So I figured out what my issue was. I was defining CONFIG_IPADDR in my config .h file and also added ipaddr=xxx.xxx.xxx.xxx to my defined environment variables list in the config .h file. I did not realize that the ipaddr environment variabe (along with others) are added in the variable list in the env_common.c file. As a result I was starting out with duplicate variables before every setting 'ipaddr'.
