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.

[Marte Myrvold]

Hi,

Which getting started guide are you following? The guide on Infocenter for updating the firmware states that you should update the nRF52840 SoC with the Connectivity bridge firmware, see Updating Nordic Thingy:91 firmware for more information. This is also mentioned in the Working with Thingy:91 guide in our nRF Connect SDK documentation.

Best regards,

Marte
