ESP8285下载后不运行

[TonyTan]

ESP8285芯片，下载选择DIO，并去除了外置Flash，但是下载完成后硬件切回Flash模式，程序不运行，gpio2打印信息如下：
同样的程序在8266上正常，8285的启动模式设置和8266不一样?

I have found the solution, you must select DOUT mode in Flash Download tool.

hi tony

do you use the esp8285?
how you flash it - with the same flash tool's like esp8266`?

would use this:

Code: Select all

esptool.py --port <serial-port> write_flash -fm dout -fs 1m 0x00000 <firmware>


thanks
best wishes
