TS101 Programming Issue

We have TS101 based DSP board. EMU, TCK, TDI & TMS signals are pulled up by 4.75K resistor to 3.3V DSP line.

When trying to program the DSP with HPUSB-ICE emulator, I got error " An EMUIR scan was attempted ,but the dsp is not ready to accept instruction via JTAG ". In Visual DSP configurator, with the "Test" option JTAG scan is passing for all the parameters are passing. What could be problem in programming?
