Hello William,

CYPD2134 project has CC boot loader, you can copy the cc bootloader to your project, change the part number in the CC bootloader project and build it to generate the .elf and .hex files. Include these in the bootloadable dependencies of your project.

Please refer to this thread.

Best Regards,

Sorry, it is my typo, I want to change CY4541 I2C bootloader to CC bootloader, not CY4521.

Hello William,

For CCG4 CC boot loader designing, you can refer to the CCGx power SDK which contains CC boot loader for CCG3PA under firmware->projects.
