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?

    Hi,

            The JTAG port signals need to be correct for establishing the target connection with VDSP++. There are case where the target connection error will occur even if CLKIN, RESET and power supply to the chip are not connected properly. It is better to make sure that all the DSP signals are connected properly.

    Regarding the reflow profile the JEDEC standard you have been using is the one recommended for this device. We may need to understand why this fails for your case. Please make sure that your reflow temperature and the times are calibrated correctly. We may continue further discussion on the reflow profile under our private support system.
