Hello,
I just finished wiring up the JTAG and power circuits for the F280021, and I want to make sure everything is correct.
Both the VDDIO and VDDA pins need a 3.3V supply, right?
Also, is that pull-up tied to VDDIO done correctly?

Please consult the Datasheet for recommendations, its kept up-to-date with all the latest recommended connections for each pin.https://www.ti.com/lit/gpn/tms320f280021

Yes both VDDIO and VDDA should be connected to 3.3V. Please note that they both have decoupling capacitor requirements mentinoed in the DS.

Are you talking about the TMS pin? This needs a pull-up resistor to 3.3V, it doesn't specifically have to be VDDIO. Looking at your net names VCC_3V3 connects to VDDIO and then VDDIO connects to that pull-up so you're OK.
Ps,
