Rebuilt using the Altera EDS15.0 toolchain:

  arm-altera-eabi-gcc --version
  arm-altera-eabi-gcc (Sourcery CodeBench Lite 2014.11-13) 4.9.1

Get same result ... mostly failing calibration, non-working USB....

Does this work for anybody else?
Is it in anyone's experience that these (cheaper) Terasic
eval boards are generally out of spec?

Is there a way to relax the calibration parameters? the USB parameters?

Would it help if I posted debug output?


Thanks,
