USB EZ-PD™ Type-C

我使用型号是：CYUSB3013，现在通过GPIO53~56作为串口，使用官方的例程，不能输出信息。官方工程连接：https://www.cypress.com/documentation/application-notes/an75779-how-implement-image-sensor-interface-using-ez-usb-fx3-usb

Hi, Sir,

I have a intel Alder-Lake platform project, and customer is design schematic using CCG5C.  

Dose Host SDK - CYPD5126-40LQXI_notebook_tbt project can support Alder-Lake?

To confirm that the bootloader is running, I'm toggling 2 GPIO pins to indicate that I've entered main() in the bootloader.  If I build the bootloader project and load the hex file into the CCG3 I see the pins toggle when the device is powered on.  If I specify this bootloader in the bootloadable component in my main project I don't see these pins toggle when the device powers on.  Am I missing something on how this firmware runs?

Hi,

I am using CCG3PA board in my device to work  as PD source and QC source.

It was working as PD source fine but it is not working as QC source when i connect it to QC sink.

How can i switch ccg3pa from PD to QC mode?

All QC related flags are set in my code BATTERY_CHARGING_ENABLE and below  provided with my EZ-PD configuration utility screenshot. 

When i connected a sniffer between My device and sink it is sending Source capabilities for some time and then vbus is droping to zero when there is no response from sink.

Is there any Flags i am missing to enable ? can you suggest procedure to switch between PD source mode to QC source mode?

Thankyou.

Hello,

We have implemented a CYPD3125 on our latest ultrasound scanner.  We use the firmware of the evaluation kit with some modifications to the configuration table.  We have one source PDO (5V / 1.5A) and two sink PDO (5V / 900 mA and 15V / 3A).  Our system required 15V / 3A to work.

When we connect a USB-C power adapter our system request 15V / 3A and it starts working properly.  But sometime  after few seconds or few minutes the CYPD3125 turn off the consumer path and our system stop working.  When we measure the VBUS the 15 volts is still there but the gate of the two transistors that control the consumer path are at 0 volt.

What can cause the CYPD3125 to turn off the consumer path?

Thank you

Best Regards,

Patrice

We use Host SDK to implement TGL platform  

Currently we have one fail item in eye diagram.

How to adjust BB-RETIMER ( ex : EQ ) to improve eye diagram?

When i enable OTP function by EZ-PD configuration utility ,

There have two parameters, one is "cut off" , another is "Restart value"

How to set those parameters? What is the unit?

The FW use "pd_hal_measure_internal_temp" function to get internal temperature.

The function return value unit is ℃, right ? ex: if chip internal temperature is 100℃ , the function will return 100, right?
