TMS320F28069: How to run TMDSCNCD28069ISO controlCARD from Flash

Part Number: TMS320F28069
Other Parts Discussed in Thread: C2000WARE, TMDSCNCD28069ISO

We are having trouble running the TMDSCNCD28069ISO controlCARD from Flash. As a starting point, we are using the 'flash_f28069' header file example from here: C:\TI\c2000\C2000Ware_1_00_06_00\device_support\f2806x\examples\c28\flash_f28069

We have programmed this on TMDSCNCD28069ISO and confirmed that GPIO34 pin toggles while connected to CCS. We have also confirmed that SW1 bits 1 and 2 are both on, to pull the boot pins high. When we disconnect CCS and cycle power, the example doesn't run as seen by observing no toggles on GPIO34.

We then connect CCS without resetting and we can see the device is executing from Flash at address 0x3FF75C.

Are we missing anything else needed to run from Flash on this board?
