RE: nrfx timers - unhandled interrupt on CPU0

Marco Russi — Fri, 15 Dec 2023 10:33:17 GMT

Thank you Jorgen, I added the following

IRQ_CONNECT(DT_IRQN(DT_NODELABEL(timer2)),

DT_IRQ(DT_NODELABEL(timer2), priority),

nrfx_isr, nrfx_timer_2_irq_handler, 0);

and it is working now. I was close but not enough... :)

Thanks.

Hi,

[quote user=""]

I tried to add this piece od code

Fullscreen

IRQ_CONNECT(TIMER2_IRQn, 0, timer2_interrupt_handler, NULL, 0);

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

IRQ_CONNECT(TIMER2_IRQn, 0, timer2_interrupt_handler, NULL, 0);

Since you are using the nrfx timer driver, you should connect the interrupt to the interrupt handler defined in the nrfx driver, not to the event handler in your application. The interrupt handler in the driver will check/clear the events from the peripheral and pass appropriate events to your application event handler when needed.

Either use the macro as shown in nrfx_timer sample in upstream Zephyr, or write out the name like it is done in the nrfx sample in Zephyr.

Best regards,
Jørgen
