Prepare the Hardware
a) Power Supply
You may use either J1 or J4 to provide power to the Halley2 development kit.
1) POWER_DC 5V Input (J1). Power switch (K1) is used to enable/disable the power.
2) USB_DOWNLOAD Port (J4). Except power supply, this port can also be used to program the Flash.
b) Debug Port: USB_DEBUG (J12)
J12 is the USB to serial debug port.
Boot Halley2 Normally
First use two USB cables to connect the USB DOWNLOAD (J4) and USB DEBUG (J12) ports with your PC.
Then press the RESET key (SW4) to boot the Halley2.
Configure the parameters of the USB serial port to 57600bps-8N1.
Boot Halley2 to the USB BOOT MODE (Flashing the Halley2)
Press and release the RESET key (SW4) while keeping pressing download the BOOT key (SW3), then Halley2 will boot to the USB BOOT MODE.
You may use the USB cloner tool to flash the SPI flash under the USB BOOT MODE.
