Answer 1

OK, finally I got the answer by myself...

first thing we occured in this issue is got below warning when execute emulator.

WARNING: SD Card files must be at least 9MB, ignoring /dev/sdX

after traced the source code in main.c,

   if (size < 9*1024*1024ULL) {
           fprintf(stderr, "### WARNING: SD Card files must be at least 9MB, ignoring '%s'\n", opts->sdcard);
        } else {
            hw->hw_sdCard_path = ASTRDUP(opts->sdcard);
        }

I ignored the if condition, i.e. force execute hw->hw_sdCard_path = ASTRDUP(opts->sdcard);

then, everything go right:)
