Going crasy with the Global timer on my i.MX6

Dear all.

I'm working with a Nitrogen6X which has a i.MX6 chip.

I'm trying to configure the global timer to be the timer for the scheduler of the RTOS that I'm porting to the board.

 

I can configure it the way I want but the sticky interrupt flag is always at 1 after I serve the interrupt.

The ARM Information Center states that "The event flag is cleared when written to 1." What does this mean?

I have tried to write 0 directly to the register that holds the flag (Global Timer Interrupt Status Register), I tried to write 1, I tried to disable the interrupts of the timer and the compare functionality, but nothing seems to work.

 

Thanks in advance
