evkmimxrt1064_dev_video_virtual_camera samples (lite and not) do not seem to work

Hello,

 

I have programmed my MIMXRT-1064-EVK with the video over USB samples provided by the SDK but they do not work (i.e. device enumerates as a camera but does not provide the expected static picture). Using Skype, Webcamoid & Zoom I see a black image, Zoom does not even allow to start the video. I did not test with QQ but I don't think it would make much of a difference. I'm using MCUXpresso IDE v11.1.0 [Build 3209] [2019-12-12] and SDK 2.7.0 on a Linux host. I have noticed that it actually does work on Windows 10 but, alas, not on Linux Fedora.

Debugging, I see that the following code is executed every time a "USB_OTG1_IRQHandler" is invoked:

 

if (status & USBHS_USBSTS_URI_MASK)
{
    /* Reset interrupt */
    USB_DeviceEhciInterruptReset(ehciState);
}

 

Any ideas, recommendations etc. ?

 

Thanks in advance.
