GPIOTE & NFC not work with RTOS

[silivanov]

When using FreeRTOS, external GPIOTE interrupts do not work.

And just how correctly to use the NFC with FreeRTOS?

In examples NFC use app_scheduler for events handling such as:

> ret_code_t err_code = app_sched_event_put(NULL, 0, scheduler_ndef_file_update);
> APP_ERROR_CHECK(err_code);

I'm use SDK15 and S140 v.6.0.0 Production

Hi,

There was a bug in nfc driver in SDK15 in files hal_nfc_t2t.c and hal_nfc_t4t.c.

                              

Check if this fix helps?

[silivanov]

how does this help solve the problem?

In the examples use app_scheduler for "scheduler_ndef_file_update".

How to call this function correctly when using FreeRTOS? 

Set a flag in interrupt and call the function "scheduler_ndef_file_update" directly from the task of FreeRTOS?

And what about external interruptions of the GPIOTE?

I am not sure why GPIOTE interrupts are not working with FreeRTOS, they should, i do not see any conflicting dependency for that particular interrupt not to work. 

Sorry about the NFC question, I misread it. 

app_sched_event_put and app_sched_event_get functions are not very efficient with FreeRTOS, may be you can port the scheduler functions using TaskSuspend and TaskResume FreeRTOS API
