安装MAC编译工具链

1. 安装brew
2. 安装命令行工具前安装最新版本Xcode(>=8.3)
3. 安装相关工具

$ brew tap homebrew/dupes
$ brew install binutils coreutils automake wget gawk libtool help2man gperf gnu-sed --with-default-names grep
$ export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

1. 安装MacPort下载地址与gsed

export PATH=/opt/local/bin:$PATH
export PATH=/opt/local/sbin:$PATH
sudo port -v selfupdate
port install gsed

1. 创建大小写敏感的文件系统，MAC默认文件名不区分大小写

$ sudo hdiutil create ~/Development/esp-open-sdk.dmg -volname "esp-open-sdk" -size 5g -fs "Case-sensitive HFS+"
$ sudo hdiutil mount ~/Development/esp-open-sdk.dmg
$ cd /Volumes/esp-open-sdk

1. 下载esp-open-sdk编译工具源码

git clone https://github.com/pfalcon/esp-open-sdk.git --recursive

1. Linux切Mac的一些修改
   (==注意这里用的sed命令是Mac下的，不是gsed，如果执行失败把sed替换成/usr/bin/sed==)

cd esp-open-sdk
sed -i.bak '1s/^/gettext=\'$'\n/' crosstool-NG/kconfig/Makefile
sed -i.bak -e 's/[[:<:]]sed[[:>:]]/gsed/' Makefile
sed -i.bak -e 's/[[:<:]]awk[[:>:]]/\$(AWK)/' lx106-hal/src/Makefile.am
sed -i.bak 's/AM_PROG_AS/AM_PROG_AS\'$'\nAM_PROG_AR/' lx106-hal/configure.ac

1. 开始编译

make STANDALONE=n

分析/Volumes/esp-open-sdk/esp-open-sdk/crosstool-NG/build.log定位源码newlib.sh 12行，原因为下载失败

do_libc_get() {
    local libc_src="{http://mirrors.kernel.org/sourceware/newlib,
                     ftp://sourceware.org/pub/newlib}"

    if [ "${CT_LIBC_NEWLIB_CUSTOM}" = "y" ]; then
        CT_GetCustom "newlib" "${CT_LIBC_VERSION}"      \
                     "${CT_LIBC_NEWLIB_CUSTOM_LOCATION}"
    else # ! custom location
        if echo ${CT_LIBC_VERSION} |${grep} -q linaro; then
            YYMM=`echo ${CT_LIBC_VERSION} |cut -d- -f3 |${sed} -e 's,^..,,'`
            CT_GetFile "newlib-${CT_LIBC_VERSION}" ${libc_src} \
                       https://releases.linaro.org/${YYMM}/components/toolchain/newlib-linaro \
                       http://cbuild.validation.linaro.org/snapshots
        else
            CT_GetFile "newlib-${CT_LIBC_VERSION}" ${libc_src} \
                       http://mirrors.kernel.org/sources.redhat.com/newlib
        fi
    fi # ! custom location
}

解决方法：去http://mirrors.kernel.org/sourceware/newlib手动下载newlib-2.0.0.tar.gz，放至 /Volumes/esp-open-sdk/esp-open-sdk/crosstool-NG/.build/tarballs目录，再重新执行编译

1. 将生成的交叉编译工具xtensa-lx106-elf加到环境变量

vim $HOME/.bash_profile
export PATH=$PATH:/esptools/esp-open-sdk/xtensa-lx106-elf/bin
source $HOME/.bash_profile

编译

1. 进入esp8266代码目录，执行下面命令开始编译

make COMPILE=gcc

烧录

安装usb转串口驱动(比如PL2303)

1. 下载驱动
2. 安装
3. 安装完成，重启电脑之后我们在“网络偏好设置”中，发现多了一项USB-SerialController
4. 终端执行下面命令查看，tty.usbserial就是我们的设备

192:dev shenhaibo$ cd /dev
192:dev shenhaibo$ ll tty.*
crw-rw-rw-  1 root  wheel   20,   0  4  9 11:02 tty.Bluetooth-Incoming-Port
crw-rw-rw-  1 root  wheel   20,   2  4  9 11:04 tty.usbserial

固件下载工具配置

1. 下载源码

git clone https://github.com/themadinventor/esptool.git

1. 配置环境变量

vim $HOME/.bash_profile
export PATH=$PATH:/Users/shenhaibo/Development/ESP6288/esptool
source $HOME/.bash_profile

1. 安装PySerial下载地址

tar xfvz pyserial-2.7.tar.gz
cd pyserial-2.7
sudo python setup.py install

固件下载工具使用

1. 擦除芯片

sudo esptool.py --port /dev/tty.usbserial erase_flash

1. 下载固件

sudo esptool.py --port /dev/tty.usbserial write_flash -fm dio -fs 32m -ff 40m 0x00000 ~/Desktop/nodemcu_float_0.9.6-dev_20150704.bin
