USB EZ-PD™ Type-C Forum Discussions

I have a custom board with the CYPD3177. When plugged in it only receives power from the power supply with the usb cable in one orientation, when it's flipped there is no power.

Is this the proper function? Or should it work regardless of cable orientation?

Tested with multiple power supplies and cables

Thanks

Hello everyone,

I have developed an active USB Type-C cable with a redriver from Texas Instruments and I am using the CYPD2105-20FNXIT as an e-Marker. According to the data sheet of the Re-Driver, the registers for setting the gain and other parameters can be configured via the I2C interface. In the datasheet of CCG2, the CYPD2105 is used for active cables and is used as a master to program the slave, the redriver, via the I2C interface.

I've lost track a bit, because the CCG2 datasheet says that the firmware from the CYPD2105 can be updated via EMCA CC Bootloader with Application firmware, i.e. according to my understanding with the help of CY4532 CCG3PA EVK's Power Board (hardware) and EZ PD Configuration Utility (software). However, it is not clear to me how I can use the EZ Configuration Utility to program the re-driver (slave). I have now done some more research on the Infineon website and found PSoC Programmer. There you can also select the CYPD2105 device there.

My question now is how can I use the CYPD2105 to program the re-driver. What is the right way? Does it work via the EZ-Configuration Utility with the CY4532 CCG3PA EVK or via PSoC Programmer and MiniProg3/4? Or is there another way? Which software and hardware is required?

Greetings

Hi,

I'm referring to this conversation; https://community.infineon.com/t5/USB-EZ-PD-Type-C/Re-Load-via-I2C/td-p/149672 .

We have a custom HW that has a CYPD4226 IC in it. We would like to have the capability to program the device by the application processor through the internal I2C bus instead of having to connect to the device through SWD interface. The application processor is running Linux/Ubuntu. Is there a ready-made application/tool that could do the trick? Can you share the application/tool?

Thanks,

Hi Infineon Team，

使用EZ-PD configuration 修改HEX - PDO后，无法报错，提示芯片“The firware file selected has different silicon id. Do you want to continue?”，再提示报错错误，更换软件版本问题依然存在，固件客户一直在使用，可能是什么问题？

如图显示 对EZ-PD™ CCG5进行烧录，

烧录软件是psocprogrammer3.29.1，编程器是miniprog3，pass、powered、connected均绿色显示后收录 等了很久跳出这个报错 请问可能是什么原因导致的 按照提示进行了排查没发现问题

Hello Support,

Thank you for your ususal support.

I have a question of CCG3.

Does the CCG3 support Embedded Display Port on AlteranteMode??
