Building the toolchain
As root
apt-get install git autoconf build-essential gperf bison flex texinfo libtool libncurses5-dev wget gawk mkdir /opt/Espressif chown $username /opt/Espressif (replace $username with the name of the local user)
as local user
/opt/Espressif git clone -b lx106 git://github.com/jcmvbkbc/crosstool-NG.git cd crosstool-NG ./bootstrap && ./configure --prefix=`pwd` && make && make install ./ct-ng xtensa-lx106-elf ./ct-ng build
Setting up the SDK
- download esp8266_sdk_v0.9.1.zip
- download esp-0.0.2.zip from the forum
- extract esp8266_sdk_v0.9.1.zip to /opt/Espressif/ESP8266_SDK
- extract esp-0.0.2.zip in to /opt/Espressif/ESP8266_SDK/
Making the ESP tool
cd esptool
change the line TARGET_ARCH to LINUX
make
Prepping the at example
comment the line #include user_config.h from /opt/Espressif/ESP8266_SDK/include/osapi.h
cd ~ mkdir esp_sources cd esp_sources cp -R /opt/Espressif/ESP8266_SDK/examples/at at cd at wget -O Makefile https://gist.githubusercontent.com/zarya/7e1a08160bf3b7ac220f/raw/a58ed9a1243dece92b671062bb16555844b326ab/gistfile1.mak make
now upload the files in firmware directory to the module with esptool.py ( https://github.com/themadinventor/esptool/ )
