Hello chenglei wang,
Please use 'noboot.cydsn' project in the same project folder as the 'noboot.cydsn' is a debug-enabled version of the same firmware application, which does not depend on the bootloader. Please use PSoC Creator 3.3 for the projects to build efficiently.
Please refer CCGx_FW_UserGuide in the installation folder of the CCGx SDK for more information and the same is attached for reference.
