Build asset tracker for Thingy:91

[XavierN]

Hello, I am trying to build the asset tracker reference app for my newly acquired Thingy:91.

I went through the instructions to get the toolchain and SEGGER IDE up and running

Then I Select "open nrf connect SDK project" and select:

CMakeLists.txt: $BASEDIR/ncs/nrf/applications/asset_tracker/CMakeLists.txt

Board Directory: $BASEDIR/ncs/nrf/boards/arm/nrf9160_pca20035

But I am getting the error:

`kconfiglib.KconfigError: $BASEDIR/ncs/nrf/boards/arm/nrf9160_pca20035/Kconfig.defconfig:53: couldn't parse 'default $(dt_chosen_reg_size_hex,$(DT_CHOSEN_Z_CODE_PARTITION))': macro expanded to blank string`

I see that this config parameter DT_CHOSEN_Z_CODE_PARTITION is not present in the nrf9160DK Kcondif.defconfig file but I don't know how to configure it or to which value.

Also, I see that the Thingy:91 board dir is out of tree, any chances that it will be added soon?

Thank you.

Hello Xavier, 

What instructions did you follow? 

In SES, have you configured the Zephyr base address? (Tools -> Options -> nRF Connect)

Did you run "west update" after "west init"?

cd <sourcecode_root>
mkdir ncs
cd ncs
west init -m https://github.com/NordicPlayground/fw-nrfconnect-nrf
west update


Kind regards,

Øyvind

Hello,

I followed the instructions in the "Getting Started Assistant" from the nrf Connect SDK app.

I actually found the problem, when filling in the form after "File -> open nrf Connect SDK Project" i should have chosen "nrf9160_pca20035ns", it defaults to the one without the "ns" and that was wrong.

So my next question now that I can build it is: I only have the Thingy:91, I don't have the nrf9160 DK board, I found the instructions on how to install my merged.hex file using the Thingy:91 connected to the USB port. But is it possible to debug the application? At least to get the "printk" statements somewhere?

Thank you.

Yes of course, we would be interested in using multiple positioning systems, not only GPS, in particular Galileo and Glonass. For what we gather in the Thingy 91 specs only GPS is supported at the moment.

So my question would be if there are any plans to making the Thingy91 or its evolution capable of using multiple global positioning systems? I guess one always could build its own device based on the nRF9160 system and then add a GNSS compatible peripheral?

I have forwarded your question to the nRF91 team regarding GNSS.

Yes, this is a valid solution.

Appreciate it, thank you.

Hello again, 

I'm sorry, there is currently no support or plans of support for GNSS. Your suggestion is currently the best solution.

Kind regards,
Øyvind

Ok thank you for taking the time to look into it.
