RTOS/TDA2PXEVM: Unable to load from CCS or SD card

Part Number:TDA2PXEVM

Tool/software: TI-RTOS

Hi, 

I am developing on a TDA2PXEM with Radar SDK v.3.04 and CCS v.8.1.0. I have been able to successfully generate the binaries, MLO, and Appimage. However, when I put the EVM in SD mode and insert the SD card with the MLO + Appimage, there is no output from the serial terminal. Similarly, when I put the EVM in debug mode, and load + run the binaries, there is also no output from the serial terminal. I have verified the COM port and baud rate of the serial terminal. Why might the EVM not be booting up correctly? 

Thanks,

Richard
