Hello!
In a simple test software:
In gpio36 I connect a 5Hz square signal. The program works OK but about 8 hours later, the signal is not detected. if I read the signal with “le_w_pulsos_Read();” I see how this signal chages, but the callback function does not execute.
But when te program stop working properly, so the gpioservice logs also stop.
In this situation if I change the other GPIO38 (not gpio36), then all work OK again!
Does it work if restarting the application?
mmm … I don’t remember …
You might also consider to use gpio interrupt on kernel driver
Yes, if retarting the application, it work fine.
Okay I’ll try … I’m not a Linux expert.
you might also see the sample application and see the callback function Pin22GpioSignal() :
/**
* @file gpioPin.c
*
* This is sample Legato CF3 GPIO app by using le_gpio.api.

/* Legato Framework */
#include "legato.h"
#include "interfaces.h"
static int Pin22 = 22;
static void Pin22ChangeCallback(bool state, void *ctx){
LE_INFO("State change %s", state?"TRUE":"FALSE");
LE_INFO("Context pointer came back as %d", *(int *)ctx);
show original
The kernel driver is for modem core GPIO only.
