Thank you for taking the time to post your solution here.

I got it working. =)

here my instructions:

# Install nrfutil on RPi4

```console
mkdir nrfutil
cd nrfutil
curl -LO https://github.com/NordicSemiconductor/pc-nrfutil/archive/v6.1.7.zip
unzip v6.1.7.zip
cd pc-nrfutil-6.1.7
```

replace "pc_ble_driver_py >= 0.16.4" to "pc_ble_driver_py" in requirements.txt
```console
sed -i 's/pc_ble_driver_py >= [^ ]*/pc_ble_driver_py/' requirements.txt
```

check max python version in setup.py with the python on the system
python_requires='>=3.7, <3.11',

```console
python3 -m pip install -r requirements.txt
```

if `python3 -m pip install -r requirements.txt` not working? check [[https://stackoverflow.com/questions/75602063/pip-install-r-requirements-txt-is-failing-this-environment-is-externally-mana](https://stackoverflow.com/questions/75602063/pip-install-r-requirements-txt-is-failing-this-environment-is-externally-mana)]

may try:
```console
python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install -r requirements.txt
```

```console
pip install .
```


perform dfu via serial (the start may takes some time up to 30 seconds or more):

```console
nrfutil dfu serial -pkg app_dfu_package.zip -p /dev/ttyAMA0 -b 115200 -prn 1 -fc 0
```
or
```console
nrfutil dfu serial -pkg app_dfu_package.zip -p /dev/ttyS0 -b 115200 -prn 1 -fc 0
```
`/dev/ttyAMA0` for (Bullseye) and `/dev/ttyS0` for (Bookworm)?

perform dfu serial with debug
```console
nrfutil -v -v -v -v dfu serial -pkg app_dfu_package.zip -p /dev/ttyAMA0 -b 115200 -prn 1 -fc 0
```

Getting serial DFU to work on the Pi should be possible without much effort as it doesn’t rely on precompiled C libraries like DFU over BLE. What version of Python is installed on this Pi? You might need to use an older version than the one distributed with the OS, but it should be Python 3, not Python 2. Python 3 is compatible with version 6.1.7.

Does this work really on Raspberry Pi ? I mean its ARM. I see nowhere that this is supported.

For me this:

sudo nrfutil -v -v -v -v dfu serial -pkg app_dfu_package.zip -p /dev/ttyAMA0 -b 115200 -prn 1 -fc 0

is not working on Raspberry Pi (using nrfutil version 5.2.0). On Windows (nrfutil version 6.1.7) no problem.
Bootloader has disabled HWFC and Baudrate is set to 115200.

Thanks for updating the thread. You may also consider giving your user write access to ttyACM0 so you don't have to run the script as root.

Adding sudo to the command did the trick.

sudo nrfutil -v -v -v -v dfu serial -pkg ot-rcp.zip -p /dev/ttyACM0

works fine
