Set up the MSP430 Development Environment (MSPGCC) in Ubuntu)

Recently, I accidentally saw a netizen say that the MSP430 also has the GCC compiler, namely, MSPGCC. I also began to think that it is not far from developing the MSP430 in Linux. Google end time, find the MSPGCC Wiki: http://sourceforge.net/apps/mediawiki/mspgcc/index.php? Title = MSPGCC_Wiki and a compiled installation package already exists in Ubuntu. At this point, I do not like to install these tool chains from Ubuntu sources, I prefer the tool chain officially released by MSPGCC, but the official tool chain has not been found for a long time, so now I will first use the Ubuntu installation package, the above link found the Ubuntu link, https://launchpad.net/ubuntu/oneiric/+search? Text = msp430, lp has 6 packages, which are

Msp430-libc:

Standard C library for TI MSP430 development430 C Standard libraryMspdebug:

Debugging tool for MSP430 microcontrollers430 debugging tool, used to connect to the simulatorMCU:

Spec files, headers and linker scripts for TI's MSP430 targets430 header file and link scriptBinutils-msp430:

Binary utilities supporting TI's MSP430 targets430 Binary ToolkitGcc-msp430:

The gnu c compiler (cross compiler for MSP430) 430 GCC compilerGdb-msp430:

The GNU debugger for release 430 GDB debuggerFor more information about the functions of these packages and Their Relationships with GCC, refer to the following post. Http://cms.mcuapps.com/techinfo/toolchains/gcc/we installed it together! Enter:

 

Sudo apt-get install msp430-libc mspdebug MCU binutils-msp430 gcc-msp430 gdb-msp430 gdb-msp430_7.2 but there are some small episodes during the installation process, there will be the following error: dpkg: Processing/var/cache/apt/archives ~ Mspgcc-7.2-20110612-1ubuntu1_i386.deb (-- unpack) error: attempting to overwrite/usr/share/gdb/python/gdb/_ init __. py, which is included in the package gdb 7.4-2012.04-0ubuntu2. 1.

Next, create a new file for compilation. The content is as follows:

Msp430-gcc-OS-mmcu = rjg2553-o led. elf led. c compiled successfully! For online debugging and debugging of eclipse + msp430-gdb, stay tuned.
