在linux下构建msp430 launchpad开发环境 [复制链接]

按照网上的方法搭好IAR开发环境，试着跑了一个亮灯的程序，倒是很顺利，但是问题也来了，我的Windows8系统上驱动还是比较匮乏，好不容易装上模拟器的驱动，但在想使用串口的时候，发现没有我的USB-TTL转换器的驱动，也就读不了温度传感器，加上我本人比较爱好linux，在经过一番纠结之后，终于成功作出了基于mspgcc开发环境，鉴于网络上很缺乏这方面的资料，我在这里给出我的方法。
我的环境是搭建在Fedora17上，开发板是MSP-EXP430G2，芯片是MSP430G2553IN20和MSP430G2452IN20，下载和调试用的是套件里的USB线（和quick start里windows的连接方式差不多），下面主要介绍mspgcc的构建。
我主要参考了这个网页 http://sourceforge.net/apps/medi ... =Install:fromsource
我根据这个页面编写了一个脚本

export PREFIX=/usr
export MAKEFLAGS='-j 5'

#Create a temporary build directory
mkdir msp430-build
cd msp430-build

make
# Do the install as root (e.g., sudo)
make install

#  I have seen issues where the msp430-ranlib doesn't get detected correctly causing build issues later.
#  if that happens uncomment the following:
#  cd /usr/bin
#  sudo ln -s /usr/local/bin/msp430-ranlib

#Configure GCC
cd ../gcc-4.6.3-msp430
../gcc-4.6.3/configure --target=msp430 --enable-languages=c --program-prefix="msp430-"  --prefix=$PREFIX


make
# Do the install as root (e.g., sudo)
make install

#Configure GDB

# Install the mspgcc-libc
cd ../msp430-libc-20120224

#  If you need to disable features, run configure here with any of the following flags to enable/disable features.
#  --disable-printf-int64 : Remove 64-bit integer support to printf formats
#  --disable-printf-int32 : Remove 32-bit integer support from printf formats
#  --enable-ieee754-errors : Use IEEE 754 error checking in libfp functions

cd src
make
# Do the install as root (e.g., sudo)
PATH=$PATH make PREFIX=$PREFIX install
cd ..

# Now let's build the debugger
cd ../mspdebug-0.19
PREFIX=$PREFIX make
# Do the install as root (e.g., sudo)
make install
cd ../..

# ALL DONE

可以根据自己的需要修改PREFIX来改变安装目录
MAKEFLAGS='-j 5'表示5进程编译。
如果没有安装在/usr/的话，需要修改PATH变量来制指定可执行文件的位置

下面是我纠结很久的部分，就是这个环境的使用
编译
msp430-gcc -mmcu=msp430g2553 main.c
根据所用的芯片信号更改-mmcu=的取值
下载和运行(需要root权限)
mspdebug rf2500
>prog a.out
>run
prog命令将制定的程序下载到开发板
run就可以执行，当然你也可以做单步执行等调试操作（不过不能像gdb那样使用r、b等缩写）
我会的也就是这么多，放在这里希望能帮到需要的人。
