byte2=int(flash_mode)&0xff
byte3=(((int(flash_size)<<4)| int(flash_clk_div))&0xff)

而程序读出来的前4个字节却是E9 03 00 60
写了个小程序将前四个字节改为E9 03 00 20就显示正确了（显示错误的时候，OTA在线升级就不能正常工作了）

怎么回事呢？1.5有问题吗？

勾选SpiAutoSet

对比了一下我的，没啥差别，就是这个改成 不勾选 呢？

flash download tool 烧录工具上的 flash size 选项，没选对吧？

烧写工具2.4，烧写以下几个文件
blank 0xFE000
init 0xFC000
boot 0x0
user1 0x1000
选项如下：
CrystalFreq 40M
SPI SPEED 40M
SPI MODE QIO
FLASH SIZE 8Mbit
勾选SpiAutoSet
不勾选DoNotChgBin

Code:

OS SDK ver: 1.4.0(c599790) compiled @ Feb 26 2016 11:08:14

编译时 SPI_MAP选择是2，编译的输出是：

Code:

Support boot_v1.2 and +
Generate user1.1024.new.2.bin successully in BIN_PATH
boot.bin------------>0x00000
user1.1024.new.2.bin--->0x01000
!!!

所用的FLASH大小为8Mbits

Code:

flash vendor:
EFh : WB
flash devID:
4014h
QUAD;8Mbit
crystal:
40 Mhz

可是启动时显示时：

Code:

2nd boot version : 1.5
  SPI Speed      : 40MHz
  SPI Mode       : QIO
  SPI Flash Size & Map: 32Mbit(1024KB+1024KB)
jump to run user1 @ 1000

OS SDK ver: 1.4.0(c599790) compiled @ Feb 26 2016 11:08:14

这是怎么回事呢？
