Hi,
Many of the examples use Vender commands in FX3 SDK. For example, UsbSpiGpioMode implements Vendor Commands for SPI flash operation. You should take a look into this example projects.

Dear Eddie,
I know FX3 SDK,but when My app is based on V4L2 framwork, I cannot know how to send a customized control message, e.g. vendor or extention unit command.
In V4L2, all standard UVC cmds are supported, but I want to send vendor request or extension unit command, does Cypress know V4l2 METHOD to do for this case?

Hi,
We only provide related API in CyAPI.lib. I'm not sure if it can work with V4L2.
