有人可以指导在Linux（特别是Ubuntu）中为MSP430设置工具链的程序吗？我正在使用MSP430启动板（MSP-EXP430G2），我需要设置编译器/构建工具和调试器驱动程序。

如果您安装德州仪器的CCS IDE，Linux版本，它将安装工具链。但是，在Linux中开发MSP430时还存在其他问题。错误和修复在我的帖子中详细说明：
MSP430 / eZ430-RF2500 Linux support Guide
"Compile code using Code Composer Studio (CCS)
Download CCS for Linux.
Create a new CCS project with a Custom MSP430 Device or any other.
Compile the code. The result binary image will be in the workspace. The workspace path can be found in “File” / “Switch workspace”.
The file that should be programmed to the device is the project-name.out file.
Program and run device using mspdebug
Download and Install mspdebug
From the directory with the file project-name.out run:
$ sudo mspdebug rf2500
Now you are in mspdebug’s command line shell. Run the following to program and run the device:
(mspdebug) prog project-name.out
(mspdebug) run
Use Ctrl+c to pause run and get command line back.
Fix a Linux Kernel bug that prevents Minicom to communicate with device
The device path in /dev is /dev/ttyACM0. Currently, connecting to it
serially using utilities such as minicom is not possible, and you get the message “/dev/ttyACM0: No such file or directory”.
The bug is in Kernel module “cdc_acm”. The solution is to fix the bug in the source code, recompile the module and plug it instead of the existing one.
Find out Linux version:
$ uname -r
cdc_acm’s source is the files cdc-acm.c and cdc-acm.h. They are under the Linux path drivers/usb/class/.
Download these two files from a repository that matches your Linux version. Such repos are available in lxr.free-electrons.com and www.kernel.org.
Create a new directory and move the files to it.There are two code segments need to be removed or commented out:
The next lines appear in function “acm_port_activate()” on newer versions and in “acm_tty_open()” in older ones:
// if (0 > acm_set_control(acm, acm->ctrlout = ACM_CTRL_DTR | ACM_CTRL_RTS) &&
// (acm->ctrl_caps & USB_CDC_CAP_LINE))
// goto bail_out;
The next line appears in function “acm_port_shutdown()” on newer versions “acm_port_down()” in older ones:
// acm_set_control(acm, acm->ctrlout = 0);
Create a Makefile and compile:
$ echo 'obj-m += cdc-acm.o' > Makefile
$ make -C /lib/modules/`uname -r`/build M=$PWD modules
You should have a new cdc-acm.ko file in the directory
Replace the existing module (This change will be discarded after boot):
$ sudo rmmod cdc-acm
$ sudo insmod ./cdc-acm.ko
Communicate via the serial port using Minicom
Launch minicom setup from command line:
$ minicom -s
In the menu, choose:
Serial port setup
Press ‘A’ (for “Serial Device”).
Replace Current device path with:
/dev/ttyACM0
Press ‘E’ (for “Bps/Par/Bits”).
Set the correct data rate for your device.To lower the rate (to 1200, for instance), keep pressing ‘B’ (for “previous”) until the top line shows:
Current: 1200 8N1
Press “Enter” until returning to main menu, there, press “Exit”.This will exit the setup menu and start running on the device. From now on you should see messages over the serial connection: It is up to you to program the device with such messages."
