Hello,
I am trying to do USB DFU on (NRF52840 with SDK 15.2) but when i run the nrfutil command it gives an error:
command: nrfutil dfu usb_serial -pkg ble_hrs_combo.zip -p /dev/ttyACM0 -b 115200
Output:
NordicSemiException: Unexpected Executed OP_CODE.
Expected: 0x02 Received: 0x41
I have uploaded the open bootloader hex file from examples/dfu/open_bootloader. and created the zip package using the following command:
nrfutil pkg generate --debug-mode --hw-version 52 --sd-req 0x008F --application ble_hrs_combo.hex ble_hrs_combo.zip
The ble_hrs_combo.hex was generated by merging the examples/ble_app_hrs and softdevice S140 (s140_nrf52_6.1.0).
What can be the problem?
