did the hole update procedure. Write, Verify all went well. Tried to push the calibration dot still no response.
Turned around the board looked closely. peeled a bit on all the flat cables. Found out that one of the small flat cables in the center of the board was not sitting in the slot but was slipped under the slot. Turned off power, inserted flat cable in the slot. And BOOM the touch screen worked.

Thank you all, dc42, phaedrux, gtj0 for troubleshooting with me.

@gtj0 said in PanelDue is unresponsive after update:

If the verify is failing, you only think you're writing to the board.
Is the board connected to the Duet while it's also connected to your laptop? It's possible there's a ground loop happening which is corrupting the data. Disconnect the panel from everything other than the USB cable and try.

The board is not connected to the duet when I flash the firmware.
Still need to test with an other laptop. So keep you posted.

The verify tool on bossac is failing often. It seems like after the erase and write action the connection drops.

The usb is fine otherwise I would never be able to write to the board.

After I uploaded the new firmware I connected the panel to the duet to ensure there is enough power but the screen remains unresponsive.

I will do some more tests with a different laptop, preferably a windows machine. Try the logo and non-logo.

Thank you for the advise. I checked the download. On github the file is 117Kb when i download the file (i did this multiple times) it is always 119Kb. I tried with two different files. Same result.

Hi
I own a PanelDUE 7i and did a firmware update. I flashed file PanelDue-5.0i-7.0i-no-logo.bin with bossac tool. The file was downloaded from github Release 1.21.3. After the update. "touch the spot " is displayed I tried a few times but it is unresponsive. I'm stuck at this point.

I made a video of the process https://youtu.be/89sgUlBrJm8
