CCS/TMS320F28335: JTAG programming error

Part Number:TMS320F28335

Tool/software: Code Composer Studio

Hi, i am working in my TMS320F28335 test board. During debugging CCS shows

"C28xx: Error connecting to the target: (Error -1155 @ 0x0) Device may be operating in low-power mode. The debugger has forced the device to wake up. Choose 'OK' to attempt to complete the debug connection. (Emulation package 8.0.903.6)" 

After observing i found that I mistakenly left XRSn pin unconnected. So i tried to made XRS pin manually high during debugging, still i get the same error. Next step i manually reset the device by pulling the VDD low, Now CCS debugs but program doesnot works. I am new to DSC's and CCS, so i can't able find my mistake. Could anyone notice my mistake please give any solution. Hereby i attached my program to blink LED and the reported CCS screen.

And please let me know what is the exact procedure and steps to be followed to debug the DSC for first time in CCS
