Bulk transfer for USB host camera interface

pjanco — Thu, 13 May 2021 19:35:19 GMT

Hi,
I am trying to connect a face recognition camera to USB host interface on EVK1060 board and it is not functional with SDK example "host_video_camera_freertos". By debugging the code I figure out that a camera support only "bulk" transfer type and SDK example have implemented only "isochronous" transfer type.

Can you provide an example or any useful information for bulk camera host?

Regards, Peter.

Hello Peter,

The USB examples on the i.MXRT1060 are a bit limited and offered as proof of concept. USB video/audio can get a bit tricky, there are some threads on this topic on the communities but most are focused on USB audio rather than USB video, and there is not a definitive document or example for reference.

My apologies for the inconvenience.

Regards,
Gustavo
