USB EZ-PD™ Type-C Forum Discussions

Hi,

Software v1.0 works fine, but the newest version 3.1 is crashed on start. I have the screenshot of the error messages.
How can I fix it?

Thank you in advance

I refer to SDK - CYPD3171-24LQXQ_pb project to build our power bank project.

if If the type-c is unplugged while the power role is source, the FW will throw a APP_EVT_DISCONNECT evnet.

if If the type-c is unplugged while the power role is sink, the FW won't throw a APP_EVT_DISCONNECT evnet and throw another APP_EVT_TYPEC_RP_DETACH evnet and power path mosfet don't turn off, why? and how to solve it ?

Hello.

I'm using the CY4532 in Vconn mode.
Source caps (PD, PPS) are stored properly, but when connected to a mobile device, it can be charged at 0W ~ 2W level.
The board also produces noise.
For example, Galaxy Mobile displays Super Fast, but the charging watt is 0W (or 2W).
I wonder why the charging watt is low.

* Connection status

- Power : J2 24V
- SW1 : DC Input
- Power board : J6, J7 shorted 2-3 / J9, J14 shorted 1-2
- Main board : J2, J3, J4, J6 shorted 1-2 / J5, J7 open
- R1, R54 : 0ohm

Hi,all 

From this Datasheet Infineon-EZ-PD_TM_PMG1-S3_Datasheet_Power_Delivery_Microcontroller_Gen1-DataSheet-v05_00-EN.pdf, the description "These chips include an Arm® Cortex®-M0/M0+ CPU and USB-C PD controller",  are pd and mcu independent? I mean, if we simply want to use the pd sink or pd source function of this chip, do we need to rely on mcu to control and achieve this function? If we do not need to control the mcu to achieve this function, how do we need to achieve it?

If I have any misunderstanding, please help me to point out.

Thanks & Regards,
Jiong

Hi All，

        We transplant CC bootloader code from CCG3PA  to CCG5 . 

        When we click Utility button Program, an error happens as follows.

Because CCG3PA PD register differs from CCG5, modify CC bootloader PD contract code  as  shown in the attachment. 

Please indicate where is wrong.

Thanks

I am not familiar with Intel Elkhart lake platform,

Dose  Elkhart lake's SOC integrate MUX and PD controller communicate "type-c connection state" with SOC by I2C bus?

Customer has new TYPE C - PD requirement for  Elkhart lake platform.

1. which PD controller do you suggest for this project ? 

2. SDK has post build scripts are used to generate separate binaries, ex :  tiger lake , ice lake .. alder lake ...

    which bin can be used for  Elkhart lake platform?

I'm trying to setup my CY4531 eval kit with a PDO to source 12V.  My USB-C device is set up to accept PDO 0 and PDO 1.  I can set PDO 1 on my CY4531 to 9V, 15V, or 20V and it works fine.  But when I set it to 12V, it doesn't work.  I used the EZ-PD analyzer to monitor the PD messages.  I see the CY4531 tell the device that it has two PDOs, 5V and 12V.  I see the device request PDO 1 (12V).  And then VBUS drops to 700mV for a few milliseconds before going back to 5V and starting all over again. 

Can the CY4531 eval kit source 12V?  If it can, what am I doing wrong?  I've attached the analyzer message log for reference.

Hello

I connected the CY4500 to my PC, but the drivers were not automatically installed.

Therefore, I downloaded the file from the link below and installed it on my PC (Windows 10 64bit).

https://softwaretools.infineon.com/tools/com.ifx.tb.tool.ezpdprotocolanalyzer?_ga=2.94904474.782080597.1667780848-151091534.1639371697 However, the folder for the following drivers described in "Note:" in "CY4500 Kit Guide.pdf" does not exist.

"<Install Directory>\CY4500 EZ-PD Protocol Analyzer\1.0\EZ-PD Analyzer Utility\drivers\bin "

Could you please tell me the reason?

Best Regards
