Hello
I have just received thingy:91 x to start learning nrf platform. Unfortunately it's not all smooth. I am trying to do flash Blank application. It builds fine but then when I try to flash thingy I get error (see below).
Maybe I missed something important, but I did follow all the docs
$ nrfutil device program --firmware build/dfu_application.zip --serial-number THINGY91X_46EEE9... --traits mcuBoot --x-family nrf91 --core Application
