hi 我需要修改CYPD5225-96BZXI_notebook_tbt案例工程来 配合Goshen Ridge IC,由于我们的hardware设计不同 ,需要把案例中的RTM I2C和 RETIMER_PWR_EN_P1、RETIMER_FORCE_PWR_EN.......等如图中的去掉,去掉之后又将config.h中的相应的enable也置0,并把RETIMER_FORCE_PWR_EN.c和RTM.c等相关文件remove,之后build还是fail error如下图,我Find了RETIMER_FORCE_PWR_READ这个函数这个workspace也没有,请问是哪里还没有删减干净吗?为什么会出现这个error?

We use CYPD6227 (CCG6DF) two port PD controller ( Port 0 and Port 1 ) to implement alder lake platform.
but actually our project is single type-c port design.
I have some question ?
1. The Host SDK 3.5 project has two INT pins , one is AR_INT_P1 (P0.4) , another is AR_INT_P2 (P0.5)
Does it mean CCG6DF use two interrupt pin to communicate ( notify event ) with alder lake PCH ,
one is for port0, another is for port1 ?
2. Because our project is single port application, how to disable Port 1 ? will it affect communication with PCH when disabling Port1?
3. How to remove BB_RETIMER controlled? because HW doesn't have BB_RETIMER.
Show LessHello,
I have multiple DMC chips in my system with the same VID/PID connected to the same computer, each with its own unique serial number. Unfortunately, the current version of ezpd_dockupdatefw.exe, when run with VID/PID command line parameters, fails if it detects more than one such device. It would be great to add another "serial number" command line parameter to the ezpd_dockupdatefw.exe tool so that it can only program the device selected by that number.
Another very useful option would be to add the -all parameter to this tool to program all devices that match the VID/PID criteria.
Thanks,

1. Does Host SDK support Intel Maple Ridge platform?
if supported, which SDK's project is used for Maple ridge ?
3. another question , what difference between CYPD6227-96BZXI and CYPD6228-96BZXI?
CCG6DF - datasheet note 8 - Optimized ROM code, what is meaning ?
Show LessDear all,
Can you send me the driver of CY4500, to
Liam.liu@corp.ovt.com
I also cannot found the driver folder after installed the EZ-PD Protocol analyzer version 3.1.0.
I am using Windows 10 64-bit OS.
Thank you.
Show LessHi all,
I am using the CYPD3177 in a custom design.
When the plug is connected, I receive the Vcc (1.8V) supply but not the VDD (3.3V) supply. The Vbus voltage is 5V and the p-channel fet remains turned off. What can do to fix the issue. The partial schematic of the PD-controller section is attached below.

Hello
Could you please tell me the Silicon ID of CYPD6128-48LQXI?

Hello,
Can I use two I2C buses simultaneously in a CCG3PA device? One is for host communication and the other is for an external DAC access.
The CCG3PA device has three I2C buses as
1. P0.0 I2C_0_SDA, P0.1 I2C_0_SCL
2. P1.0 I2C_1_SDA:1, P1.1 I2C_1_SCL:1
3. P2.2 I2C_1_SDA:0, P2.3 I2C_1_SCL:0
I'd like to use 2 and 3 together, want to doublecheck if it's okay because it has :1 and :0 suffixes.
Thanks,
Choon
Show LessHello
I would like to detect the connection/disconnection status with the HOST device and output a (GPIO) signal to the external EC.
In details, Specifically, when the PDO contract is made, the BCR notifies the external EC with a GPIO signal (Hi or Lo)
When the host is disconnected, the BCR notifies the external EC with a GPIO signal (Hi or Lo)
Q1) Is it possible to use BCR to output the above detection signal to an external EC via GPIO, etc.? Which pin can I use if possible?
Q2) Tell me about the usage of "Pin 8 GPIO_1". Is it possible to use the above detection signal?
Best Regards
