SK-AM64: Error connecting to the target from CCS 10.3.1

Part Number: SK-AM64

After following the steps as described in https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/latest/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html to configure EVM (adapting to SK boot-strap switches), R5&M4 core get properly initialized on powerup-boot with OSPI boot-mode as per the Terminal output shown below:

CCS still did not connect to R5 (or any) cores in NO_BOOT or OSPI boot mode with the same error.

Tried the related posting with no success.

But, was able to connect to R5/M4 cores after disconnecting and connecting the JTAG USB connector back. This needs to be done on every power-cycle.

Is this a known issue?
