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.
