Hi,

I am trying to customize FW behavior for CYPD2103-14LHXI for e-marked smart cable, to have control of I2C and GPIO(LED) pins. However, in the CCG2 SDK 3.0.2 I only find examples for power adapter, notebook and mobile applications, not EMCA. After removing the bootloader and some pins, I was able to build and program the power adapter example for CYPD2103-14LHXI and the LED is blinking, however it looks like the FW is stuck in IntDefaultHandler(), and does not respond to any communication on the CC line.

So, my questions are:

  1. Where is the SDK example for the CCG2 EMCA reference design?
  2. Is it possible to program CYPD2103-14LHXI to act as DFP?

Thanks

Hi Carl,

  1. Where is the SDK example for the CCG2 EMCA reference design?

>> CCG2 EMCA firmware SDK example is not going to release out. If you need any customize, feel free to contact local Cypress FAE to get support. Contact information: Cypress Franchised Distributors

     2. Is it possible to program CYPD2103-14LHXI to act as DFP?

>> No. Since CYPD2103 is target for Cable. The terminate resistor is Ra. If you are going to design DFP, the terminate resistor is Rp.

Best Regards,

Lisa
