Ti has already packaged the CC2652R development environment, saying that it is used, and it is not too much. TI prepared three compilers, for us to choose, the first is TI's own CCS development environment. The second is a famous IAR development environment, and the third is the compilation method of embedded common GCC Makefile. TI has built a perfect support package, we only need to install tools and make the development you need.
Next, we have software installation, install two software SimpleLinkTM SimpleLink SDK and CCS, related downloads are as follows: SimpleLink-CC13x2-26x2-SDK: https://www.ti.com.cn/tool/cn/simplelink- CC13x2-26x2-SDK
CCSTUDIO-WCS: https://www.ti.com.cn/tool/cn/ccstudio-wcs
Here we use GCC Makefile to compile.
First configure the environment, add Tools directory to the environment variable, which can be easily gmake commands.
Enter C: \ ti \ simplelink_cc13x2_26x2_sdk_4_40_04_04 \ kernel \ tirtos \ builds \ cc13x2_cc26x2 \ debug \ gcc directory, make gmake.exe command to compile, this time will find the command does not properly compile, because can not find the tool chain, a Makefile to find It can be found that Gmake is a fixed directory. Since the SIMPLLINKTM SIMPLINK SDK downloaded by the author does not match the version of the CCS, our toolchain is not found, so the author will use the tool to re-copy one, and modify the name of the directory, so our GCC can finally run NS.
The following compiles the kernel, enter C: \ TI \ SimpleLink_cc13x2_26x2_sdk_4_40_04_04 \ kernel \ Tirtos \ builds \ cc13x2_cc26x2 \ debug \ gcc directory, perform Gmake.exe, can see the system is compiling.
Once compiled, you can enter the engineering catalog for compilation.
Use a blank project to test, the directory is as follows:
C: \ Ti \ SimpleLink_cc13x2_26x2_sdk_4_40_04_04 \ Examples \ RTOS \ CC2652RB_LaunchXL \ Drivers \ EMPTY \ Tirtos \ GCC>
After entering the directory, Gmake is also executed. As shown below:
This completes the compilation of a CC2652R project. And get the binary firmware Empty.out of our application.
Open the unified.out tool, select Empty.out, click Start, and complete the update to the developer firmware. Of course, you can also choose to update firmware updates through OTA.
The software section is here to say that the board is difficult to get the difficulty. If you are interested in this Ti LaunchXL-CC26X2R1 development board, you can get more more detailed content in TI official website for you to learn.
