Hello everyone,

I want use USB port as USB OTG but firmware do not support this mode, instead Device and Host modes separately. Where can I read example of USB OTG driver implementation for free?

Thanks in advance

OTG is implemented in the pre-Cube, SPL version of the USB drivers, but be prepared that they are written in a very different style from Cube.
