APM 2.0, MP 1.2.4
Uploaded firmware, connected first time and found no sensor data. Went into CLI. Autotest said that baro is ok, than stopped on gyro. I've reset everything, and since then each connection is failing witt this message:
"Timeout on read - getParamList 3248
Your serial link isn't fast enough"
But this is wrong! I'm able to connect Arducopter 1.0 at least.
