In our own hardware design (with usb-c connector) the FX3/CX3/FX3S comes up as "Cypress Benicia USB Boot Device" instead of "Cypress FX3 Bootloader Device" and we were able to program successfuly the cycx3_uvc_ov5640.img firmware (accordig to Control Center: "Programming of I2C EEPROM Succeeded") via I2C EEPROM. But the device always comes up with Cypress Benicia USB Boot Device.

We have just checked the PMODE[2:0] states and:

Trouble Shooting Guide for the FX3/FX3S/CX3 Enumeration - KBA222372

and:

It is seems that it is a hardware issue because in FX3 DVK everything goes OK.

Any other help?

Thank you very much in advance!

Hi Raul,

I see that C5 pin (RESET#) is left open. 1ms (minimum) POR is needed to provided to this pin.

Please test it providing the same and let me know the result.

Regards,

Hemanth
