I've not been able to find the function for these anywhere..... There are 2 buttons: SW2 on the front of the board and SW1 on top, both located near the FRONT_PANEL and IR Sensor - Top Right in this image:
Related to those buttons is the front panel connector. It has 9 pins where pins 5 & 7 are reset and 6 & 8 are for a power switch. I've been using the buttons since I have no case for this yet.
The SW1 (black) button is the Arduino Master Reset; the front SW2 (grey) button is power on/off. If you have the standard UDOO X86 acrylic case there is a hole above SW1 so you can easily Reset/Run Arduino Scripts. See Ref: http://www.udoo.org/docs-x86/Hardware_Reference/Overview.html
Ah, so it is RST only for the Arduino, and not the Intel, correct? The power button, I'll have to play with.
I tried pressing SW1 from the BIOS screen, within Ubuntu, in apps, and it has no effect. So it looks like it is used only to Reset/Run the Arduino side of the board.
Search for RSTBTN# and PWRBTN# on the schematic. These buttons route to both the Braswell SoC and the STM32F. Page 29 of the user manual describes it as well.
Here it is described as "Arduino master reset". I didn't try by myself so i don't know what it actually resets.
I read what @fabio978 sent and tried it. I was successfully running one of the IMU programs then I hit the master reset and the IMU data stopped. Sounds good but I'm not sure what actually happens to the STM32F. So, I restarted the Arduino IDE and tried to upload the sketch. It was having problems (see the attached message) and the IDE asked me to hit the master reset. When I did, I saw COM3 removed and added back to the Windows device manager list. Then the sketch was successfully uploaded.
Where can I find the layout of the front panel header pins (mainly which pins equal what connections.)
