Hello there, in the features page, it is said that: "Connection to the SAM3X from external computer Arduino compatible board embedded on UDOO can be also programmed from an external computer through the mini USB serial, like you are used to do with standard Arduino board. Like any other Arduino boards, serial data are also available at pin 0 and pin 1 (RX0/TX0). The switch is controlled via software by the iMX6 or by a physical jumper (J18). " could anybody please elaborate on what kind of "software" in that paragraph or any examples? Thank you!
You might be referring to this? "To program the Atmel SAM3x8E from an external Host PC, it is possible to use the standard Arduino IDE. 4.1. Download Arduino IDE Download the Arduino IDE for free at the official website: http://arduino.cc/en/Main/Software Download the version for the O.S. used (must be 1.5.2 or newer release)" via http://udoo.org/download/files/Document ... 0_2013.pdf
Wait a second, there's a misunderstanding going on here: "The switch is controlled via software by the iMX6 or by a physical jumper (J18)." This refers to an old version of UDOO's documentation which is still on UDOO's website, we're going to update it asap. No more software control involved in order to protect the iMX6 CPU (where software stands for the iMX6 being able to "move" the switch as if it were a GPIO). At the moment the only way to enable the Serial connection to the SAM3X from an external computer, is through the physical jumper in J18. When the jumper is not plugged in, the micro USB is connected to the Programming Port of the SAM3X, when the jumper is plugged in, the micro USB is connected to the iMX6's serial. Hope this help!
