When SOF interrupt enable and USB enable, Why SOF Interrupt still occurs after disconnect with PC?

PC occurs SOF signal, OMAP SOF interrupt will not occur after OMAP disconnecting with PC。

Thank you!

Hi Cherry,

This could mean that OMAPL138 is configured as Host. Did it connect to PC successfully ?

Can you let me know the OS being used ? And how do you check the SOF interrupt ? And if any logs available.

1. OMAPL138 is not configured as Host. (USB0_ID is not driven Low.)

2. It connected and disconnected to PC successfully.

3.nucleus OS.

4.Check SOF interrupt by INTSRCR.USB[3] in interrupt handle function.
