Section 13.1: Kinetis Flashloader Chip-Specific Information
PTC10 and PTC11 are not available for I2C0.
PTD4 through PTD7 similarly not available for SPI0.
I imagine the port is correct and the signals are wrong.
Edit: to clarify, I downloaded this revision today from the KV3x page here: KV3x: Kinetis KV3x-100–120 MHz, Advanced 3ph FOC / Sensorless Motor Control MCUs based on ARM® Cortex®-M4
