CCS/66AK2E05: xds560v2 pro trace not connected on EVMK2EX development board

Tool/software: Code Composer Studio

Hi,

I am using xds560v2 pro trace jtag with ccs8 on linux host machine using usb cable.

jtag is connected to an EVM2KE evaluation board.

EVM board configuration switches are all set for CCS booting.

My "General setup" on CCS is the following:

Connection: Spectrum Digital XDSPRO USB Emulator

Board or Device:  66AK2E05

However when trying to test connection I get following error:

-----[Print the board config pathname(s)]------------------------------------

/home/gkor/.ti/ti/0/0/BrdDat/testBoard.dat

-----[Print the reset-command software log-file]-----------------------------

This utility has selected a 560/2xx-class product.
This utility will load the program 'sd560v2u.out'.
E_RPCENV_IO_ERROR(-6) No connection: DTC_IO_Open::dtc_conf
Download failed for file /home/gkor/bin/ti/ccsv8/ccs_base/common/uscif/./././././xds560v2.out

An error occurred while soft 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 '-250' (0xffffff06).
The title is 'SC_ERR_ECOM_EMUNAME'.

The explanation is:
An attempt to access the debug probe via USCIF ECOM has failed.

[End: Spectrum Digital XDSPRO USB Emulator_0]

this error does not happen on windows only on linux host machine (which is CentOS 7)

Thank you very much!
