Problem when connect XDS510 USB with DM6446 KIT

We've just bought : DM6446 Digital Video Evaluation Module. I installed this KIT with Linux OS (Ubuntu), CCSv5 and XDS510 USB JTAG (14 pins). I connected XDS510 USB with Davinci KIT through MPS430 JTAG (14 pins) and did follow TechNote_11.pdf.

The first step to test connection between PC and emulator (through USB port) is OK

But the second step to verify the connection between emulator and the target I got error:

.../emulation/drivers$./sdjtag -p 0x510 -X scantest

SpectrumDigital USB Jtag Utility

** Emulator scan test

error -- XDS510USB test fail

error -- check power to your emulator/eZdsp

error -- then check your port address

 

When I searched on the internet, I found some information:

- Features not available on Linux: MSP430 (http://processors.wiki.ti.com/index.php/Linux_Host_Support)

- The TMDSADP1420 adapter is used for connecting TI and 3rd party XDS510 and XDS560- class emulators with a 14 pin native connector to the TMDSEVM6446 or customer boards with a compact (CTI) 20-pin header (http://focus.ti.com/docs/toolsw/folders/print/tmdsevm6446.html)

- Information about TMDSADP1420 adapter: http://focus.ti.com/docs/toolsw/folders/print/tmdsadp.html

 

From these information, I think I have to use TMDSADP1420 to connect XDS510 USB with DM6446 KIT through Emulation Header (20 pins) (not MPS430 JTAG) or buy new XDS510 (20 pins). Is that right?

    I am not quite sure if I understand how your connection is setup. The XDS510USB (not plus) emulator requires the TMDSADP1420 adapter and must be connected directly to the J1 connector (marked as Emulator Header). The MSP430 JTAG header (J2) can only be used with a MSP430 emulator and does not perform debugging on the DM6446 device.

    This message indicates the target has no power, which is consistent with the different JTAG pinouts for the MSP430 and the DM6446 emulation interfaces.

    Yes, you are correct.

    Hope this helps,
