TMS320F28069: Unable to read data from the controller

Part Number: TMS320F28069


Hi,

I have made F28069 custom design for my application. I am able to program the controller with JTAG XDS100V2(with matlab simulink coder). 

But when I have tried two model approach I was unable to read data from the controller transmitting to the host PC.

But the same thing I was able to implement with TMS320f28069 launchpad stand alone.

As Tx and Rx modules are not connected to JTAG, how the communication is getting established? is it communicating with JTAG pins itself? I have configured sci tool box with Module A... 

So what will be the possible reason for this? Am I Missing any specific pin pull up on pull down in micro controller schematic(Schematic is attached)?
