First : I'm using pascalio, on a Pi2 model B.

Just modified bcm2708.pas :
   GPIO_BASE = (BCM2708_PERI_BASE + $003F0000); // GPIO controller
and
   mem_fd := FpOpen('/dev/gpiomem', O_RDWR OR O_SYNC);

Now I can run my app as user 'pi'.

Thanks.

According to Bo's post 
(http://lists.lazarus.freepascal.org/pipermail/lazarus/2015-October/094438.html) 
GPIO_BASE depends on where the app runs.
I'm going to look for a way to detect which device the application runs 
on so I can automatically switch the GPIO_BASE.
Suggestions ?

Koenraad.
