I also have 2x brand new nrf9160 feathers. I have tried to power these up via the usb-c from computer, as well as the battery port with 3.6V. However, there is no LEDs lighting up when trying to power it up.
I have tried to measure the voltage on the board, and it seems to be fine with the battery port (not measured with usbc).
I have also tried to look at connected usb devices on my computer when connected through usbc, but nothing shows up.
Does anyone know what the issue might be?
Can you confirm the cable you’re using works on other devices? Are you plugging the nRF9160 Feather into anything else? Did you solder headers on?
Hey!
It was the cable, thanks!
jaredwolff Do you by any chance know what this error might be related to:
nrfjprog version: 10.23.2 external
JLinkARM.dll version: 7.88j
computer: mac
When I run the: nrfjprog -r on the nrf9160 DK I get:
Applying system reset.
Run.
However, when connecting the feather with a TC2030-CTX-NL 6-Pin I get this error:
[error] [ Client] - Encountered error -102: Command connect_to_emu_with_snr executed for 576 milliseconds with result -102

Depending on your development board, you may need to solder a jumper to force usage of the external connector rather than the on-board chip. Also the nRF9160 can only be programmed by the nRF91DK, nRF53DK, or anything else newer.
jaredwolff I have it connected with the usb-c. However, there is no constant green LED light on the feather. It lights up for 1 sec when plugging in the usb-c, then turns off.
I am able to get the blue LED lighting up constantly by holding the MODE down when plugging in the cable.
Yes I am using the nrf9160 DK
Thanks!
therustyalex However, there is no constant green LED light on the feather. It lights up for 1 sec when plugging in the usb-c, then turns off.
The green LED is for the battery chragee. W
It will only turn on if you have USB and a low battery connected (when it’s charging)
therustyalex I am able to get the blue LED lighting up constantly by holding the MODE down when plugging in the cable.
This is only important for the bootloader. If you’re programming using the Tag Connect the LED state won’t matter.
Can you explain what you’re trying to accomplish by using the Tag Connect?
jaredwolff Thanks!
So I am successfully flashing my rust code to the nrf9160 DK. My ambition is to do the same on the feather through the DK
So if I understood LEDs correct, there should be no LEDs lighting up when only the usb-c is connected and not in the bootloader?
therustyalex So if I understood LEDs correct, there should be no LEDs lighting up when only the usb-c is connected and not in the bootloader?
If you don’t have code on there that isn’t toggling/using the LED, then yes it shouldn’t light up. You should be able to program using the Tag Connect irrespective of the LED state.
jaredwolff I see.
So I tried checking the nrf connect desktop programmer tool, and I got this:
Does this make any sense to you?

I install the CLI tools and invoke nrfjprog from the CLI. That’s what the Zephyr Tools: Flash command uses under the hood.
I suggest you reviewthe documentation carefully around this subject:
jaredwolff Thanks.
So I followed the tutorial closely and opened a terminal and run nrfjprog -r.
When not having the feather connected via the Tag Connect, the command successfully runs, but still getting the error when hooking the feather up:
[error] [ Client] - Encountered error -102: Command connect_to_emu_with_snr executed for 881 milliseconds with result -102
ERROR: Unable to connect to a debugger.
[error] [ Worker] - An unknown error.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
I have not jumped the SB47 on nrf9160 DK. However, as the error only occurs when hooking up the feather on the Tag Connect, it may indicate that the DK know an external devices is connected?
Also spoke with nordic regarding this issue, their answer:
Is the voltage level of nRF9160DK and the feather same? This should be same.
Both the DK and the feather are connected to my mac through a Satechi adapter. Which seems to power the DK and feather.
If your DK is not jumped it may not work well. Can you share a picture of your setup?
Sure!
I sometimes have to hold the Tag Connect with a bit of pressure on the feather to make sure it is connected.
Cool thanks. Make sure you really squish it down. A light touch doesn’t work well.
Also do you have the latest JLink? You should download the latest to make sure your DK is up to date. (Running jlinkexe should prompt you to update your DK firmware if it’s out of date)
I would also, if you can, make sure your external connector doesn’t have issues by programming another board. (Or simply issuing a nrfjprog -r)
Yeah I squish it down firmly.
I have tried using the latest JLink, but the latest version of nrfjprog command seem to want JLinkARM.dll version: 7.88j
Which I get from this download: https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download#infotabs
So regarding keeping my DK up to date, this is my log:

10 pin connector is changed on the newer version of DK.

Do you think your external board as same connection as this https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/ext_programming_support.html?cp=2_0_4_3_11_0?
