These devices are listed using the mcuboot
trait.
Build your nRF Connect SDK project for the nRF9160 System in Package (SiP)
of the Nordic Thingy:91™, for
example, the thingy91_nrf9160_ns and use the file
build/zephyr/app_signed.hex generated, see Multi-image builds
- Find the device serial number by running the following:
nrfutil device list --traits mcuboot
-
Before programming, put the nRF9160 SiP of the Nordic Thingy:91 in
application serial recovery mode by holding in the SW3 button
while powering it off and on.
-
Program build/zephyr/app_signed.hex to a device with serial number THINGY91_xxxxxxxxxxxx, by running the following:
nrfutil device program --firmware build/zephyr/app_signed.hex --serial-number THINGY91_xxxxxxxxxxxx
If
nrfutil device fails with a timeout error during step 3,
put it into application serial recovery mode as described in step 2. See also
Troubleshooting.
