Hello,
I ned to use GPIO40 of my custom electronic board as ChangeEvent to detect a change edge in this pin.
In Legato:
le_i_o_2_int_AddChangeEventHandler(LE_I_O_1_INT_EDGE_FALLING, le_i_o_2_intChangeCallback, NULL, 0);
But when te program runs, the logs indicate an error:
Feb 11 11:57:53 | gpioService[820]/sysfsGpio T=main | gpioSysfsUtils.c WriteSysGpioSignalAttr() 180 | GPIO /sys/class/gpio/gpio40/edge does not exist (probably not exported)
Feb 11 11:57:53 | gpioService[820]/sysfsGpio T=main | gpioSysfsUtils.c gpioSysfs_SetChangeCallback() 606 | Path doesn’t exist to set edge detection
Are there any restriction on this GPIO? is it not possible events in this GPIO? Is there documentation about this GPIO restrictions?
Thank you
