Yes it is possible to run multiple sketches through the Linux side, but is not recommended because they use the same resources and they don’t work properly. If you want to run several programs at the same time I’d suggest you to use node.js, Python or C programs with the Arduino sketches. Regarding your issue, have you tried re-flashing your board to double check that is not a software issue of the image you are using?
I re-flashed the board at least 3 times now, but all MAY come to BSOD.
And if I just connect microUSB(the real COM) to PC, using putty got error, say that unable to open port. And if using the virtual COM by putty, it can open.
I'll flash again and see what happens.
but what happened to "systemd-journal", it made so many messages.
I re-flashed in Monday, and without installing Wyliodrin, and use the hex nuts, so far so good. No BSOD yet. Maybe Wyliodrin's problem?
And my friend suggests I forgot "Hand tighten the hex nuts onto the two screws that protrude through the Intel® Edison board." before. This might be confuse, I don't think it would lead to BSOD if not use the hex nuts.
I'm currently using C/C++ programming, and found out that I cannot establish HTTPS connection, even wget reports :

If you get the error again it might be due to a windows issue, if this is the case try the following:
- Control Panel
- Hardware and Sound
- Power Options
- Choose what the power buttons do
- Change settings that are currently unavailable
- Uncheck “Turn on Fast startup”
- Save changes
Let us know if this happens again.
