Building Firmware
The PortaPack has its own firmware. You may use a prebuilt package. If you prefer to build from scratch, here's how:
You will need a few tools installed on your computer before you begin.
- GCC-ARM-Embedded - I am using the "9-2019-q4-major" release.
- CMake 2.8.9 or newer - Build system now uses CMake instead of GNU Make.
- PyYAML for your default version of Python (used by libopencm3, built by hackrf submodule).
- dfu-util 0.7 or newer - Used to load and run the stock HackRF firmware from RAM.
The source code is hosted on GitHub. Change to a directory where you want the source code, and clone the source repository.
git clone --recurse-submodules https://github.com/sharebrained/portapack-hackrf.git
Change directories into the cloned repository.
cd portapack-hackrf
Make a "build" directory and initialize the CMake build files into that directory:
mkdir build
cd build
cmake ..
Make the SPI flash binary image (which builds the bootstrap, application, and baseband binaries):
make firmware
The binary will be at "firmware/portapack-h1-firmware.bin".
Once you have built the binary, you must program it into the HackRF One SPI flash.
Plug the HackRF into a USB port on your computer.
Hold down the HackRF DFU button. Press and release the HackRF reset button. Wait a second or two. Then release the DFU button. The HackRF is now in DFU mode.
Program the HackRF's SPI flash:
make program
When finished, press the reset button on the HackRF. The PortaPack code is now running from the SPI flash on the HackRF.
