Mono SDK 1.2: hello_world app randomly waking up
-
I finally got around to upgrading to v1.2 ("monomake version" reports "monomake version 1.2.1").
Unfortunately, it looks like there are still some basic bugs.
I created the usual "hello world" project using "monomake project hello", then cd into "hello", followed by "make" and "make install". This all works fine and I see "Hi, I'm Mono!"
I then unplug the USB cable and power down mono using the button on the side. 10-20 seconds later, mono powers back up again and shows "Hi, I'm Mono!" Pushing the button powers down mono again, and 10-20 seconds later it powers back up.
Plugging the USB cable back in seems to stop this cycle.
Any idea what's going on? Is this a known issue and already resolved?

After building a local copy of mono_framework (following http://developer.openmono.com/en/latest/mono_framework/README.html?highlight=framework), it appears that the issue has been resolved.
It likely could have been fixed by mono_framework commit 4f861348.
I'll update the thread if it turns out that I was mistaken and the problem shows up again.

Yes this issue was indeed fixed by this commit. The fixes will is present in our coming Release 1.3
The reason for the spontaneous wake-ups is false-positive interrupts detected on the display and/or Wifi module interrupt signal. This happened when power was cut from the IC's, and their signal behaved randomly - triggering interrupts that woke Mono.
