Hello,

The parameters required for fwDownload.exe can be determined by using the command-

fwDownload.exe -h

If you're using the CY7C65211 part, please set the appropriate PID based on your current configuration. The default PID should be 0x0002 in UART mode and 0x0004 in I2C/SPI mode.

Best Regards,

Sananya

How is the Config file generated? Not an ASCII file.

Is there any documentation?

What is fwDownload.exe and why do we need it? Is the part programmed from the factory?

Hello,

The configuration file is generated with the USB-Serial Configuration Utility, you can refer to section 2.3.6 Cypress USB-Serial Configuration Utility User Guide which you have pointed out above. The fwDownload.exe is a command line utility used to change the device configuration for single or multiple devices. The part already has a fixed firmware and default configuration and can be also programmed with the USB-Serial Configuration Utility which is a GUI based tool.

Best Regards,

Sananya
