[tr][td]I got a BPI G1 development board, and succeeded in ubuntu14.04 running demo, I will share my experiences and joy

Download cc3200sdk
download SimpleLink Wi-Fi CC3200 Software Development Kit (SDK), but is exe format, so I can only be installed in the windows, and then copy it to linux -
Configuring the LaunchXL JTAG Debug Interface
The debug interface is provided by an FTDI FT2232 chip with custom vendor and product IDs. To make it accessible for the Linux system, there is an udev rule needed: /etc/udev.rules.d/99-tiftdi.rules
ATTRS{idProduct}=="c32a", ATTRS{idVendor}=="0451", RUN+="echo 0451 c32a > /sys/bus/usb-serial/drivers/ftdi_sio/new_id", MODE="666", GROUP="plugdev"
With the ftdi-sio module loaded (by the above udev rule or otherwise), I get two /dev/ttyUSBx devices when the Launchpad is plugged in。
- Build and install openOCD (Open On-Chip Debugger)
Building and installing openOCD is the standard “./configure; make; sudo make install”，I Using OpenOCD in version 0.8.0。Libusb installed before compiling。
sudo apt-get install libusb-1.0.0-dev
Then, execute the command：
cd <openOCD source tree>
./configure
make
sudo make install
After a successful installation shown
Using OpenOCD in version 0.8.0, the configuration file for the debug interface needs to be changed.
In ~/CC3200_SDK/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
by
interface ftdi
ftdi_device_desc "USB <-> JTAG/SWD"
ftdi_vid_pid 0x0451 0xc32a
ftdi_layout_init 0x00a8 0x00eb
ftdi_layout_signal nSRST -noe 0x0020
Then, you need to configure the G1, as shown in Figure
starting OpenOCD with the following command:
openocd -f ~/CC3200_SDK/cc3200-sdk/tools/gcc_scripts/cc3200.cf
shows the following message:

- Download arm-none-eabi Cross Tool Chain
The arm-none-eabi cross tool chain will enable you to compile, link and debug source code destined to run on the CC3200 arm microcontroller.
Download the prebuilt binaries of the arm-none-eabi cross tool chain for Linux from launchpad.net. Unpack it to an appropriate directory and add the bin/ directory to the execution path.
tar xvjf gcc-arm-none-eabi-4_8-2014q2-20140609-linux.tar.bz2
export PATH=$PATH:~/gcc-arm-none-eabi-4_8-2014q2/bin
- Compile and debug getting_started_with_wlan_station
Edit the OpenOCD start command in ~/CC3200_SDK/cc3200-sdk/tools/gcc_scripts/gdbinit to make shure OpenOCD finds it’s appropriate configuration file.
Mine looks like this:
target remote | openocd -c "gdb_port pipe; log_output openocd.log" -f ~/CC3200_SDK/cc3200-sdk/tools/gcc_scripts/cc3200.cfg
Compile getting_started_with_wlan_station
cd ~/CC3200_SDK/cc3200-sdk/example/getting_started_with_wlan_station/gcc
make
Then compile the information appears as follows
CC ../main.c
CC ../pinmux.c
CC ../../common/gpio_if.c
CC ../../common/uart_if.c
CC ../../common/startup_gcc.c
LD exe/wlan_station.axf
Install minicom and open ttyUSB1
minicom -D /dev/ttyUSB1
Run a gdb session
cd ~/CC3200_SDK/cc3200-sdk/example/getting_started_with_wlan_station
arm-none-eabi-gdb -x ~/CC3200_SDK/cc3200-sdk/tools/gcc_scripts/gdbinit gcc/exe/wlan_station.axf
