I'm quite experienced with single PCB linux based systems, but I'm really beginner on Arduino. And even though Arduino is quite popular, I have significant trouble to find basic information for setup. Meanwhile I can compile and upload, I can interface with Processing on my Mac, but every time I do a power cycle, the Arduino seems to have lost the uploaded file. To my understanding it should have a flash, does the IDE only load the code into the RAM? Is there any possibility that the Arduino executes my code on power on? I'm using a MKR1000. I found this issue in the troubleshooting guide, but I don't understand. I suggests that the cause may be serial data coming in. But I just connect the board to a USB power supply. Same if I connect it to the laptop.
Thanks in advance !
