About CYPD2122-24LQXI Plating Ball

Originally, there are 2 kind of plating ball?

　NiPdAu

　PureSn

Was this from the beginning?

Or is PCN on the way?

No such PCN could be identified.

Q: where  i could  find  address of  each part  in FLASH Memory

Q : when  i load hex file  i update only fw application or also configuration table  area ?

Hi，

When I used mini B cable to connect PC and CY4531 CCG3 Evaluation board,at the same time, I powered on CY4531, Device Manage of PC can detect device,displaying "USB-serial adapter1" and "USB-serial(dual channal) vender MFG". But on the EZ-PD Configuration Utility, it can not find the HID/USB-serial Bridge devices and displayed "

0 HID devices found

0 USB-Serial Bridge devices found

No HID/USB-Serial Bridge devices found

Device Discovery failed"

So any ideas? And must I use miniprog3 to debug program?

If I use miniprog3, can the EZ-PD Configuration Utility detect device?

Thanks.

Hi there,

I have something a little strange happening when I attempt to read/write a new configuration to the CYPD3120.  It only occurs when using the bootloader to read the configuration on the currently active firmware.  It also has a similar problem when trying to use the bootloader to update both firmwares at the same time.

In short, it looks like the CYPD3120 enters the bootloader with no trouble. 

The Message window reads:

Starting CCG configuration read over HID interface.

Jump to Boot command successful.

It will then wait there for around 30 seconds before giving me a failure messagebox "Configuration read failed".

The Message window at this point shows:

Error: Failed to find handle to HID Device

Error: Failed to read CCGx configuration.

Error: DLL call returned error while reading the configuration

However, if after the Jump to Boot command successful message I power cycle the CYPD3120, it reads out the configuration with no problems.

Reading the configuration of the firmware that is not currently active has no problems at all.

Anyone know why this might be or how to fix it?
