Debugger launch from command line: connection issue

Hi

I want to launch the debugger from the dos command line:

I first follow the steps as described in the debugger user guide, chapter 8.

I entered something like that

debugger --cdb-root I:\try_env\flow\imx8qm\configdb_extension --cdb-entry "NXP::IMX8QM_SCU::Bare Metal Debug::Bare Metal Debug
::Cortex-M4::DSTREAM" --cdb-entry-param "Connection=TCP:10.81.17.131"

I had the error message:

ERROR(TAD290-DTS77-DTS77-NAL57):
! Failed to connect to platform I:\try_env\flow\imx8qm\configdb_extension\Boards
\NXP\IMX8QM_SCU\IMX8DV_SCU.rcf
! Unable to connect to
! Unable to connect to
! Unsupported connection type

So I put the config db in the ds5 install dir (under sw\debugger\configdb) to see if issue comes from the extra DB.

But I got same error

So few questions:

1)The -cdb-entry string is not easy to guess , maybe error come from here: Sounds we have to guess the value

2) the TCP address is ok, I am able to connect from the DS5 GUI, but shouls I use address instead of conenction? in that case I need to use a Port? what is the default value?

3) the browse option return nothing

4) Using others configuration leads to same issue.

I am using a beta version of DS5 (v5.25.99) under windows 7.

Any help would be appreciated.

thanks
