Is there a USB library for HPS of Cyclone V SoCFPGA?

I'm planning a project to create a device based around a Cyclone V SoCFPGA. It will use the HSP USB as a USB device that connects to a host computer. I'm trying to find a USB library for this chip. I have examined the HWLib downloaded from Intel and it contains code for many HW peripherals but not the USB controller. Does anyone know of such a library? I want to use it with an RTOS (still to be chosen) but could adapt a baremetal library if necessary.

One thing I should add is that most of the RTOS's I've looked at so far also lack support for USB device mode.

    I'm very fond of Linux, it's my preferred desktop environment. However, for this application I need something much much smaller for cost - 1MB QSPI instead of SD-Card - and for performance - executable and data that will all fit into L2 cache, so I'm looking into RTOS or baremetal solutions.

    The USB stack from HCC seems like my best option so far.

    Hello,

    there is no USB device support in HWLib.

    You can use Linux to get the full support of USB devices. When you compile your Linux kernel, you can find plenty of USB drivers when using menuconfig to enable/disable your system drivers.

    Thank you

    Hello,

    I have searched around and couldnt find any RTOS or bare-metal application for USB.

    Thank you
