[Hackrf-dev] firmware development

[Sukandar Kartadinata]

Hi,
I’ve just managed to install the toolchain for building custom firmware under Mac OS X.
Here’s some notes (maybe useful for others trying to do this) and one problem:

1. Make sure when you download libopencm3 from https://github.com/mossmann/libopencm3/ that it ends up in the libopencm3 folder of the HackRF distribution
This might be obvious for some, but I had to find out the hard way…

2. Building libopencm3 requires yaml. Make sure your Python install includes it. Mine didn’t.
(if your Python install script (easy_install / pip) can’t find yaml - you have to pick one of the packages that are listed when doing a search for it. I went for PyYAML)

3. When you cd into the blinky folder for your first build:
just typing ‘make’ as the Wiki suggests (https://github.com/mossmann/hackrf/wiki/Firmware-Development-Setup)
won’t work. The build system uses cmake so you have to do that first. The steps are explained in the Readme.

After that I got a working blinky.bin, hooray!

Now here’s the one problem:
When the build system tries to make the .dfu version I only get the help message from dfu-suffix, i.e. it lists its options, so somehow it seems to be invoked in a wrong way.

Here’s the relevant line in […]/blinky/build/CMakeFiles/blinky.dfu.dir/build.make

	dfu-suffix --vid=0x1fc9 --pid=0x000c --did=0x0 -s 0 -a _tmp.dfu

Any suggestions?

Thanks,
Sukandar
