Hello
I did seven programas in python to measure the analogues inputs in my beaglebone black.I created one service for each script. I only have 4 signals connected to analogues inputs the other three are disconnect, but all services are running.
In my application I need all scripts are running automatically when the beaglebone black boot.
All scripts works well for a few days measuring the values in each analogue input , but , randomly if there is a change in the value in some input , this service fail and is necessary start it again. This happen in any input with a voltage , however , in the analogue inputs without voltages, the services always are working.
These are typical messages :
