nrfjprog no detect devices - OSX - nrf91 Thingy

[Vincent MORENO]

Hello,

I'm quite loss using the command nrfjprog.

I install in VSCode all NRF tools. It seems working good. I can compile.

When I have a look on "device tree" I cannot see any devices. So I try nrfjprog -i  --log and I have this message:

/Applications/Nordic Semiconductor/bin>nrfjprog -i --log

WARNING: Logging is unavailable. nrfjprog.exe does not have write

WARNING: permission for the log file

It is strange beacause the program is talking about exe file and I'm under MAC OSX.

I'm sure the device is connected:

/Applications/Nordic Semiconductor/bin>ls /dev/tty.usbmodem1410*

/dev/tty.usbmodem14101 /dev/tty.usbmodem14104

The version is 

/Applications/Nordic Semiconductor/bin>nrfjprog --version

nrfjprog version: 10.15.0 external

JLinkARM.dll version: 7.56a

Thanks for your help

Hi Vincent,

Different from nRF9160DK, Thingy91 does not have an onboard Jlink debugger.

You have to connect an external debugger or update FW with MCUBOOT through USB.

nrfjprog only works with SEGGER J-Link programmers and debuggers.

Best regards,

Charlie
