Which board are you using?
I think that for some of the hardware, PB2 is used as a chip select for SPI peripherals.
Is there a PBFR (Port B Function Register) that configures it for something other than a standard digital output? Does the schematic for the core module show it connected to anything? Does the core module documentation mention anything special about PB2 on the pinout diagram?
