Issue when connecting xds560 JTAG emulator to DM642

Hi,

I face an issue while connecting xds560 PCI JTAG emulator to DM642 EVM.
I've the xds560 emulator inserted in the PCI slot of the PC and installed the driver for it. When I run the diagnostics of the xds560 emulator, all the tests in the diagnostics gets passed without any issue. In the CCS setup, I configured the DM642XDSEMULATOR option and tried opening the CCS. But I get an ERROR mentioning that, "JTAG DEAD CLOCK ERROR" and the DM642 EVM doesnot get connected to the CCS through the emulator.

Can anyone please let me know the procedure to solve this issue.

Thanks in advance,
Karthik. Start a New Thread

If the DM642 EVM uses a 14 pin JTAG connect, this means that TCLK is not
returning on pin 9.
Open a DOS prompt in the 'cc/bin' directory of your CCS installation and
enter the command below [note: If your PCI emulator is not from TI, you may
have to use a different named '.out' file]
xdsprobe -F xds560.out -i
If this fails, you might try manually configuring the JTAG clock in CCS
setup to 2 Mhz. and see if that works.
If it still fails with the same error, probe pin 11 [with emulator cable
connected] to see if a clock is being generated.
