Flash problem with MC56F8355

I install the Flash Programmer, try to write in a S-record file to DSP56F8355 with CodeWarrior USB TAP.

But it always failed, says that the device is not powered up or there is another error communication.

I update the latest CCS driver, and check all other settings in Flash Programmer, should be alright.

Actually 2 years ago, i did the same thing and it was successful, but this time with nothing change, just another DSP56F8355.

There is a adaptor with a 47k Ohm resist on PIN 12 and 13, to connect the JTAG pin with the USB TAP.

When the adaptor is in right direction, it shows the error i mentioned above.

When i reverse the adaptor, the flashing success, only erase the configuration without write in new configuration.

Can someone help? It really bothers me too much!!
