Thanks for your help,

The following set of command works for me

$ cd ~/src/ot-nrf528xx
$ rm -rf build
$ script/build nrf52840 USB_trans -DOT_BOOTLOADER=USB -DOT_JOINER=ON -DOT_COMMISSIONER=ON
$ cd ~/src/ot-nrf528xx/build/bin
$ arm-none-eabi-objcopy -O ihex ot-cli-ftd ot-cli-ftd.hex

Hi,

Please use the Thread samples in nRF Connect SDK instead. You can find the documentation for the samples here: nRF Connect SDK - Thread samples.

The write button is disabled because the firmware you are trying to upload to the dongle overlaps with the MBR (Master Boot Record) on the dongle. You can see this by hovering over the regions in the Programmer app. The MBR occupies 0 - 0xFFF, so applications must start at 0x1000. This is handled automatically in nRF Connect SDK when you build for the nRF52840 Dongle.

Best regards,
Marte
