USB FS problem while handling other interrupts

Question asked by prasad.balmukund on Jan 24, 2012
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
Balmukund Prasad
