5 years ago 以上打印波特率74880，可以看到 boot能运行，但是识别到的flash大小不正确，实际是1MB的flash，识别到的是512KB，
从打印信息rf_cal[0] !=0x05,is 0xFF 来看，应该是有些地方没有初始化，导致程序一直重启。在windows烧录软件中可以找到这个文件。
D:\vm\flash_download_tools_v3.6.4_0\FLASH_DOWNLOAD_TOOLS_V3.6.4\init_data\ESP8266_RF_init.xls
可以看到第一个值为0x5,所以你的工具肯能就只这个地方导致不能跑起来. 请一起看看这个问题，谢谢

HI,我这边使用你的工具下载8266固件，烧录无任何问题，但是烧录后从flash重启就一直出现复位，复位信息如下：我确定我的固件没有问题，因为同样的固件在windows下烧录，模块可以正常启动，但是在linux上使用你的工具，就会不停重启，请看看什么原因。我的烧录指令是 ./esptool -cf esp8266.bin
