KBA97271 is a obsolete KBA, and we are going to remove it from our website.
You can use CY4532 to program chip over CC line with EZ-PD Configuration Utility.
Thank you for the clarification.
I'd like to add some additional related information I've learned.
To switch from the I2C bootloader to the CC bootloader, reference the following post with details: https://community.cypress.com/message/195209#195209
Looks like the trickiest bit is making cure the CC bootloader FITS. Note, if using the CCG2, it is fairly flash space constrained and the CC bootloader takes up more flash than the I2C bootloader.
FYI: In the above post, LIsaZ points out "CCG2 CC bootloader is supported by CY4501 or CY4531. CY4521 is not supported."
Also reference post Support CCG5 firmware update over CC-lines? which is a testament to the ability to create the code, though the final code or process to create the code isn't shared here.
