Installation and Usage
The Software Developer’s Guide provides instructions on how to setup your Linux development environment, install the SDK and start your development. It also includes User’s Guides for various Example Applications.
Host Support
For the specific supported hosts for current SDK, see Supported Platforms.
Note
Processor SDK Installer is 64-bit, and installs only on 64-bit host machine. Support for 32-bit host is dropped as Linaro toolchain is available only for 64-bit machines.
