Unable to program nrf52840dongle

Question

I have just received nRF52840 dongle and I cannot get it programed. I have tried both west flash and nrfProgrammer from nrfConnect. 
 I have been developing using nrf52840dk so far, and I have no issue programming the dk. In nrfProgrammer device comes as Unknown ( shown on attached nrf52840.png) I am attaching the log in a separate file nrfProgrammer.log Syslog output from Ubuntu 20.04: May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.303051] usb 1-2: new full-speed USB device number 15 using xhci_hcd May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453934] usb 1-2: New USB device found, idVendor=1915, idProduct=521f, bcdDevice= 1.00 May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453946] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453951] usb 1-2: Product: Open DFU Bootloader May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453955] usb 1-2: Manufacturer: Nordic Semiconductor May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453959] usb 1-2: SerialNumber: F3E11021BA23 May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.461463] cdc_acm 1-2:1.0: ttyACM0: USB ACM device May 23 09:32:33 jyu-ThinkPad-T470p mtp-probe: checking bus 1, device 15: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2" May 23 09:32:33 jyu-ThinkPad-T470p mtp-probe: bus: 1, device: 15 was not an MTP device May 23 09:32:33 jyu-ThinkPad-T470p snapd[1029]: hotplug.go:199: hotplug device add event ignored, enable experimental.hotplug May 23 09:32:33 jyu-ThinkPad-T470p mtp-probe: checking bus 1, device 15: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2" May 23 09:32:33 jyu-ThinkPad-T470p mtp-probe: bus: 1, device: 15 was not an MTP device west flash output: -- west flash: using runner nrfjprog FATAL ERROR: "nrfjprog --ids" did not find a board; is the board connected?

Do you have any suggestion on how can I program the dongle? Please let me know if you need any other information.

Hi, 
 Please try installing nrf-udev, https://github.com/NordicSemiconductor/nrf-udev . 
 Best regards,

Thanks for the reply. I was pressing the RESET button and the LED2 was flashing red indicating bootloader mode. Syslog on ubuntu was also indicating bootloader mode: May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453946] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 May 23 09:32:33 jyu-ThinkPad-T470p kernel: [ 4146.453951] usb 1-2: Product: Open DFU Bootloader In the and I have managed to program it for the "nRF Sniffer for Bluetooth LE" from Windows on the same PC(using exactly the same steps) in the end. Apparently there was an issue with the Ubuntu 20.04 environment for the nrf52840dongle ( although it works fine with the nrf528400dk) Now when booting without pressing RESET device is recognized as "nRF Sniffer for Bluetooth LE" . When booting with RESET pressed LED blinks red and device is recognized as "Product: Open DFU Bootloader" but still the nrfProgrammer is unable to program the device: 2022-05-20T10:38:48.210Z ERROR Error when fetching device versions: readFwInfo error 2022-05-20T10:40:42.521Z DEBUG Sending usage data... 2022-05-20T10:40:42.522Z DEBUG Category: pc-nrfconnect-programmer 2022-05-20T10:40:42.522Z DEBUG Action: Close device We need to be able to program the device from the Linux system. Any hints on resolving the programming issues on Ubuntu 20.04?
