[Paparazzi-devel] Changes in module imu_mpu6000_hmc5883.xml

Back a couple of years Felix kindly helped me getting data from the onboard baro on Aspirin IMU 2.1 r1. To achieve this the subsystem mpu6000_hmc5883 was created.

Everything has worked fine up to, and including v5.8. Now when switching to v5.10 I couldn't get data from the IMU anymore. I'm on Ubuntu 16.04 LTS.

After scratching my head a bit I changed SPI_SLAVE0 to SPI_SLAVE2 in line 44 of conf/modules/imu_mpu6000_hmc5883.xml. Then I got data from the IMU again.

Note that I have removed two pullups and added two jumpers on the Aspirin to connect baro and mag directly to I2C2 on Lisa/M.

I am not sure if others use this subsystem. If this is the correct way to fix it, could it be made permanent in v5.10 onwards?
