CODECOMPOSER: XDS560v2 connection error in custom board

Other Parts Discussed in Thread: DRA821U-Q1, DRA821

Dear Champs,

My customer faced JTAG connection error when they tried to connect XDS560v2 Blackhawk USB to their custom board and test connection in CCS as below.

The strange thing is there is error code occurred as below.

They tried to use lower JTAG clock at 100KHZ as below, but still same.

When they tried to test JTAG connection in command window with below command,

c:\ti\ccs1210\ccs\ccs_base\common\uscif\dbgjtag.exe -X emulator,driver=bh560v2u -S givendata,repeat=0

They got below error code.

So, they checked the voltage in VTRef pin of JTAG, and found 3.3V output in VTRef pin, and now I have no idea what can I suggest to them further.

Could you please let me know your idea what should be checked further to debug this JTAG connection fail issue?

DRA821U-Q1 device was used in my customer's board.

Thanks and Best Regards,

SI.

Hello.

Regarding message:

The controller does not use a programmable FPGA.

You can disregard that message. It is not relevant. This message always occurs on all the production XDS560v2 debug probes.

I am surprised that the "Test Connection" function did not provide more details though.

This is more helpful.

Sounds like they checked all the correct things.

Is this a custom board or some EVM from TI (or other related distributor)?

Thanks

Have they ever been able to connect to this custom board in the past with any JTAG debug probe?

Hi Ki,

Actually there is no issue to connect JTAG on their board which DRA821 HS device(HSFS) was assembled, but this issue occurred with DRA821 GP device on same board. We are trying to connect using XDS110 now, but it would be helpful if you have any idea to check further.

Thanks and Best Regards,

SI.

I'm not sure I quite understand... on the same exact board you are able to swap our DRA821 HS for DRA821 GP?

Yes. your understanding is correct.

When they tried to connect using XDS110, they faced same connection fail error.

Thanks for clarification. So you have one board where you swapped out a DRA821 HS for DRA821 GP. When the DRA821 HS was there, everything worked. When the DRA821 GP was swapped in, things started to fail. This appears to be some hardware issue and not a tools specific issue.

I will bring this thread to the attention of the device experts who can assist further.

Thanks
