ESP8266 OTA升级MAKEFILE常见问题之一（非常重要）
FOTA对应的flash空间分配如图所示：
对应的下载地址如图：
FOTA的下载地址和运行地址如果不对应，则升级程序可能会出现问题
比如说，我的SPI FLASH大小为4097KB，bin文件编译的时候makefile选的是512+512KB的，则user1升级user2，运行地址是0x81000，但是在烧写烧写程序的时候选择1024+1024KB，则升级完成后从0x101000地址运行，会出现一直复位问题，如图所示
那么，我们如果清楚makefile编译生成的bin文件的配置，则就好办多了，如下代码所示

BOOT?=new
APP?=1
SPI_SPEED?=40
SPI_MODE?=QIO
SPI_SIZE_MAP?=6
#用来配置生成bin文件属性
#BOOT=none，则表示没有boot.bin，不支持云端升级
#APP=1表示生成user1，APP=2表示生成user2
#SPI-SPEED配置烧录时对应的频率
#SPI_MODE配置烧录的SPI方式，这个具体看硬件
#SPI_SIZE_MAP配置生成bin的映像文件地址
#2：FLASH容量1024KB，user1地址0x1000,user2地址0x81000
#3：FLASH容量2048KB，512+512KB,user1地址0x1000,user2地址0x81000
#4:FLASH容量4096KB，512+512KB,user1地址0x1000,user2地址0x81000
#5：FLASH容量2048KB，1024+1024KB，user1地址0x1000,user2地址0x101000
#6：FLASH容量4048KB，1024+1024KB，user1地址0x1000,user2地址0x101000
#其他：512KB，user1地址0x1000,user2地址0x41000
#如果烧录时，对应的FLASH SIZE类型与输出的bin文件配置不同，在升级后，跳转user2时，由于地址不对，会出现错误，一直复位

注意：makefile中的SPI FLASH SIZE值改了之后，一定要clean一下，否则下载程序后上电一直复位错误
