LS1046ARDB: Failed to start flash programming services using Code warrior TAP

[jerin_mathew]

Following error is obtained while trying to initiate flash programming services on LS1046ARDB using code warrior TAP. We tried setting the RESET_REQ_B(SW4[8]) to OFF as suggested in the logs, but it didnt resolve the issu.   Attaching the cw_flash.py for reference.

RCW error encountered. In order to diagnose the error temporarily change the board configuration switches to ignore the assertion of the RESET_REQ_B signal. Please refer to board reference manual in order to locate the appropriate switch that controls this behavior.

There is no valid RCW on the target board.

Please configure switch setting SW5[1-8] SW4[1] as 0100_1111_1 to configure the target board as hard-coded RCW. 

After QSPI flash programming, please configure switch SW5[1-8] SW4[1] as 0010_0010_0 to configure the RCW source as QSPI flash on the target board.

If further assistance is needed, please feel free to let me know.

In addition, please refer to the attached cwflash.py script.
