Hi Diego,
Adafruit tech support was able to resolve the error, but the other Adafruit libraries are exactly as you mentioned.
Intel® Galileo Board TFT LCD Connectivity: White paper
Why does the Intel Whitepaper reference the Adafruit shield in the White paper above ?
Here is the Adafruit support link:Adafruit customer service forums • View topic - Galileo and LCD TFT 2.8" V2 Compatibility
Thanks,
