USB EZ-PD™ Type-C Forum Discussions

Hi there,

In CCG7DC webpage has a reference "Test Report 65W CCG7D 2C Buck Solution Board with By Pass FCCM",

Is there schematic and Gerber file we can provide to use?

I know in document there are sch and gerber pics, but it's roughly and not much useful

Thanks 

我使用的是 CYPD4226 芯片，我在笔记本的例程中使用了 noboot 项目，最初使用 miniprog3 进行编程调试，但它不可用于现场升级。 我发现笔记本的项目也有 i2c 引导项目，我已经阅读了有关引导加载程序和可引导加载的文档。 现在我想使用不同的MCU并通过I2C接口进行现场升级。

我有以下问题：

1. 该芯片可以与其他MCU通信并现场升级吗？

2. 如果是，你能指导我怎么做吗？

Hi,

I have the CCG3PA EVK (CY4532). By default, it is configured as source. In EZ-PD Configuration Utility, I see the "Port Role" set as "Source". I am trying to set the EVK to a sink-only configuration to prototype my application. However, the drop-down menu is greyed out so it won't let me change the option away from "Source".

1. How do I get EZ-PD Configuration Utility to provide the "Sink" option since it is greyed out by default?

2. My sink configuration will request only 1 sink profile when connected to a multiple source PDO device. Will adding a specific "Sink PDO" in EZ-PD Configuration Utility be the solution? Right now, there are no Sink PDO options displayed, but I am assuming it is because the "Port Role" is set to "Source".

Thanks,
Jonathan

Hi,

Gatkex Creek's FW update tool for Mac was working over libusb, when customer would like to install it by manual that which version of libusb is required?

Is it possible of IFX to repackage FW update tool with libusb of of static-library? If it is possible, end customer will not need to install it by manual when customer's MacOS no libusb.

Hi Mohamed Rahmathulla,

Thank you for your answer. 

Thanks a lot for successfully solving the above problems under your guidance.

At present, I need to implement a firmware update function. Through reading the document, I have learned about bootlader and Bootloadable. Can I upgrade firmware through IIC only by using bootloader?

If so, which routine should I refer to to implement this part of the function?

Also, I encountered this error while compiling the official routine, and I don't know how to solve it.

Thank you again, you're really great.

Thanks & Regards

Hello.

I am developing Microdisplay with USB-C port (based on CCG3). The display should act as UFP and Sink, it can be powered and receive Display-data through the C-port of the laptop.

Is there a specific chip that acts only as UFP and Sink, or do I have to buy the DRP chip and then program or configure it?

Thanks a lot.

你好，

我正在开发有USB-C型接口的微型显示屏(基于CCG3)。显示屏应该作为UFP和Sink，它能通过笔记本电脑的C口接受供电和接受视频数据。

是否有一个特定的芯片只作为UFP和Sink，或者说我必须买DRP的芯片再对它进行编程或配置？

谢谢

Is Host SDK able to support Raptor Lake ?

which SDK project can be used for Raptor Lake ?

which config file  ( icl / rkl  / tgl  / tbt ) can be used for Raptor Lake ?

Hi there,

Recently our customer has concern if CCG3PA can pass "USB Power Delivery Compliance Test Specification"

for power bank mode, below pic is test result of other solution,

Is there any document can provide? thanks
