USB EZ-PD™ Type-C Forum Discussions

Looking to reflash a virgin CYPD6228-96BZXI attached to a notebook host as a repair. The old IC failed and forcing bios updates does not seem flash the firmware as I had hoped. I've obtained the 64kb firmware from an encapsulated bios update and have SWD access.

It seems that PSoC Programmer gives the following error when attempting to load custom firmware: 

| Hex File parsing failure. Checksum record does not exist

What is a guaranteed hardware/software combination for me to reprogram this device? Thanks.

Hi, I am working in get the control of the CYPD3177 using only I2C communication but I am not sure about which components I need to change in the schematic for this application. I only need to control the PD profiles via I2C, I would like to know if someone had done it before that can help me with the schematic circuit. Thanks in advance. #CYPD3177-24LQXQ #I2C Show Less

Hi All, I'm trying to play with CY4534. When I connect it to the USB-C power supply (pr PC host), I see only 5.178V at the terminal outputs, no matter what settings I use with potentiometert switch (from 1 to 5). No jumpers installed, power supply can output up to 20V via USB Type-C. I tried to connect CY4534 to the host and check with PD BCR HPI unility what is going on with the registers, but when I try to install the HPI utility, it says I need to install PsoC Programmer 3.28.6 or later. Searching through Infineon web I can locate only PSoC programmer 2.7 and neither CYPD3176 not CY4534 page doesn't provide any links to the correct version of PSoC programmer. So highly appreciate your comments. Best regards, Ilya Show Less

 

I am using power sdk - CYPD3171-24LQXQ_pb project,

I have to set different of respond ( REJECT or ACCEPT )  to Power role swap command according to different conditions.

I add debug uart msg in swap.c - eval_pr_swap function.

but I found that when ccg3pa receives a  pr_swap command, it does not execute eval_pr_swap function, why?

I'm using CYPD3175 in my design. I use the same schematic here. https://www.power.com/sites/default/files/documents/der-628_18watt_usb_pd_charger_using_innoswitch3-cp_and_cypress_controller.pdf I have no clue whether the pre-loaded FW already does the job or I should flash an FW into it. All I see while plugging different phones, is 5v at a maximum 450mA. The voltage never changes to 9v and I see voltage changes on CC lines. I checked VDDD and VCCD, and they're as supposed to be, meaning the internal circuits are fine. Show Less

For an CCG3PA application with direct feedback control, is it possible to correctly repurpose Pin 12 (Load enable control) and what limitations does it have? We were able to reuse it for communications but when the USB output is disabled with "dpm_typec_command(port, DPM_CMD_PORT_DISABLE, NULL)" pin 12 stops being pulled up to VDDD and (in our HW implementation) lowers to around 2V. Is it possible, for example, to re-enable it's internal pull-up resistor without afecting the function of the output port (by keeping it disabled)?

Hi! We are updating our manufacturing setup and would like to automated the programming of the .hex file that we today do manually via PSoC Programmer. Found a couple of posts on how to use PPCLI for PSoC4 and PSoC 6. Is there an existing guide and example on how to program a CYPD4226 using more or less the project from the EZ-PD SDK via command line a c-sharp project for instance? Or any specifics between the generic PSoC4 examples and using it for CYPD4226? Cheers Olof Show Less
