Issues migrating from v2.5.0 to v2.9.1

[rwahidi]

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 in the apptask.cpp:

This worked fine with the old SDK, but I can't see what needs to be changed. I appreciate any help.

Hello,

Can you share the necessary steps to reproduce this? Your shared code does not have all the needed definitions. So far I have added the occupancy cluster in ZAP tool, but since I am missing definitions for several objects and functions in AppTask.cpp, I'm not able to build the project.

Just as a sanity check: does the unchanged light bulb sample boot properly?

Best regards,

Maria

[rwahidi]

Hello,

the unchanged sample works as expected and can be commissioned.

I have modified the apptask.cpp and I have created a new file BGT60.cpp/BGT60.h with functions related to the sensor. This was functional in SDK v2.5.0. After porting these changes to the new SDK and getting rid of the building errors, the board seems to be stuck in some state.

I have edited the original post to include the full apptask.cpp and related functions.

While debugging, stepping over the initialization function of the Sensor bgt60.init() causes the same IRQ lock. So my best guess is that some of the GPIO configures or interrupts are faulty.

Thank you and best regards,

Wahidi

[rwahidi]

Okay I have found the line that causes an assert, it is my custom bgt60.cpp file. There is no additional info.

55	    ret = gpio_pin_configure_dt(&td, GPIO_INPUT);
ERROR: Command aborted. See the output window for additional details.

[rwahidi]

Still no luck unfortunately, maybe someone can check my custom overlay for compatibility with the hardware model v2?

Hello,

Thank you for the update.

I have reproduced this now, and will start debugging. I'll report back with my findings as soon as I have some. I will strive to get back to you by end of Tuesday.

Best regards,

Maria
