2nd boot version : 1.2
SPI Speed : 40MHz
SPI Mode : QIO
SPI Flash Size : 4Mbit
jump to run user2


您好，

1. 建议您使用最新版本的 boot，目前最新的版本是 boot_v1.4(b1).bin，新版本的 boot 在 user2 无法运行时，会跳回 user1 运行。
2. 从您提供的 log 看来，您的 flash size 是 4Mbit=512KB，但您编译时 Step 5 选择的却是1024KB。如果您确认您的 Flash size 实际为 1024KB，请您使用 Espressif 官方的 flash download tool，烧录时选择 Flash size 8Mbit.

如果您的问题仍未解决，麻烦提供烧录时的 flash download tool 截图，和运行时异常的 log，以供分析。

感谢您对 ESP8266 的关注！

0x00000 boot_v1.2.bin
0x01000 user1.1024.new.2.bin
把user1.bin和user2.bin都上传到了自己的服务器上，大家谁还遇到过一样的问题，求指教！
我选择的是1024KB，还需要在代码哪里设置一下吗？
另外，我看有人提到boot区分正常模式和增强模式，请问如何设置boot进入不同的模式？
