This page collects information about's TI AM335x ARM-based BeagleBone board.



The BeagleBone is a low-cost, high-expansion BeagleBoard using the TI AM3358/9 SoC based on an ARM Cortex-A8 processor core using the ARMv7-A architecture. It is similar to the earlier BeagleBoards and can act as a USB or Ethernet connected expansion companion for your current BeagleBoard and BeagleBoard-xM or work stand-alone. The BeagleBone is small even by BeagleBoard standards yet still provides much of the performance and capabilities of the larger BeagleBoards.

BeagleBone ships with a 4GB micro-SD card preloaded with the Angstrom ARM Linux distribution.

The board uses a TI TPS65217B PMIC to generate stable supply voltages regardless of input power variation. +5V DC power can be supplied to the BeagleBone through a barrel connector or from the mini-USB, both of which are located near the large RJ45 Ethernet connector.

The mini-USB type-A OTG/device socket is multi-functional. In addition to providing an alternative source of power, it gives access to a front-end two-port USB client-side hub (not related to the separate host-mode USB type A socket on the other end of the board). One port of this hub goes directly to the TI AM3358/9 SoC, while the other port connects to a dual-port FT2232H USB-to-serial converter to provide board-to-host serial communications (Linux console by default) and/or JTAG debugging. The BeagleBone's Linux console is available through this USB serial connection.

The SoC USB connection to the front-end hub works in one of two modes which can be toggled at will at any time: it either presents the SD card as a mountable USB storage device to the host, or it provides an Ethernet-over-USB networking interface which yields a simple method of quick-start. The Ethernet-over-USB facility is additional to the BeagleBone's normal 10/100 Ethernet interface, which is directly implemented in the SoC rather than hanging off USB as in some other designs. Full IPv4 and IPv6 networking is provided by the supplied Linux system out of the box.

Development environments

Instead of just using compiler + editor, you can use complete image create "development tool chains" which integrate compiler, build system, packaging tools etc. in one tool chain.
