It seems like that to me too! I just wasn't expecting to need to do that out of the box, as it is sold as a standalone dev platform. Will report back when my programming cable/adapter arrive later this week.

Hello Tim,

Did you follow the official guide in our Infocenter:?

To me it sounds like you need to update the nRF52840, from repository at https://github.com/nrfconnect/sdk-nrf Full commit SHA: 8e8c60897eac40f61db9f578ce521970fff8e4d2 Package contents: img_app_bl/ Full application images, including img_fota_dfu_hex/ Application only.

In order to use the 10pin JTAG cable you need to have a JLink programmer that supports Arm Cortex M33, or the nRF9160DK. However, you should be able to program the Thingy:91 using MCUboot.

Let me know how it works.

Kind regards,
Øyvind

Tried putting it into Serial mode - per https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/thingy91_2d00_fw_2d00_update_2d00_mcuboot?tempkey=af326acc-b25a-46b3-8c0b-a70826e0878f - but no dice, I am not seeing any USB serial connections showing up in System Info.

I've gone ahead and ordered the 10pin JTAG (smaller pitch) cable and adapter, but a bit disappointed that it's this involved out of the box.
