USB EZ-PD™ Type-C Forum Discussions

Hello community!

I'm using CCg3pa for my custom design.

In our design CCg3pa can only act as BC1.2 and PD SNK/UFP.

We have a requirement here to read the live D+ and D- voltages ( Similar to vbus_get_value(G_PORT0); /*return present VBUS voltage in mV */ ).

As per below snippet captured from CCG3PA Data sheet I can infer that the Dp/Dm lines voltages can be accessed using available ADC. Correct me if I'm wrong.

So Can anyone please provide me insights to read Dp/Dm live voltages using an API ?

if reading live voltage is not available,

As per below snippet will reading states of Dp/Dm lines using respective structure and tracking if they're in certain range can be done ? will this structure help me achieving our requirement ?

Thanks and regards,

Pranay.

Hi,

      I want to download firmware by usb serial cable(usb to I2C). The cable use common CH341 chip.  But EZ-PD Configuration Utility can not find device. The schematic is the same as Jetson AGX Xavier of Nvidia. The connection of the device is below. Please tell me what the special attention.

Thanks.

For EZ-USB HX3PD:

1: How to setup idle mode or suspend mode for host? is it any host API  to setup this USB controller idle mode or suspend mode?

2: Is it possible to switch off the power supply of DS port? 

Many thanks!

Hi to all,

right now I try to get the hang on the PSoC creator but I'm stuck at an issue. I use the CYPD5126-40LQXI_notebook example and as long as I use the "dummy_boot" bootloader to link all works fine. However, if I use the "i2c_boot_3_2_1_56_0_0_0_nb" bootloader (a dual application bootloader) the code generation fails once "cyelftool -M" is called to "m"erge both copies of the firmware into one hex file because both versions "overlap".
I think the root cause is the invocation of "cyelftool -B" beforehand for both copies of the firmware, both with "--flash_offset 0x00000000" which, by my guess, places both firmware copies right at the start of the flash ROM (and doesn't even account for the bootloader which should reside there).

I hope I just forgot to set an offset somewhere either in a header file or a setting but I can't find it.

Thanks for the help.

Hello There,

Hope you Doing Fine.

I Have some Question Regarding CYUSB3610.

1. How Many Type-C Wires Required?

2. How Much Power it Can deliver and Distance.

3. Speed and Distance.

4.  How many Ethernet Wires Required?
Plz Help

Please provide us the VIF file for Dock SDK.

EZ-PD™ CCGx Dock Software Development Kit (SDK) (cypress.com)

Used board : CY4532 EZ-PD

Used program : EZ-PD Configuration Utility

Output spec : PD 20V, PPS 3A or more

Symptom :

1. After setting the output PD 20V / 3.25A, when checking the output, PD 20V / 3A is applied.

2. After setting the output PPS 3.3V~11V / 4.05A, when checking the output, PPS 3.3V~11V / 3A is applied.

How can I use an output of 3A or higher?

About Microsoft modern standby,

Does Cypress Type-C host design relate this function?

Does need CCG firmware to implement or SDK already supported?

Thanks,
