Gryo X sensor fail.

Code: Select all

SYS: Build 31:ba1d111112ad (2013.4) CLEAN
SYS: I am 0x872447275552864966DFF48 and I have 128KB of flash!
IMU: MPU6050 I2C connection [FAIL].
IMU: HMC5883L I2C connection [FAIL].
IMU: MS5611 I2C connection [FAIL].
MPU6050: Self test gyro X [FAIL]. low: 10.0, high: 105.0, measured: 0.0

I have read about the post that talks about the self test and wiki page. I just want to confirm if theres any way to fix the gryo x sensor other than filing a ticket. Or has anyone have this issue? Thanks.

It looks like it can't even communicate with the gyro/acc sensor, the MPU6050. Either the sensor is broken or there is a cracked soldering. If you have access to a hot air station then you could re-solder it by heating it up but else you would have to file a ticket.

Thanks for your reply. Mind if I ask, where do you mean by cracked soldering? soldering done by me on motoers? or the soldering done on the chip board by manifacter? Thanks alot.

It depends, a hard crash could cause it but else it is probably a manufacturing problem. It could also be ESD or something else but soldering the motors would not cause this. This is tested in production though so at some point the MPU6050 sensor has at least worked. This is the first case we see with this kind of issue.

Well. Tomorrow I will be mailing it back to Seed. I have not flew this yet. So it wounldn't be a hard crash. I have soldered the motors first then attached battery, and realized this problem. I guess I should of tested it out first. I guess its manufacturing problem. Thanks again.

Sorry to hear it is broken but Seeed should help you out. PM me if you run into any problem.
