CCS/F28M35M52C: XDS200 cannot connect to the target processor board

Part Number: F28M35M52C

Tool/software: Code Composer Studio


  I have a customized processor board and a XDS200 emulator.  My software is demonstrated operational by flash programmed to the TI evaluation card by using the built-in emulator.  Now I tried to flash program the my customized processor board by a XDS200.   When I ran Launch Selected Configuration under View-> Target Configuration, I got Disconnected message as, 

Texas Instruments XDS2xx USB Debug Probe_0/Cortex_M3_0 (Disconnected: Unknown)

Texas Instruments XDS2xx USB Debug Probe_0/C28xx_0 (Disconnected: Unknown)

At Console, error message as,

Cortex_M3_0: Error connecting to the target: (Error -1266 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package

C28xx_0: 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

 In hardware, the pin 2 of JTAG connects a pull down resistor to GND.  Any comment and suggestion?
