USB MFS, NVIC Priorities -- what is recommended setting

Hi

 

I read through the manuals and posts but am not certain on the priority settings in the NVIC. Right now we have the USB NVIC defaulted to 4; I think this what was from the example code. I am seeing missed interrupts for the call backs for the USB stack and was thinking maybe we have a problem with the priority of other interrupts. The other interrupts are from the PIT0 and FTM0 these are set at 0xB0. I am assuming that higher is a lower priority.

 

Has anyone else experienced USB MFS failures based on flash drive or based on 'other interrupts' at the same?

 

Thanks

 

Robert
