You mean protect off 0 0x40000 ? (0x3ffff makes no sense)

Did you not overwrite the env? The env is at 0x40000 in the flash.

163 #define CONFIG_SYS_MONITOR_BASE         0x0
164 #define CONFIG_SYS_MONITOR_LEN          0x80000
165 
166 #define CONFIG_ENV_ADDR                 \
167                         (CONFIG_SYS_MONITOR_BASE + CONFIG_SYS_MONITOR_LEN)
168 #define CONFIG_ENV_SIZE                 0x40000
169 #define CONFIG_ENV_SECT_SIZE            0x40000
170 #define CONFIG_ENV_ADDR_REDUND          (CONFIG_ENV_ADDR + 
CONFIG_ENV_SECT_SIZE)
171 #define CONFIG_ENV_SIZE_REDUND          (CONFIG_ENV_SIZE)
