CY8C24894-24LTXIT is an empty device, so it doesn't have a i2c address.
This device supports BootldrI2C user module which can be used to realize an I2C bootloader function, if you create a bootloader project use BootlarI2C module and program in the device, then you can upgrade firmware into device through I2C interface.
Thank you. I will look further into it.
Cypress provide Host software for I2C bootloader, you can find it in
