Unable to flash using Keil Ulink2 LM3S5R31

Hello,
I am having had time trying to communicate to my new board with stellaris LM3S5R31 using Ulink2. whenever I try, I get a message that "Erro: Flash Download Failed - Target DLL has bean cancelled". I get this error both through keil ulink2 and TI's ICDI board.
However, if i use the LM Flash programmer - Build 1154 , I can program and verify the contents and the MCU works perfectly fine :)

Can anyone suggest me what needs to be done the keil side to get this working. In fact I upgraded to 4.2 and also change the time-out to 500 msec but nothing seems to be working!!

One more thing, I can not communicate even when I select Do not erase and do not program, ie there is nothing to be done, but still get this error when I press the download button!

Any help in this regard to much appreciated.

Thanks in advance
Rajan

Sounds like you have locked-out the JTAG on your board.

Check the TI forum for the solution...
