python hackrf_HackRF固件更新及编译环境搭建
1 HackRF Host 软件更新
git pull
cd host
mkdir build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo ldconfig
2 HackRF固件更新
如果不想自己编译固件, 可以直接从https://github.com/mossmann/hackrf/releases把最新打好的包下载下来, 解压, 里面有firmware-bin目录, 是已经编译好的固件.
更新Flash:
hackrf_spiflash -w hackrf_one_usb_rom_to_ram.bin
更新CPLD:
hackrf_cpldjtag -x hackrf_cpld_default.xsvf
3 HackRF固件编译环境搭建
dfu-util: 需要从代码中checkout编译安装, 由于兼容性问题, 目前只能使用0.7版本的dfu-util, 见Issue
git clone https://github.com/rad1o/dfu-util.git
git log --grep "Release 0.7"
git checkout 4e312c5567a84f76654295c267ec35f71727fe5a
./autogen.sh
./configure
make
sudo make install
安装yaml
sudo apt-get install python-yaml
由于gcc-arm-none-eabi是i386架构的, 所以需要i386运行时
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libgcc1:i386 gcc-4.6-base-i386 libstdc++5:i386 libstdc++6:i386
从Launchpad上下载gcc-arm-none-eabi, 解压到任意的路径中. 注意, Debian源里的gcc-arm-none-eabi貌似不能用.
然后在.bashrc里加入路径:
export PATH=$PATH:/path/to/gcc-arm-none-eabi-4_9_2015q2/bin
接下来就可以编译了, 记得要先把libopencm3拉下来编译. 参阅此处.
git submodule init
git submodule update
cd firmware/libopencm3
make
编译固件并写入
cd firmware/hackrf_usb
mkdir build
cmake .. -DBOARD=HACKRF_ONE
make
hackrf_spiflash -w hackrf_usb.bin
3.1 DFU 测试
cmake .. -DBOARD=HACKRF_ONE -DRUN_FROM=RAM
cd hackrf/firmware/build/blinky
dfu-util --device 1fc9:000c --alt 0 --download blinky.dfu
Tips: DFU mode. If cannot find
1fc9:000c NXP Semiconductors
You may need to power the board up with DFU key pressed down, then press reset with DFU on.
