Can FX-3 support non-UVS device?

NTU-David · ‎Jan 14, 2021

Hi

Recently, we working on a project, it need to communicate with OCT camera and FPGA by using USB3.0.

The problem is the OCT camera can't support UVS protocol, it is using a driver making by themselves.(The driver can work on the JETSONTX2 arm64 device, OS is Linux)

When I reviewed the EZ-USB FX3 user manual, the FX3 has ARM and it can working on Linux.

Can EZ-USB FX3 install the extra diver or I need build other driver by myself ?

Or does the EZ-USB FX3 have only USB PHY mode?

Looking forward to your reply, I will appreciate that.

Hi David,

From the block diagram I see that you need FX3 to act as USB 3.0 Host to communicate with camera. That is, the middle block in the above block diagram, is EZ-USB FX3 acting as USB 3.0 Host. Please correct me if I am wrong.

If it is correct, then please note the following:

1) FX3 can only act as USB 2.0 embedded Host and not 3.0

2) We do not support Linux on FX3

3) There is a example firmware where FX3 acts as usb 2.0 embedded host to Mass storage and HID class devices. For your application you will have to make your own driver referring to the example. The custom driver you write should be able to handle communication to camera and FPGA.

example can be found here after installing FX3 SDK:

{SDK_Installation_path}\EZ-USB FX3 SDK\1.3\firmware\basic_examples\cyfxusbhost
