Flashing from rPi or KUbuntu 24.04 won't work

Official Hardware UNO Family UNO Q

The flashing does fail once the software in downloaded and extracted with

qdl: unable to open device

I see no issue with qcserial but I removed that module and I also stopped ModemManager and still “qdl: unable to open device” and this is using flasher v0.3.0 for Linux on both ARM and AMD64 architectures.

They are using a Qualcomm tool called qdl to do the flashing and you can find it in /tmp/qdl-xxxxxx directory during the running of arduino-flasher-cli but because they generate a new temp directory for the download of the qdl tool I can’t link in a debugging version to see what’s going on.

If anyone has any ideas let me know because this bug is 3 weeks old so nobody running Linux can flash the updated image to the Uno-Q.

I am running Ubuntu 24.04 and have updated without problems. That said.. apps lab was not able to run before without applying the change in https://forum.arduino.cc/t/solution-arduino-app-lab-ubuntu-does-nothing-when-selecting-the-board/

maybe that helps

@paulvha, you ran “arduino-flasher-cli flash latest” and it worked?

I have no problem running Arduino App Lab over USB or Network.

It was the flashing of the OS image which fails for me on both an rPi and my Kubuntu 24.04 laptop. I was able to get it to flash by powering off the Uno-Q, unloading the qcserial module( sudo rmmod qcserial ), powering up the Uno-Q and then running “sudo ./arduiono-flasher-cli flash latest” but WHY do we need to run the tool as super-user???

And hey, the Linux section of the flashing page tells us to download the Darwin ARM64 version!
