RCW source configured (cfg_rcw_src) as hard coded RCW and the new RCW value are loaded over code warrior. This was working fine and there is no issue during connect operation of code warrior afterward i programmed the RCW in NOR flash and changed cfg_rcw_src as NOR Flash. This is the sequence followed during board bring condition.


I erased RCW data from NOR flash and try to connect with code warrior using cfg_rcw_src source as NOR Flash. it was connected properly. without change the cfg_rcw_src as hard coded RCW.


In other case NAND flash also contains the RCW source but cfg_rcw_src source configured as NOR flash.


1) Whether hard coded RCW setting is required even RCW data is not available on NOR flash?


2) Whether it is possible to fetch the RCW data from NAND, if the RCW selected source does not contain any RCW?
