I am trying to get a starterkit for linux development working. The kit consists of a PicoCOM 1.2 and a StartInf1 board v.1.10.
Looking at the documentation provided at F+S website, things do not match.
The main cause is from my understanding that the StartInf board is the one for the (old) PicoCom (please see attached photo).
My problem is that I cannot get certain GPIO pins running.
1) PicoCOM 1.2. GPIO reference card says pin 69 is GPIO_G and is accessible through /sys/class/gpio/76. This pin connects to StartInf J11_13 and works as expected.
2) PicoCOM 1.2. GPIO reference card says pin 70 is GPIO_H/PWM and is accessible through /sys/class/gpio/4. I can export this gpio, assign direction "out" and set values, but the voltage on J11_14 does not change.
1) Is the routing of pins different for this special combination of Picocom 1.2 and old startinf board?
2) If not, what could be the reason for not getting pin 70 to work?
Thanks and best regards,
