Hi, Intel Edison has a build warning below. + *env_addr = offset; + ^ w+../env/mmc.c: In function 'mmc_get_env_addr': w+../env/mmc.c:121:12: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized] I did not figure out what is wrong here. v2017.11 does not have such build warning. Do you have any idea? Regards, Bin
