USB EZ-PD™ Type-C Forum Discussions

Hello everyone i made PCB design based on the reference design PB-811 and CCG3PA Car Charger Reference Design using Southchip i changed CYD1775 of car charger to CYD1771 so it will work as power bank i connected both CCG3PA with I2C as the design of this  reference design ACT2861-201-REF03 but the problem is the exemple code in PSOC creator is based on PMW between CCG3PA and BUCK/BOOST and not on  I2C as on both reference design.

can i please have the code exemple of https://www.cypress.com/documentation/reference-designs/ez-pd-ccg3pa-usb-cpps-power-bank-solution-using-qorvo-formerly

so i can start with ?

In an x 2 configuration, shall the DP_SYS <-> DP_TOP/DP_BOTTOM passthrough be omitted and the lines connected directly?

We intend to dynamically support two configurations:

Config 1: First connector in USB 3.2 Gen1 x 2 mode, second connector in USB 2.0 mode

Config 2: Both connectors in USB 3.2 Gen1 x 1 mode

Is it possible to use the CCG6DF to dynamically switch between these two configurations? If not, can you suggest another solution?

Hi everyone,

I use in my project CYPD3120-40LQXI_dp_dongle SDK.

When I connect my PC to the board, the MOSFETs open. I want to disable it.

The function is responsible for this dpm_start(), but I could not find where it is determined.

I will be grateful for any help.

Best regards,

Nazar

Hi All,

One of my project I am using Cypress device (CYPD3175) device. I need to disable the CC-firmware update by disabling the option in the EZ-PD Configuration Utility -> Read from Device -> Device Parameters -> Enable Firmware Update -> change to “NO”. Then File -> Save to Firmware file -> select the firmware file as .cyacd (saved this as final firmware for pre-production).

Concern is if I update this final firmware (firmware update changed to “No”) through Tools -> Firmware update in the EZ-PD Configuration Utility, flash is not updating successfully, instead I am getting the error as “ Firmware/configuration upgrade not completed. Refer to the message window for details.” The messages in the message window is shown below for your reference. After this if I tried to read the device, I can’t able to read the device (it is disabled, but flash is not updated successfully). Will you please help on this. Waiting for your reply. Thanks in advance.

Design is based on Tapex Creek using Cypress CCG5 part# CYPD5235-96BZXI, and Cypress Billboard part# CY7C65215-32LQXI.

1. Can the Cypress devices in question be programmed in mass (off board) prior to circuit board assembly? Cypress Doc 002-22328, page 4 states that a programmer is to be used using the SWD lines, which is fine for development (which we have done) but this is unacceptable for mass production.

• Please clarify how off-board programming is handled for both devices for mass production
• Please clarify how these devices FW could be updated in the field after shipping- specifically, how is an update performed over the TBT3 connection via the host computer?

Thanks in advance!

Hi everyone,

I use  SDK CYPD3120-40LQXI_dp_dongle and want a little change  your code with help PSoC Creator 3.3.  But I don't now how. Could you help me?.

So, my question sounds that:

How to disable alternate mode and connect USB USB interface to control device from computer?

Hello,

I was wondering if there is an orcad symbol available for this part.

Hello

CY4533 and adapter connected.For BCR(CY4533), when requesting PDO, "Communication Capable"=NO is returned.
Q)

Is there no other way but to use CCG3PA(as Sink), etc. instead of BCR in order to realize communication by being powered by USB PD?
If there is any way I can use BCR with Communication Capable=YES, please let me know.

Best Regards

Hi,

I would like to get CC pin voltage in order to check the cable type. Any API to get the CC pin voltage?
