NunchukRF flashing problems...

Okay, now i have built the whole PCB and soldered the Z and C-buttons also.

When i flash it, the all LEDs lit. When i pull it out of the USB and put back, only the blue is on. That seems normal so far.
But when i put it on battery or USB, no matter what i do, i can't get any LEDs on except the blue when on USB. Pressing C and/or Z does nothing.

I checked all with continuity test, and everything seems to be connected. Now it seems to be software problem. But where to look at?
I have all address resistors populated, whick means address 15, according to some other forum thread.

Is there any official guide for this? I can't seem to find anything, not even how the address resistors go.

EDIT: Strange. When i connect it to computer, start virtualbox(Windows 7), connect the device, then the leds start to work. Blue activates briefly when i hit any button or joystick, and other two blink randomly.

So now when i connected the battery, then connected it to Windows7, and disconnected from computer, it seems that it is functioning; no light -> press Z&C -> red lights, then goes off.
That seems so far to be best i can get out of it. It still can't connect to VESC though. As i understand, it should stay red, and it would be good to go.
But it should'nt work like that i need to connect it to Windows first..

I did the settings like in this thread: viewtopic.php?f=15&t=75

There is too much unsure variables. Could anyone list the facts that what must be how to things to work?

Okay... Strange...

I Googled into a german site: http://www.elektro-skateboard.de/forum/ ... f-5092.php

I tried that firmware that was there, and suddenly it worked! Although i needed to "activate" the device by plugging it into Windows7. What is the thing with that??

It was this command: stm32flash /dev/ttyUSB0 -i -rts,dtr,-dtr:rts,dtr,-dtr -b 1000000 -w ws2812_rf.hex -v -g 0x0
I tried to upload the official code with same command, but didn't change anything.

I have had problems with the nunchuk. It dies randomly, and usually awakens when i connect it to Windows.
Now when i changed the battery and i got short on 3V3 regulator VCC and GND pins, the regulator got broken. I replaced the regulator. But now when i try to connect, it just flashes the green led, and doesn't connect.
Firmware upload still works.
And when i connect to Windows, the red LED flashes, and when i press "connect" on BLDC Tool, the red LED stays as long as it tries to connect.

Is there anywhere any info what all LED status mean?
I also saw some voltage-related info with LEDs on the source code, but i know almost nothing about coding...

In the meantime, i might as well make another nunchuk as spare, and to see how it behaves..

EDIT: Now i made a new one. It works exactly like the previous. But now i noticed that i don't need the Windows afterall. All the nunchuk needs to activate is something that tries to talk to it. BLDC Tool connection attempt was enough to activate it.

But i have still the problem. The default firmware is not able to connect to VESC, while this mysterious germany-edition can.
I need to ride tomorrow a test ride and see how this new nunchuk performs.
