Complete echo_bot build/flash/reset/UART workflow (user-provided commands):

# 1. Build
cd ~/ncs/v3.0.2 && nrfutil toolchain-manager launch --ncs-version v3.0.2 -- west build --build-dir /home/paul/Documents/echo_bot/build /home/paul/Documents/echo_bot --board Scout/nrf5340/cpuapp -- -DBOARD_ROOT="/home/paul/Documents/custom_boards_nrf"

# 2. Flash
cd ~/ncs/v3.0.2 && nrfutil toolchain-manager launch --ncs-version v3.0.2 -- west flash --build-dir /home/paul/Documents/echo_bot/build

# 3. Reset device
nrfutil device reset --serial-number <SERIAL_NUMBER>

# 4. UART capture (30s timeout)
We use Uart for logging!
timeout 30 minicom --device /dev/serial/by-id/<id> --baudrate 115200

Notes:
- Use nrfutil toolchain-manager launch wrapper for NCS v3.0.2
- Board: Scout/nrf5340/cpuapp with custom BOARD_ROOT
- Serial number for reset: <SERIAL_NUMBER>
- UART device: /dev/serial/by-id/<id>
- Timeout 30s on minicom to auto-exit
- Start the UART and directly after that reset, to get the output
