Hi,

I see you have selected thingy91_nrf52840 as build target. This build target is the nRF52840 SoC on the Thingy:91, and not the nRF9160 SiP. The Asset Tracker application is made for nRF9160 and is not supported on other chips. Please use thingy91_nrf9160ns as build target when programming the Asset Tracker application for the Thingy:91. For more information about supported boards, please see Asset Tracker requirements.

Best regards,

Marte

[machinehum]

Thanks for the reply, what if I want to build the firmware for the nrf52 IC on the thingy91?

This is described here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thingy91.html under the "Building and programming on the command line" section.

Here is my most recent build spew, it's trying to link against a FPU lib that doesn't seem to exist.

[Marte Myrvold]

Hi,

If you want to build firmware for the nRF52840 SoC on Thingy:91 you should still use thingy91_nrf52840 as build target. However, the Asset Tracker application is a nRF9160 application, and is only supported on the nRF9160. You will not be able to use this application on a nRF52 SoC. Thus, you cannot build and program this application to the nRF52840 SoC on Thingy:91. You will need an application or a sample that is supported on nRF52 SoCs.

The only sample in NCS that is officially supported on thingy91_nrf52840 is the Connectivity bridge, and is therefore the only sample we can guarantee works. You can try to program other samples to the nRF52840 SoC on Thingy:91, as long as they are supported on nRF52. However, we cannot guarantee that these samples will work out of the box.

Best regards,

Marte

[machinehum]

Thanks for the reply, all I'm trying to do is build/flash the latest firmware on the nRF52 situated on the PCB of the Thingy91. If I reading this properly the firmware the located in the ncs/nrf/applications/connectivity_bridge folder.

Thanks for this info, the getting started guide doesn't allude to this at all.
