Getting Contiki git repo and compiling web-demo for TI Sensortag in linux works quite well. Flashing it not so. Recommended way is to
transfer image to windows and flash from there, but it's possible to flash from linux commandline also. Using Code Composer Studio (CCS) makes job much easier, and you can also debug your code, at least in theory.
CCS can import project with makefile-style compiling (File -> Import -> C/C++ -> Existing Code as Makefile Project). Unfortunately it only can understand simple Makefile and Contiki uses include etc. Even when you can compile image, CCS will complain lot's of errors and warnings. It's quite bizarre situation. One way to 'fix' it, is defining things in makefiles to headers so CCS known what is actually defined when compiling. Like adding to project-conf.h:
/* for CCS as it can't detect this from Makefile.include */
#define NETSTACK_CONF_WITH_IPV6 1
/* CCS uses wrong button-sensor.h */
#ifndef BUTTON_SENSOR_VALUE_DURATION
#define BUTTON_SENSOR_VALUE_DURATION 1
#endif
Also finding source files can be a bit tricky. Adding whole contiki would be simple way so solve this but CCS don't like adding parent of project. Way around is adding links (to project) to needed subdirectories:
project -> properties -> c/c++ general -> Paths.. -> Source Location -> Link Folder
apps, cpu/cc26xx-cc13xx, core, platform/stf06-cc26xx
Also in c/c++ build -> settings you can enable gnu-versions of parsers.
You can also add Makefile.include from top, but it only makes editing easier (project -> Add Files -> Link).
Also you need to get debug-symbols to elf, so add Makefile:
CFLAGS+=-g
LDFLAGS+=-g
Nice. Now it doesn't complain and (most) code it shows is actually right one. To debug you need to create .ccxml target configuration file (project -> New).
Note that when you connected Debug DevPack to PC, it shouldn't have SensorTag2 connected to it. After board have booted (green led on) connect SensorTag2. Also when debugging first time, Debug DevPack firmware is updated to newest one.
Start debugger. Change Debug -> .ccxml -> Edit.. -> Program -> Cortex_M3_0 Project to project root and Program to .elf file. Check that run to symbol main is set. Next start of debug should then automagically load & run to main(). If it doesn't automatically load image to SensorTag2, you can choose Load & select elf.
Unfortunately good things stops there. For some reason JTAG connection to SensorTag2 seems to disconnect really often. Even dropping it's speed from 2.5MHz to 100kHz doesn't help :( This is probably due eclipse blocking and emulation package then misses something from JTAG/Debug DevPack. Hopefully future update fixes (some of) this.

is that same setting applicable for CCS in windows.

Obtaining the Contiki git repository and building the web demo for the TI Sensortag on Linux is very successful. Nevertheless, flashing the device is not as simple. The preferred approach is to move the image onto Windows and flash it from there, although flashing can also be done from the Linux command line. In theory, utilizing Code Composer Studio (CCS) greatly simplifies the process and enables you to debug your code. If you are in search of high-quality screen printing services, there are excellent choices to consider.
