This guide explains how to build applications for Texas Instruments CC3200 LaunchPad (further, CC3200) based on the Kaa C SDK.
Before building the C SDK for the CC3200 platform on Linux, you need to perform the following installation.
Install the GNU toolchain for ARM: gcc-arm-none-eabi
wget https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q2-update/+download/gcc-arm-none-eabi-4_9-2015q2-20150609-linux.tar.bz2 tar -xjf gcc-arm-none-eabi-4_9-2015q2-20150609-linux.tar.bz2 sudo mkdir /opt/kaa sudo chown <username>:<usergroup> /opt/kaa mv gcc-arm-none-eabi-4_9-2015q2 /opt/kaa/gcc-arm-none-eabi
Install and configure OpenOCD, which is needed for running and debugging applications.
Install OpenOCD.
sudo apt-get install openocd
Add a rule file.
cd /etc/udev/rules.d/ sudo nano 98-usbftdi.rules
Write the following code into the added rule file and then save the file.
SUBSYSTEM=="usb", ATTRS{idVendor}=="0451", ATTRS{idProduct}=="c32a", MODE="0660", GROUP="dialout", RUN+="/sbin/modprobe ftdi-sio" RUN+="/bin/sh -c '/bin/echo 0451 c32a > /sys/bus/usb-serial/drivers/ftdi_sio/new_id'"
Reload the rules.
sudo udevadm control --reload-rules
To use Openocd as a regular user, add yourself to the dialout group.
sudo usermod -a -G dialout <username>
Log out and log in to finish the process.
NOTE: The board should be enumerated as /dev/ttyUSB{0,1}
. Use ttyUSB1
for UART.
Install CC3200SDK.
Install Wine.
sudo apt-get install wine
Download CC3200 SDK.
Unpack CC3200 SDK.
wine /home/<user>/Downloads/CC3200SDK-1.2.0-windows-installer.exe cp -R <where_sdk_is_installed>/cc3200-sdk /opt/kaa
Change the configuration file for the debug interface.
In /opt/kaa/cc3200-sdk/tools/gcc_scripts/cc3200.cfg
replace the following few lines
interface ft2232 ft2232_layout luminary_icdi ft2232_device_desc "USB <-> JTAG/SWD" ft2232_vid_pid 0x0451 0xc32a
with
interface ftdi ftdi_device_desc "USB <-> JTAG/SWD" ftdi_vid_pid 0x0451 0xc32a ftdi_layout_init 0x00a8 0x00eb ftdi_layout_signal nSRST -noe 0x0020
Edit GDB configuration.
sed -i 's#-f cc3200.cfg#-f /opt/kaa/cc3200-sdk/tools/gcc_scripts/cc3200.cfg#g' /opt/kaa/cc3200-sdk/tools/gcc_scripts/gdbinit
Before building the C SDK for the CC3200 platform on Windows, you need to perform the following installation.
Archive/unzip
Archive/zip
Devel/autoconf
Devel/automake
Devel/libtool
Devel/subversion (Note: if using TortoiseSVN/Windows7, skip this file)
Devel/make
Devel/gcc-core
Devel/gcc-g++
Devel/mingw-gcc-core
Devel/mingw-gcc-g++
To enable debugging for your CC3200 applications, you will also need to build OpenOCD as described in the official CC3200-Getting_Started_Guide (item 3.3.3)
For more information, please refer to the official CC3200-Getting_Started_Guide.
Building C SDK for Linux
Before creating applications based on the C SDK, you should obtain the C SDK and build a static library from it. To do so, generate the C SDK in Admin UI, then extract the archive, cd
to it and execute the following for Linux:
mkdir -p build cd build cmake -DKAA_PLATFORM=cc32xx -DCMAKE_TOOLCHAIN_FILE=../toolchains/cc32xx.cmake .. make
For more details on building the C SDK for Linux, please refer to this page.
Building C SDK for Windows
Open the cygwin terminal and execute the following:
mkdir -p build cd build cmake.exe -G "Unix Makefiles" -DKAA_PLATFORM=cc32xx -DKAA_TOOLCHAIN_PATH=c:/cygwin/opt/kaa -DCMAKE_TOOLCHAIN_FILE=../toolchains/cc32xx.cmake .. make
To quickly start with the Kaa IoT platform, you can download one of the Kaa demo applications from the Kaa Sandbox and run it on the CC3200 board. We recommend that you start with the ConfigurationDemo.
Connect CC3200 LaunchPad to your PC through a micro-USB connector and execute the following in your terminal:
tar -xzf configuration_demo.tar.gz cd CConfigurationDemo ./build.sh build
To launch the application, execute the following:
/opt/kaa/gcc-arm-none-eabi/bin/arm-none-eabi-gdb -x /opt/kaa/cc3200-sdk/tools/gcc_scripts/gdbinit build/demo_client.afx
NOTE: If you want to see the debug output in the terminal, make sure to get connected to /dev/ttyUSB{0,1}.
Jumpers on the CC3200 board should be connected as shown below.
To run an application, remove SOP2 and J8 jumpers, and then connect J2 and J3 jumpers.
For more information, see the official UniFlash Quick Start Guide.
