Error when deploying to nrf52840_dongle

[RubensZimbres]

I will use Nordic nrf52840 dongle for 2FA + security key on Google login. I successfully run setup.sh, installed rustup, tockloader (via github) but when i run:

./deploy.py os --board=nrf52840_dk

I get the following error:

   Finished release [optimized + debuginfo] target(s) in 0.25s

[STATUS] Flashing binaries to board
[ INFO ] Using known arch and jtag-device for known board nrf52dk
[ERROR ] ERROR: Cannot find JLink hardware. Is USB attached ?
make: *** [flash] Error 1
fatal: Failed to execute make: Command '['make', '-C', 'third_party/tock/boards/nordic/nrf52840_dongle', 'flash']' returned non-zero exit status 2.

I tried to update the dongle driver with JLink driver but it's not working. Windows recognizes it and it is currently on port COM3

When I open JLink.exe, it tries to connect via USD but a pop up opens; "No emulators connected via USB" and it wants to connect via TCP/IP.

What are the possible solutions to this issue ? Nordic nrf52840_dongle is connected to USB port.

Hi, do you have a Segger J-Link connect to your computer?

You could check detailed installation guide, some hardware debugging tools shows in the prerequisite.

If you want to deploy OpenSK without debugging tools, you should check this thread #3
