The Software Developer’s Guide provides instructions on how to setup up your Linux development environment, install the SDK and start your development. It also includes User’s Guides for various Example Applications and Code Composer Studio.
2.1.10. Host Support¶
The Processor SDK is developed, built and verified on Ubuntu 16.04 and 18.04. Details on how to create a virtual machine to load Ubuntu are described in this page.
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
