安装MAC编译工具链

安装brew安装命令行工具前安装最新版本Xcode(>=8.3)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:$PATH" 安装MacPort下载地址与gsed export PATH=/opt/local/bin:$PATH export PATH=/opt/local/sbin:$PATH sudo port -v selfupdate port install gsed 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 下载esp-open-sdk编译工具源码 git clone https://github.com/pfalcon/esp-open-sdk.git --recursive 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 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

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

进入esp8266代码目录，执行下面命令开始编译 make COMPILE=gcc

安装usb转串口驱动(比如PL2303)

下载驱动安装安装完成，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

下载源码 git clone https://github.com/themadinventor/esptool.git 配置环境变量 vim $HOME/.bash_profile export PATH=$PATH:/Users/shenhaibo/Development/ESP6288/esptool source $HOME/.bash_profile 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

擦除芯片 sudo esptool.py --port /dev/tty.usbserial erase_flash 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
