Hi, I tried to connect the two processors following these steps because I need to use the camera module from Arduino (http://udoo.org/download/files/Documents/UDOO_Starting_Manual_beta0.4_11_28_2013.pdf Chap: 3.2 & 3.3). First I started with something simple: I removed the jumper J18, and uploaded this sketch: void setup() { Serial.begin(115200); } void loop() { Serial.println("hello"); delay(100); } I guess this should be send over serial and can be accessible in terminal. Then I tried the following commands in terminal to view what I sent from Arduino: stty -F /dev/ttymxc3 cs8 115200 echo message > /dev/ttymxc3 cat /dev/ttymxc3 But this actually doesn't show anything, I can't view that "hello" from terminal. Is it ok? How should I fix this and how connect the two processors then?
