// ----------------------------------------------------------------------------
// Flashing
//
// Special version of bossac is required.
// This executable can be obtained two ways:
//  1. In Arduino IDE, install support for the board ("Arduino Mbed OS Nano Boards")
//     Search for "tools/bossac/1.9.1-arduino2/bossac" in Arduino IDEs directory
//  2. Download https://downloads.arduino.cc/packages/package_index.json
//     Search for "bossac-1.9.1-arduino2" in that file
//     Download tarball for your OS and unpack it
//
// Once you have the executable, make it accessible in your PATH as "bossac_arduino2".
//
// It is possible to replace original bossac with this new one (this only adds support for nrf chip).
// In that case make "bossac_arduino2" symlink on it, for the board target to be able to find it.
//
// ----------------------------------------------------------------------------
// Bluetooth
//
// SoftDevice (s140v7) must be flashed first to enable use of bluetooth on this board.
// See https://github.com/tinygo-org/bluetooth
//
// SoftDevice overwrites original bootloader and flashing method described above is not avalable anymore.
// Instead, please use debug probe and flash your code with "nano-33-ble-s140v7" target.
