Hi,

I want to use the IO extension in my python application (used Hardware: IOT2050, FS02, Example_Image_V1.2.2). Unfortunately this works only when I start python as sudo.

I tried to run the example IOShield.py from this forum:

If I run sudo python IOShield.py it works as expected.

I also tried to run mraa directly in the command line and get the following error:

mraa-gpio get 12
free(): invalid pointer
Aborted

Again with sudo it works fine:
sudo mraa-gpio get 12
Pin 12 = 0

Has anyone a idea how I can fix this?

Tanks in advance!
