bonescript DigitalWrite error: Unable to write to /sys/class/gpio/gpio60/value

[in...@fabianalthaus.de]

Hello I am experimenting with the pocketbeagle, 

and i try to write a normal digitalWrite to a gpio pin with my node script.

i am able to get button input signals and analog read. 

Anyway when i try to use: 

b.pinMode(pin, b.OUTPUT);
b.digitalWrite(pin, b.LOW);

i get the message:

error: Unable to write to /sys/class/gpio/gpio60/value

the pin seems to be owned by root user, is this the problem?

 1 root gpio    0 Dec 13 12:57 gpio60 -> ../../devices/platform/ocp/4804c000.gpio/gpio/gpio60

how can this be solved with a beaglescript from nodejs app?

thank you for any help! i am hitting a wall at the moment.

Well... The brute force method is likely to run your script via sudo...
The other method... Might be to modify your user account to be a member
of the GPIO group... (Hopefully the group has full R/W access).

You should be part of the gpio group, double check via:

debian@test-bbb-1:~$ cat /etc/group | grep gpio
gpio:x:995:debian
