RTOS: Syslink GatePeterson_enter() blocking other interrupts.

Tool/software:TI-RTOS

Hello,

I am having a problem where the function GatePeterson_enter() is called and invalidated the cache for long duration, up to 5ms seen. During this time, none of my interrupts can be served. It is a major problem here as our motor control SWI is not executed as expected every 300 micro-second (clock timer triggered).

I have also found that the event dispatched in the sysbios is also no served during this time.

Have you ever seen such a problem ?

Thank you,

Vincent
