Other Parts Discussed in Thread: TMDSEVM6657,
Hi,
I bought the evaluation board for DSP 6657 (TMDSEVM6657) and I started developing some code on it. CCSv8 works with the emulator XDS2xx (PWB 516011 REV.B), which is on top of the DSP eval board connected to it through a 60 pins connector. Next to this one, on the XDS2xx, there is a second 14 pins JTAG connector with the following connection:
I developed a board with Sitara AM5716 and I put a 14 pin JTAG connector in order to use the XDS2xx emulator as in the following schematics:
JTAG_RESETn net goes to Sitara RESETn with a pull-up.
There is a problem when I verify the connection:
[Start]
Execute the command:
%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity
[Result]

-----[Print the reset-command software log-file]-----------------------------
This utility has selected a 560/2xx-class product.
This utility will load the program 'xds2xxu.out'.
The library build date was 'Jan 24 2019'.
The library build time was '13:59:06'.
The library package version is '8.0.903.6'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
An error occurred while hard opening the controller.
-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-183' (0xffffff49).
The title is 'SC_ERR_CTL_CBL_BREAK_FAR'.
The explanation is:
The controller has detected a cable break far-from itself.
The user must connect the cable/pod to the target.
[End]
This is the same message when I don't connect the emulator to the board.
What did I do wrong?
Thanks
Francesco
