TMS320F280039C: X1 clock not saturating on custom PCB

Hello Ti experts, 

I built a PCB featuring C2000's F280039C chip. The schematic mostly follows the LAUNCHXL-F280039C design except for the clocking, where I decided to only use the internal oscillator.

I left X1(GPIO19) and X2(GPIO18) floating on the PCB. Is this a mistake?

After loading a small test program, I get stuck at this line in ccs:

Here are some more details about my application:

-I am using XDS110 Debug probe

-Both 3.3V and 1.2V rails seem to work fine.

-The JTAG integrity test is successful

-The nRESET signal interrupts the debug session correctly when pulled low

-The emu (all 4) signals on the probe are left floating

Finally, is this mistake fixable by clever soldering?
