      Hi,

       

      Do you mean download the firmware? You'll need a USB to I2C chip. With EZ-PD Configuration Utility, you'll be able to download the .cyacd firmware file. You can refer to the mother board of CY4532:

          Sorry, that is not what I am looking for.  I have a HW board that has an I2C interface to the parts.  I have custom code on the parts.  I want to be able to load new hex files into the parts from a general purpose processor over the I2C interface to the cypress part.  the GPP is the master and the cypress parts are the slaves.  I am looking for SW examples for both the GPP and the cypress parts on how to program the devices over the I2C interface.  Parts I am using include CYPD-4225-40LQ and CYPD-4226-40LQX.

            Hi,

             

            In order to do that you'll need the HPI spec for CCG4. However, these files can only be discovered under NDA currently. You need to contact Cypress local sales.
