[Paparazzi-devel] i2c silent again

[SilaS]

Hi David,

I am again in trouble. I want to replace my powering from 3S to 4S 
because my neutral-hower-throttle was around 80% of throttle.

For to do it: I removed the power from main power distribution board and 
made a connector for balancer port of the same battery as feed the power 
board. On balancer I connected only the first 3 cell and therefore I 
hope that can watch the consumption while i got my atto sensor.
I powered first the AP over balancer and a few minutes later the main 
connectors. The AP started perfect, the I2C ESC-s - what I got also from 
You - started as regular, but at the end all show red LED on, so 
indocate no signal on I2C0 bus!!!!
So I can not start the motors!!!!

A few minutes later I made everything back to 3S config. But the problem 
is the same! What can happen? How can I check the I2C communiction of AP?
