Hi,

I am using STM32F207xx for my application.

In my Application,I am using OTG_FS ,FSMC & DMA for TFT Driving.

If i Disable all other interrupts except for USB_FS,then USB  works fine.

But if all other interrupts(USB_FS included) are active then USB_FS is getting Stuck.

I am having 3 DMA,1 Timer interrupt(80 /sec), & USB_FS interrupts.

Timer interrupt is coming 80 times in a second.For our application I can't reduce this.

Any body having any idea about this??

Thanks

Regards
