TMS320F280049C: Error connecting to the target: (Error -2131 @ 0x0)

Part Number: TMS320F280049C

Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 8.2.0.00004)

I get the above error when I try to load code into the the TMS320F280049CPZS control card which is placed on the controlcard docking station. 

And the D1 LED on the control card is flickering instead of a solid ON. 

Is there a hardware problem? 

I have another control card which I am able to power and debug without any problem.
