Hi Willy ,

thanks for your reply.

I am sure that my timer is working( TIMER0_1), because I checked the
register , it was counting , and the interrupt flag register also
gives out interrupts periodicly.
the problem is that it seems that the program just toggles here:
interrupt rountines, gic_ack(), interrupt handle
functions.............., my simulation enviorment also tells me that
invalid iqr id (0x21) is writen to EOI(end of interrupt).
I am also sure in the interrupt routine I clean the interrupt flag of the timer.

so this is roughly my situation.

does anyone have some idea?

thanks,

regards,

yang
