Esp8266 firmware flasher update#

Most of the work is in the non-project specific makefile (letвЂ™s call it вЂњmasterвЂќ makefile) and it is referred to from each project as вЂњ./MakefileвЂќ. We will use EspressifвЂ™s makefile, which is rather convoluted. Since weвЂ™re not going to be modifying the project вЂ“ we just want to build it вЂ“ we also wonвЂ™t rewrite its makefile. So where were we? Oh, right вЂ“ weвЂ™ve got the build environment installed and weвЂ™re going to build our own AT firmware which we will then package into a 1-slot image to be flashed. You may have even tried to cd to /SDK/examples/at and tried to build it, but have received the following message: I develop on Linux, so I wonвЂ™t be covering this route, but it should work just the same.ДЄs our starting point, letвЂ™s assume you have the development environment installed. They also post updates, such as when new SDKs come out. Use ESP OPEN SDK, which gathers all the tools from (1) for you automatically.

Gather the tools yourself (see for example: Russian, Google translated)Дў. For this we will need a way to compile esp8266 projects.

Esp8266 firmware flasher update#

Thus begging the queston: how can one update their AT firmware to the latest version? However, at this point in time (end of May 2015) most of the ESP8266 units out there are of the 512 kB variety. Since SDK version 1.0.1 the binary distribution of AT has become too large to fit on a 512kB flash. Typically one can find a new version of AT firmware in each release of EspressifвЂ™s SDK. It is distributed in binary form by Espressif, but it can also be built from source (binary blobby as it may be). The AT firmware is the default firmware for ESP8266 and provides AT style commands for actions such as join access point and send tcp packet.
