           I have been imported an example project in LPCXPresso with the processor LPC3250. I have connected the LPC-Link to our own board which is having JTag connections like TDI,TMS and TRST are pulled up with 10k, And TCK and RTCK are pulled down with 10k.

           When i tried to debug the project i got the below errors,

LPCXpresso Debug Driver v7.8 (May 28 2015 02:56:45 - crt_emu_a9_nxp build 181)
