Flashing the Arduino 101 board over DFU can be tricky: the dfu-util command line is cumbersome, and the reset button must be pressed at the right time. This script brings the convenience of 'make flash' for the Arduino 101 board and for other boards that support the DFU protocol. It checks whether the board is in DFU mode, and prompts the user to reset it when needed. The dfu-util command line is constructed from the following environment variables, to be exported from the Makefile: - DFUUTIL: path to the dfu-util executable, default: dfu-util - DFUUTIL_PID: vendor_ID:product_ID of the board in DFU mode - DFUUTIL_ALT: alternate setting name of the DFU interface - DFUUTIL_IMG: path to the binary image sent to the board Change-Id: Ia9577ec96102a92d4c60481f980f30f4f6e7cd9e Signed-off-by: Patrice Buriez <patrice.buriez@intel.com>
