now I tried a lot to and it still doesn't work. I'm running the preinstalled OpenIMU "IMU" application (and also tried it with installing the online available bin).
I removed the Jumpers from P1 to enable SPI mode but the IMU simply doesn't answer.
Also I tried different registers (hw version, software version, etc.) and SPI frequencies (from 100kHz to 1MHz) but there's no reply anyway.
When i fit the jumpers the online-webserver connection works fine.
Do you have any idea what could be wrong here?
