TL;DR: Files are in Releases
This serves to archive the ARM GCC for bare-metal Cortex-M and Cortext-R, or as ARM calls it the GNU Arm Embedded Toolchain, built by them (when available) or us.
When we build it we use their source package and build instructions, changing as little as possible, to get the binaries for the build target only (IOW, we don't cross-compile for Windows from Raspberry Pi for the armv7l target).
The files are in the Releases area of this repo GitHub -> synthetos/gcc-arm-none-eabi-archive.
The original files can be found here on ARM's web site. Note that in a few cases (currently armv7l target only) they don't provide pre-built binaries, and we've built them from the src download provided by ARM.
These files are provided AS-IS, and are simply copies of what are provided by ARM. This, in order to report a problem with the software, please report bugs though their system.
If you find a file missing, misnamed, or inaccurately described, then please open an issue on this repo.
