CCS/LAUNCHCC3220MODASF: CS_DAP Error 1170

Part Number: LAUNCHCC3220MODASF
Other Parts Discussed in Thread: UNIFLASH

Tool/software: Code Composer Studio

Hello all,

I am using the CC3220MODASF launchpad in combination with CCS Version: 9.0.1.00004.

My problem is: I can't debug anymore.
All debug sessions results in "CS_DAP: Error connecting to the target: (Error -1170 @ 0x0)".


The way described in the forum, message "CortexR4: Error connecting to the target: (error -1170 @ 0x0) Unable to access the DAP" doesn't help.
It describes a way using the targetConfigs from inside of CCS.
Factory reset also not helps (I never flashed any image to this board).

One of the last things I did, was to try to flash some User Files.

UniFlash still connects to the board. After pressing "connect" it get the following information.
The Image Mode in the section "General -> Settings" is set to "Production".

I assume the device is set into production mode. How can I set it back to development mode?

Many thanks in advance,
Roman Jordan
