IOWR_ALTERA_AVALON_TIMER_PERIODL (INTERVAL_TIMER_BASE + 0x8, 0x6500);

IOWR_ALTERA_AVALON_TIMER_PERIODH (INTERVAL_TIMER_BASE + 0xC,0x1dcd);

IOWR_ALTERA_AVALON_TIMER_CONTROL (INTERVAL_TIMER_BASE + 0x4, 0x4);

run=IORD_ALTERA_AVALON_TIMER_STATUS(INTERVAL_TIMER_BASE);

Timer macros already include the offset.

The correct usage is:

IOWR_ALTERA_AVALON_TIMER_PERIODL (INTERVAL_TIMER_BASE, 0x6500);

IOWR_ALTERA_AVALON_TIMER_PERIODH (INTERVAL_TIMER_BASE, 0x1dcd);

IOWR_ALTERA_AVALON_TIMER_CONTROL (INTERVAL_TIMER_BASE , 0x4);
