I tried routing I2C to P3.0 and P3.1, both valid pins for SCB1. It compiled ok and uses SCB1 which has those pins, but no output is appearing at those pins. If I let Creator do the pin assignment it automatically uses SCB0 and pins 4.0 and 4.1. The output appears fine on those pins. I think this is a bug.

If you are really sure about this issue you should create a MyCase and inform Cypress.

Look into the schematics of your Pioneer board: P4_0&1 are equipped already with the necessary pull-ups while P3 isn't.

I was using external pullups for the test, using master mode and auto routines.
