pusrdata HTTP/1.1 200 OK
Server: Apache-Coyote/1.1

when esp restarted , first i use the api to print information about USER.BIN and BIN addr like this:
printf("ESP Flash Size:%d\n",system_get_flash_size_map());
printf("ESP UserBin Addr:%d\n", system_get_userbin_addr());
but esp have already restarted from USER1.BIN like this:
ESP Flash Size:2
ESP UserBin Addr:4096
espFsInit test 0x3fff5420

USER1.BIN and USER2.BIN have different offset addrs, ox1000 is the USER1.BIN ,so
the question is : why not esp start from USER2.BIN after reboot because of FOTA?
Thanks!
