ESP8266 module has been widely used in WiFi networking field, but ESP8266 chip is required Flash plug-chip, thus making the module can not be made smaller. After Lexin company also launched a ESP8285 chip, integrates directly 1MByte of Flash within the chip, and then the manufacturers introduced a smaller module ESP8285, ESP8266 is relative, ESP8285 safer.
Internet basically said ESP8285 and ESP8266 code is fully compatible, can be used directly, but many newcomers have encountered, in the normal operation of the code in ESP8266, ESP8285 burned to the phenomenon can not start, in fact, there are two key areas They were ignored.
Burning part of the change
Before ESP8266 during the programming, SPI Mode setting is most DIO mode, but you need to use ESP8285 DOUT mode, so download burning module when you want to SPI Mode is set to DOUT mode.
Flash Size should be set to 1MByte.
Change compiler before the Makefile
In ESP8266 SDK development package Makefile files in the root directory, the same label to read and write internal SPI Flash configuration of SPI Mode, there also needs to be modified to DOUT for ESP8285.
ESP8266 and ESP8285 difference in the development process on the introduction here, wish you all develop smoothly.
