This PPA has several compiler versions and platforms available. For many hardware platforms (notably Naze)
the 4.9.3 compiler will work fine. For some, older compiler 4.8 (notably Sparky) is more appropriate. We
suggest you build with 4.9.3 first, and try to see if you can connect to the CLI or run the Configurator.
If you cannot, please see the section below for further hints on what you might do.

## Bricked/Bad build?
Users have reported that the 4.9.3 compiler for ARM produces bad builds, for example on the Sparky hardware platform.

sudo dpkg -i gcc-arm-none-eabi_4-8-2014q2-0saucy9_amd64.deb

Make sure to remove `obj/` and `make clean`, before building again.

## Notes Credit goes to K.C. Budd, AKfreak for testing, and pulsar for doing the long legwork that yielded this very short document.
There are compiler issues with at least the Sparky target.
