I tested this patch and tried to run it on my LicheePi Nano. It works, but I found there is WARNINGs when compile the code: ------- include/configs/sunxi-common.h:128:0: warning: "CONFIG_ENV_SECT_SIZE" redefined #define CONFIG_ENV_SECT_SIZE 0x1000
In file included from ././include/linux/kconfig.h:4:0, from <command-line>:0: include/generated/autoconf.h:296:0: note: this is the location of the previous definition #define CONFIG_ENV_SECT_SIZE 0x1
In file included from include/configs/suniv.h:12:0, from include/config.h:4, from include/common.h:16, from lib/slre.c:24: -------- And I think the problem is the CONFIG_ENV_SECT_SIZE should be (and required to) defined in the config file rather than at include/configs/sunxi-common.h:128
