I have been running an Arduino sketch found /thread/53869 here that I uploaded to the board via Arduino IDE. I modified the script to print sensor readings to a file saved on Galileo. The sketch runs in parallel to a Python script that reads the file. The sketch and the script were working properly together until I set the Python script to run on startup rather than on demand. To run the Python script on startup, I followed the instructions http://www.pietervanos.net/knowledge/start-python-script-from-init-d/ here.
Once I had the Python script run on startup, I noticed the file that Arduino should be writing to was no longer being updated. I opened my Arduino IDE to see if re-uploading the sketch would solve anything, and this is what I saw:
Additionally, I tried to see if I could run the sketch on demand following the discussion /message/482884# 482884 here.
I am using the Yocto 3.8.7, iot-devkit version 3.5 image.
Thank you for contacting us.
This is an interesting issue. Having a Python script running at startup should not be an issue if everything was working fine before.
