I’ve determined that having the eval board isn’t going to help. The problem seems to lay in how the mosfets are being driven. The settings for the eval board most likely won’t work with my board.
After making some changes to the parameters, I am now getting an undervoltage lockout. This implies that VCC is being shorted to GND. I suspect that the low side mosfets are turning back on before the high side ones are fully off.
