When I connect I get the following along with flashing red light x5:

ng!
SYS: Build 89:54fa51cb6ea0 (2014.01.0) CLEAN
SYS: I am 0x870240294949775066h!
IMU: MPU6050 I2C connection [OK].
IMU: HMC5883 I2C connection [OK].
IMU: MS5611 I2C connection [OK].
MPU6050: Self test [OK].
HMC5883L: Self test pos Z [FAIL]. low: 380, high: 570, measured: 1

I assume the HMC5883L is not working? It was doing this even before I assembled the motors. I tried to update firmware several times and that did not seem to help.

Help!

It might be because of a strong magnet field nearby which could cause saturation, but I would say a bad sensor. You have the option to contact Seeedstudio support to get a replacement or if you are eager I can compile a firmware with the magnetometer tests disabled. Only some special FW make use of the magnetometer.

I have attached the 2014.01.0 firmware with the mag tests disabled if you would like to test.

Cool thanks I'll try it tonight. Had anyone been able to get ahold of anyone at SeedStudio for a return? I've tried to e-mail and call them the past few days but I haven't received any response. I ordered two more units, but I'd like to exchange this one that I have. Any ideas?

Thanks,

Johnathan

Our understanding is that their support should be pretty good but we have not really used it so I can't really tell.

I know this is an old post, but I tried the fix in the post, but it looks like it is still running the HMC5883L test and it is still failing, though my red flasing light is now 2 Hz. Console still shows HMC5883L: Self test pos X [FAIL]. low 408, high: 612, measured: 0
