Hey,
I am working with the Matter light bulb sample from the 2.9.1 SDK, which I have modified to support the occupancy cluster. (nRF-52840 and nRF-52840DK)
This worked fine on version 2.5.0, so I tried to follow the migration guides and implement my custom changes to the new SDK.
While the image builds successfully, there is no Bluetooth beacon, serial communication or any functionality at all. The debugger gets stuck in this IRQ-lock function:
FUNC_NORETURN __weak void arch_system_halt(unsigned int reason)
{
ARG_UNUSED(reason);
/* TODO: What's the best way to totally halt the system if SMP
* is enabled?
*/
(void)arch_irq_lock();
for (;;) {
/* Spin endlessly */
}
}
The only interrupt related change I made is in SensorMeasureHandler() for the occupancy functionality:
void AppTask::SensorMeasureHandler()
{
uint64_t now = k_uptime_get();
uint64_t motion_time = pir.GetLastTdTime();
// Waiting for the hold-up time to expire
if (now - motion_time < kOccupancyOccupiedToUnoccupiedTransitionTimeMs)
{
// Set Occupancy true
chip::app::Clusters::OccupancySensing::Attributes::Occupancy::Set(kOccupancyEndpointId, chip::app::Clusters::OccupancySensing::OccupancyBitmap::kOccupied);
}
// Checking the logic level after hold-up time expires (is it inactive?)
else if (pir.GetTd() == false)
{
// Set Occupancy false
chip::app::Clusters::OccupancySensing::Attributes::Occupancy::Set(kOccupancyEndpointId, 0x00);
}
else
{
// Reset the hold-up time
uint32_t pins = BIT(td.pin); // Sensor TD pin number
::td_activated(dev, &cb_data, pins);
}
}
td_activated() mainly resets the timer:
void td_activated(const struct device *dev, struct gpio_callback *cb, uint32_t pins)
{
uint64_t now = k_uptime_get();
bool pd_pin = gpio_pin_get_dt(&pd);
last_td_time = now;
last_pd = pd_pin;
}
This worked fine with the old SDK, but I can't see what needs to be changed. I appreciate any help.
