USB EZ-PD™ Type-C Forum Discussions

Hello

I'm using CYPD3171-24LQXQ_pb, and set CCG_TYPE_A_PORT_ENABLE to 0u in stack_params.h, then delete the whole TypeA Page in TopDesign.cysch -> Build successfully

Create a new page as I2C on TopDesign.cysch , Drag A I2C Component as master to I2C page, then assign sda to pin7, scl to pin8

-> Build successfully

Add below code to main.c after ccg_app_task_init ();

    SCB_I2C_INIT_STRUCT config;

    SCB_I2CInit(&config);

-> then Build fail, any steps i missing? Please help to check the procedure I apply, Thanks

CCG3PA Car Charger (CLA)   debug mode step by step ( step over )

we get Error: dbg.M0015   after passing  

1.   timer_start (0, LED_TIMER_ID, LED_TIMER_PERIOD, led_timer_cb)
2. instrumentation_task();

in order understand  the flow of power sdk  in crutual  go step by step to see  sequence and call reference function ( ability look on the stack pointer )

for example  which function  (app_callback )  and when  ( time line ) call by  by PD stack 

please advice ?

   why  in  power bank example this function enable pd_internal_cfet_on   and in power adapter  is disable  in pdss_mx_hal.c   file  ?????

i want  use  these function  to my application i have different functionality  (for example  i want connect LED   with FET driver ....... or any other application )   which  i need toggle  otr low/high

  Compile Time Options  Table 3: Selectable Firmware Features in stack_params.h  CCG_SOURCE_ONLY     in power sdk guide

please advice 

For the CYPD3175. We will be designing using the USB type C connector and USB-A type connector

For EMC purposes would you recommend using a Ferrite bead between the shield pins and circuit ground for both of these type connectors?

I would like to have my schematic reviewed by Cypress. Can you please provide a direct email so that I may forward the design to you.

This utility is mentioned on the Cypress USB-C Thunderbolt Reference Solution, specifically in "Step 3": "Contact Online Tech Support Case System to get the Thunderbolt device configuration utility which can configure vendor- and design-specific parameters (VID, PID, Power profiles, etc) in the CCG5 firmware. This tool will generate CCG5 BIN & HEX file"

Our application is a Thunderbolt 3 product based on Intel's Tapex Creek, which uses Cypress CCG5 part# CYPD5235-96BZXI, and Cypress Billboard part# CY7C65215-32LQXI.

my  setup

CLA  project  with boot    on CY4532 EVK  board

limitation :i dont have option to debug   because it is  not noboot project    i do not have option connect UART because all possible GPIO is taken by example

therefore  add  LED  to indicaton  status  USC TYPE A cable

on main board  j8 debug connector add LED on p2.1

on main  board  J9  connecting phone  the charge is  starting  but when i trying  to get info  from type a device  it failed

in callback timer  add  following code

                const bc_status_t* user_param;

                 user_param=bc_get_status(TYPE_A_PORT_ID);

                if (type_a_is_idle())

                {

                    WEIZ_DEBUG_PRINT(WZ_APP_EVENT_FLOW, "[%s] USB Type A connected Charge mode [%d] \r\n", __func__,user_param->cur_mode);

                    gpio_set_value (FW_LED_GPIO_PORT_PIN, false);

                }    

                else

                {

                    WEIZ_DEBUG_PRINT(WZ_APP_EVENT_FLOW, "[%s]USB Type A Disconnected \r\n", __func__);

                    gpio_set_value (FW_LED_GPIO_PORT_PIN, true);

                }

when i plugin  cable  expected  light  off   when unplug  the cable expected  light  on   it never happen

Q1 : what functionality need to add  to see plug/unplug changes on port A

The customer needs the information formulated by PD package to communicate with the host ,if not the equipment is not working properly.

Hello

I connected CCG1 and CCG2 with reference to Evaluation Kit Guide P.22, but the device of CCG2 is not displayed.

Is there a solution?
