+This repository provides integration scripts to build complete standalone
|
|
|
+SDK (with toolchain) for software development for Espressif ESP8266,
|
|
|
+ESP8266EX chips.
|
|
|
+
|
|
|
+Complete SDK consists of:
|
|
|
+
|
|
|
+1. Xtensa lx106 architecture toolchain (100% OpenSource), based on
|
|
|
+following projects:

|
|
|

+https://github.com/jcmvbkbc/newlib-xtensa
|
|
|
+https://github.com/tommie/lx106-hal
|
|
|
+
|
|
|
+The sourcecode above originates from work done directly by Tensilica Inc.,
|
|
|
+Cadence Design Systems, Inc, or their contractors.
|
|
|
+
|
|
|
+2. ESP8266 IoT SDK from Espressif Systems. This component is only partially
|
|
|
+open source, some libraries provided as binary blobs.

|
|
|
+
|
|
|
+OpenSource components of SDK are based on:
|
|
|
+
|
|
|
+lwIP, http://savannah.nongnu.org/projects/lwip/
|
|
|
+Contiki, http://www.contiki-os.org/
|
|
|
+axTLS, http://axtls.sourceforge.net/

|
+Building
|
|
|
+========
|
|
|
+
|
|
|
+To build standalone SDK with toolchain, you need GNU/POSIX system (Linux,
|
|
|
+BSD, MacOSX, Windows with Cygwin) with standard GNU development tools
|
|
|
+installed, like gcc, binutils, flex, bison, etc.
|
|
|
+
|
|
|
+To start build process run:
|
|
|
+
|
|
|
+ make
|
|
|
+
|
|
|
+This will download all necessary components and compile them. Once done,
|
|
|
+the toolchain (with Xtensa HAL library) will be available in toolchain/
|
|
|
+directory. Add its bin/ subdirectory to execute "xtensa-lx106-elf-gcc"
|
|
|
+and other tools.
|
|
|
+
|
|
|
+ESP8266 SDK will be installed in sdk/, to use it, run the compiler with
|
|
|
+corresponding include and lib dir flags:
|
|
|
+
|
|
|
+xtensa-lx106-elf-gcc -I$(THISDIR)/sdk/include -L$(THISDIR)/sdk/lib
