Flash programming using Code warrior with CMSIS-DAP Failing.

I am trying to update kernel image using CMSIS-DAP debugger on FRDM-LS1012A board But getting below errors:

Follow the instruction given in "flash programmer" section of "CodeWarrior Development Studio for QorIQ LS series for ARM v8 ISA" documents to do flash programming.

Steps Followed:To start the flash programmer, perform the following steps:

Update the cwflash.py with 'PROBE_CONNECTION = "cmsisdap:20000203C19E4E733C62918B" ', 'SOC_NAME = "LS1012A" '.Rest are as it is.

Open a terminal and switch to the following location:
```
{CW Install Dir}\CW_ARMv8\ARMv8\gdb\bin 
```
Start GDB from this location:
- Windows: Run aarch64-fsl-gdb.exe
- Linux: Run ./aarch64-fsl-gdb

Execute cwflash.py script.

source ../../gdb_extensions/flash/cwflash.py

Test your board using CMSIS-DAP as debugger connection.

Is there connection to the FRDM-LS1012A board under CodeWarrior using CMSIS-DAP?

See attached screenshots.

Configure Target Connection and Activate.

Have a great day,
