Excellent.  I'm glad that you're able to reprogram the chip.

That's not the right speed for the system, but it is 1/8th the
correct speed.  That indicates to me that it is using the internal
RC oscillator at 1 MHz rather than the external crystal at 8 MHz.
You need to set the fuse bits for CLKSEL=1011 (fast rising, external
crystal oscillator) rather than the default internal RC oscillator.

This means that there is no magnetometer hooked up.  You can
undef CONFIG_PNI in mainloop.c to stop it from trying to read one.

This typically indicates that there is no IMU plugged into the
J1 header.  The readings when the ADC is free floating just sort
of randomly move.  Is your IMU board plugged into the controller?
