nRF Connect v3.2.0 issue for nFR9160

 Hi, 

I am new to Nordic Thingy91.


I have tried to connect Nordic Thingy91 (nRF9160) device using "nRF connect v3.2.0", via USB.
But I am facing, below issue.

Issue 1: "unsupported device: the detected device could not be recognized as neither jlink device nor nordic USB device for windows 10"

Tried: I have tried installing different versions of J-Link from below:
www.segger.com/.../
(Tried with: 6.22g,e 6.50e, etc.,)

But no luck, and below issue is seen,

Issue 2: "unsupported device with serial number PCA_20035_d081421f4d65 and trails ["serialport"]"

Is JTAG necessary to flash/program the "nRF9160" and "nRF52840"..?

Host Machine Details (Where I am trying to flash/Program the nRF9160):
Windows 10
nRF Connect v3.2.0

NOTE: Apart from nRF Connect v3.2.0, I didn't installed any tools in windows 10 machine.
I have a Nordic Thingy91 development environment (including SEGGER) in a different machine. Planing to use windows 10 to flash/program the nRF9160 remotely.


I was able to successfully compile and generate the binary (Ex: Asset tracking) in the development environment.

Please direct me to the correct path, whether I am missing anything on Windows 10 machine to flash/program the nRF9160.


Thank you for your help.

    I am ready to burn the nRF52840 (PCA20035) with app_update.bin/merged.hex on thingy91 device using "mcumgr"

     As I have said, due to driver issues on Windows 10, I do not believe you will be successful. However, you can try to power on the Thingy:91 (while connected to your computer of course) while holding SW4 (the tiny white button). If it appears in the Windows Device Manager as "MCUBOOT" with a small orange triangle on (see picture), you will not be able to update the firmware using MCUBoot/mcumgr.

    is there any possible way that I can bring back nRF52840, if MCUBoot flash fails with "mcumgr"

     If the flashing with mcumgr fails, you have probably not done anything to the firmware on the 52840, so there is nothing to worry about. If you flash firmware to the 52840 (or the 9160) without MCUBoot, you will not be able to revert without an external programmer. If you have an nRF52 DK, you can use it to recover the 52840 on the Thingy:91, but it not work on the nRF9160.
