TMS320F280049C: Error -2131

Part Number: TMS320F280049C


Tool/software:

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).

Hello, I have been trying to connect the XDS110 debugger to TMS320F280049C MCU on PCB. I am using the TI20-14pin converter and have connected all necessary pins. How would I go about resolving this error & how do I enable the internal pull up resistors on TDO and TDI. Thanks.
