Hello Jeremy,
I have reviewed the schematic and have the following comments:

Hi Jeremy,
Is GPO2 need pull up 3.3V ?
Yes. See the description in the datasheet.
For the recommendation of the series resistor between the OSC1 pin and the crystal, I was not talking about a 1M resistor between OSC1 and OSC2 pins. The TCAN4550-Q1 already has an internal 500k resistor between OSC1 and OSC2. Instead I was talking about a series resistor located directly between the OSC1 pin and the load cap and crystal. The purpose of this resistor is to help reduce the amount of current flowing through the crystal and reduce the Drive Level or power dissipation if necessary.
Regards,
Jonathan
