Hi,
We are trying to start a timer in one shot mode and have it toggle the output pin a single time on overflow but it doesn't work. If we keep the same configuration but change the mode to auto-reload it works but then we have multiple pin toggle. Note that we always get the interrupt successfully even if we don't get the pin toggle. See how we configure the timer below.
Any advice would be appreciated.
int def_on = 1; // Set the PORTIMERPWM output pin and select negative pulse for pulse mode
int toggle = 1; // 1 = Toggle mode
int trigger = OMAP_TIMER_TRIGGER_OVERFLOW; // 1 = Trigger on overflow
int autoreload = 0; // 0 = One shot timer
gptimer = omap_dm_timer_request_specific(4);
/* Setup interrupt */
irq = omap_dm_timer_get_irq(gptimer);
irq_request_ret = request_irq(irq, (void *)&irq_handler, irqflags, devname, dev_id);
omap_dm_timer_set_int_enable(gptimer, OMAP_TIMER_INT_OVERFLOW); // 1<<1 = overflow
/* Set mode and start timer */
omap_dm_timer_set_pwm(gptimer, def_on, toggle, trigger);
omap_dm_timer_set_load_start(gptimer, autoreload, 0xff000000);
