nRF Desktop Programmer Tool always fails to flash nRF52840 dongle

Hi,

I can't program nRF52840 dongle using Programmer Tool on Linux.

Dongle is visible, can be selected and memory content read without any problems but file write attempt fails just after upload stage with message:
Failed with exit code 1. One or more program tasks failed: * EB0C69E9C501: requestSelect failed (Generic) Message: Failed, requestSelect failed.

Hi there,

So I have all three devices, both DK's and the dongle, "I can't program nRF52840 dongle using Programmer Tool on Linux."

I'm on windows 11, if I select the Dongle with the programmer it opens it in boot loader mode, If I open the BLE program and select it It prompts me to allow it to re-program it, YEs/Enter returns it to normal as the dongle, Note the name of the device changes so AFAIK it supports, (open boot loader , MCUBoot loader mode to use the programmer (if it's on the dongle) 

also It makes a difference if it is a real USB 3.0 or plain 2.0 

HTH

Hi ask6483,

Could you please enable verbose logging in the "About" tab of the app, and send us the full log from the failures?

So today the issue is gone, all programming attempts are successful, even when using USB hub. It doens't make any sense, I think that we can close this as this as this problem may only affect my system.
