Thingy91 unresponsive after building and downloading Asset Tracker

[gerardmason]

I have previously built the Asset Tracker downloaded it to my 9160DK with no problems.

Today I connected my Thingy91 and updated it's firmware. Afterwards I built the Asset Tracker and downloaded it, but the board is unresponsive now. No LEDs come on, nothing shows in the LTE Monitor, the board just seems dead. I have downloaded a Hex file for the AT Client example and it's working fine (no LEDS though, but responsive to AT commands in LTE Link Monitor).

Is there anything I should be trying? I'm not sure how to move forward now.

Hi,

Today I connected my Thingy91 and updated it's firmware. Afterwards I built the Asset Tracker and downloaded it, but the board is unresponsive now. No LEDs come on, nothing shows in the LTE Monitor, the board just seems dead. I have downloaded a Hex file for the AT Client example and it's working fine (no LEDS though, but responsive to AT commands in LTE Link Monitor).

The at_client shouldn't light up any LEDs, so that seems to be working correctly.

The asset_tracker should light up LEDs, and also print out debug messages. Are you certain that you have updated the "nrf" repo correctly? This can be done by issuing:

cd path/to/ncs/nrf

west update 

Also, remember to choose the correct board, which is nrf9160_pca20035ns for the thingy running asset_tracker application.

 

Kind regards,

Håkon

Ok I see - I had forgotten to choose a new board after testing on the 9160DK.

I've updated nrf and run west update. I don't see a nrf9160_pca20035 folder in /ncs/zephyr/boards/arm, but I see one in /ncs/nrf/boards/arm. I've tried this, but I now get an 'Out of tree board' error.

Ah! I found the issue.

I went back to the Getting Started Assistant app and read through the steps. One of them is: 

git checkout <ncs_tag>

I noticed when I did this that git reported that I was in a detached head state. To fix this I ran:

git checkout -b v1.0.0

...needed to add the -b to create a local branch from the remote branch.

Now I can select the correct board, and it builds fine. Downloaded to the Thingy91 with success!

Thanks,

Gerard

Hi,

 

Good to hear that you got it working. Note that features like GPS were added after the v1.0.0 tag, so if you want that, you have to check out the master branch.

 

Kind regards,

Håkon
