What document discusses which I2C the boot loader is accessible thru and what address you need to communicate with to update the firmware. I see lots of documents that discuss it can be done, but none specifically telling you which I2C to connect with and how to address it.
My application is connecting an MCU directly to the I2C port of CYPD2122-24LQXI. I'm not using a serial bridge or MIniprog.
Programming CCGx with I2C through I2C bootloader follows Cypress HPI spec.
You can get the spec under NDA. Please contact the local FAE to get the NDA signed.
