By mistake when I wanted to connect the wire GND to the servomotor, I touched the end of the wire 5V and there my UDOO restarted. Now my UDOO no longer recognizes the Arduino part.
When a person develop the code for Arduino 101 (Intel Curie processor), such as under the Arduino IDE, it will recognize the target system (Intel Curie) is a processor with embedded USB engine (which emulate the USB-serial device, known as CDC-ACM device). Such that the compile binary will not only include the (1) user code and (2) Arduino own house-keeping code, but also the (3) serial USB code to configure Intel Curie's USB engine to behave as a USB-serial device. The above the ordinary way, if under Arduino IDE, It's automagic. Not sure what you did on your compilation/linker process, but it will have to be under the same logic (if not using the Arduino IDE method.)
ttyACM0 has completely disappeared in both the /dev directory and in the arduino IDE I reinstalled 5 times I spent my time walking the net in order to find a solution without any results
When doing ls /tty* several times in the /dev directory, I notice that ttyACM0 appears briefly. It's incomprehensible
It's good, I put the thread between the RST pin and the GRN pin. It has reset. For now everything is working well. And before I followed this http://bartruffle.blogspot.com/2013/09/dfu-programming-atmega16u2-on-arduino.html
