TMDSIDK572: How to take the C66x DSP out of reset with Linux running on Cortex-A15 core

Hello!

I use the evaluation board "TMDSIDK572" (so with the SoC "TI AM5728").

I'm using CCS v12.2.0.00009 with installed "Sitara Device Support v1.6.3.

I have now created a CCS Project for C66 DSP.
In the project directory there is also a target configuration "IDK_AM572X.ccxml".
I have checked the connection to the target.

Now I start a debug session with the "1 Code Composer Debug Session".
After some steps it stops with the following error message:
C66xx_DSP1: Error connecting to the target: Device is held in resest. Take teh device out of reset, and retry the operation. (Emulation package 9.10.0.00080)

I have started the "TMDSIDK572" with Linux from the SD card.
I realize that this does not take the DSP core out of the reset state.

I have read the documentation "6.2.6. Taking the C66x Out Of Reset with Linux Running on the ARM A15":
https://software-dl.ti.com/processor-sdk-linux/esd/AM57X/08_02_01_00/exports/docs/linux/How_to_Guides/Targe/Taking_the_C66x_Out_Of_Reset_with_Linux_Running_on_the_ARM_A15.html

I have also read the documentation on "TMDXIDK5728 Hardware Setup":
https://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_how_to_guides.html#tmdxidk5728-hardware-setup

However, I can't get any further with it, as I can't follow the steps described.
I can't find the menu item "Lunch selected configuration".

What exactly does "Launch Target configuration" mean?

How do I get the DSP core out of reset without disturbing the running Linux system?
