Part Number: TMS320F28P550SJ
Tool/software:
Hello,
I'm testing a board with the TMS320F28P550SJ microcontroller but I am unable to connect via JTAG.
Power supplies are good and the microcontroller exits from reset state.
I tried to follow all the suggestions found on forum and TI's wiki but without success, currently the boot mode is set to "SCI/ wait boot mode". If I try to connect to the board I get this error (-1135):
I tried to lower the JTAG clock down to 100kHz and executing the "Test Connection" from Code Composer ccxml editor the result is good. Output of test is attached in the following file.

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the XDS110 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for XDS110 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).

How can I further investigate the issue?
Thanks
