Software environment and development tools

CORE-A20 can support Linux&Android system. we provide the follow info:

Linux&Debian:

• It is possible to develop in almost any language using differents tools. In the developers page we illustrate some different development methods available and examples to manage the embedded peripherals in C or java languages.
• The C compiler and the Python interpreter are pre-installed by default. Also a small web server (Lighttpd) and PHP language interpreter is already available for the web development.
• Visit the developers index page...
• Other languages, tools, web servers, etc are available from Debian binary repositories and can be installed in few minutes.
• We propose, by default, a Debian Linux bootable from SD card. Ready to use SD cards are available on our eShop but any executable can be built starting from sources and following our tutorials. The basic requirements are a Linux Ubuntu PC.
