		60
		61	== 3.1 Use DAP-Link and Connect to the Device as above photos ==
		62
		63	We need to connect VDD，GND，SWCLK，SWDIO to DAP-Link.
		64
		65	* Connection method：
		66
		67	* GND-GND,
		68
		69	* VDD-3.3V,
		70
		71	* SWCLK-CLK,
		72
		73	* SWDIO-SWD

		83
		84	(((
		85	And then use PSoCProgrammer to upgrade the firmware (must use this version: PSoCProgrammer3.27.1)
		86	)))

		126
		127	== 4.1 Unable to detect upgrade ==
