Interrupts in Arduino Sketches on the IoT2020

Hi

According to the GPIO assignment document interrupts are available on pins 2 and 3.

I am trying to use a pin interrupt in an Arduino Sketch on the IoT2020 but cannot get it to work.

Has anyone has had any success with attachInterrupt(2, isr, CHANGE); or attachInterrupt(3, isr, CHANGE);

You might be bitten by a mistake in the firmware that we will be working around in the next image version via a kernel patch (https://github.com/siemens/meta-iot2000/blob/master/meta-iot2000-bsp/recipes-kernel/linux/files/0027-iot2000-hack-Work-around-DSDT-mistake.patch).

I've you feel brave enough to build your own image, try creating it according to the branch https://github.com/siemens/meta-iot2000/tree/jan/staging. "pip3 install kas" does not work yet, you need a manual installation of https://github.com/siemens/kas - or use the Docker path.

Sir,

I've gone through your github file. But I couldn't find the file "drivers/gpio/gpiolib-acpi.c". I'm not able to find the "gpio" driver under the "drivers" directory in the image I'm using (downloaded from Siemens website).

Kindly help me regarding this issue.

Thank You.
