Hi,

I'm facing a problem while developing the firmware for a 100W power adapter.

I programmed the CYPD3196 via SWD and J-Link. Afterwards I could not program it a second time. In openocd I get the error "DP: cannot read IDR".

I suppose I have chosen the wrong bootloader. Because I was not able to find the bootloader for the CYPD3196, I utilzed the one for CYPD3175. Is it possible that this is interrelated?

Where can I find the correct bootloader files for the CYPD3196?

Is it possible to reprogram the chip?

As we known, we can program firmware with Miniprog, 

I just want to know CCG5 CYPD5225 if can use Segger or ST Link to program hex file?

I tried Segger and STLink to programm CYPD5225  but failed.

1. Does "VBAT to GND protection" and "VBUS OCP" use the same - resistor current sensor to detect  current ? ( pin#18 and pin#19)

2.  Application note : This resistor senses the current, and if it exceeds the firmware-configured threshold, the NFET is
turned off to interrupt the current. This protects against over-current conditions caused by external faults

How to set "VBAT to GND" firmware-configured threshold to different value ?

I have questions about Configuration Parameters:

Can you please explain those Parameters in detail

1) "Dead battery"  event mask 

   this Parameter  is only useful for "dead battery" condition ? and how to use this Parameter  ?

2) Rp supported  and Current level

    what diffetent between "Rp supported" and "Current level" ?

    Both of two Parameters  seems the same for setting Rp level.

3). AMD platform type - Renoir, Rembrandt_A0, Rembrandt_B0

     How to know platform is Rembrandt A0 or B0?

4). For Rembrandt platform, the FW uses the one I2C Master (SCB) to inteface RETIMER and SOC, right?

Hello.

I want to use CY7113kit and program 140W (28V, 5A).

So, I updated to kitprog3, but the device doesn't work.

Help me, please.

Using CCG5 as the sink end, The Apple 20W or other 65W PA charge for ccg5,  a hard reset occurs when PA plugin, PD LOG has been posted.

Please help to analyze the reason.
