Arduino Nano 33 BLE: flash program through USBhttps://devzone.nordicsemi.com/f/nordic-q-a/60710/arduino-nano-33-ble-flash-program-through-usbHello everybody, I&#39;m trying to flash an example code (let&#39;s say the blinky one) from the SDK (15.3) onto the Arduino Nano 33 BLE board. I know that is possible to flash FW using a JLink or a NRF DK. The point is that using Arduino IDE, it is possbileen-USTelligent Community 13Mon, 27 Apr 2020 11:35:16 GMTRE: Arduino Nano 33 BLE: flash program through USBhttps://devzone.nordicsemi.com/thread/246790?ContentTypeID=1Mon, 27 Apr 2020 11:35:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8b4baccb-01cb-4dab-aa41-5ad61e893927J&#248;rgen Holmefjord<p>Hi,</p> <p>The board probably comes flashed with the Arduino bootloader. This is not supported by our nRF5 SDK, but we provide our own <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/sdk_app_serial_dfu_bootloader.html">serial bootloader with USB transport</a>. If you flash the board with the USB bootloader using a J-Link/nRF5 DK first, you can perform DFU (application updated) using <a href="https://infocenter.nordicsemi.com/topic/ug_nrfutil/UG/nrfutil/nrfutil_intro.html">nrfutil</a> command-line tool.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
