Express Juno r2 Development Platform
The Juno r2 Development Platform, that is, the V2M-Juno r2 motherboard, is a development
motherboard that provides access to the Juno r2 ARM Development Platform SoC. This is a
development chip that supports ARMv8-A software tooling, evaluation, and development.
The V2M-Juno r2 motherboard provides the following:
Juno r2 ARM Development Platform SoC (Juno r2 SoC)
The Juno r2 SoC provides a fully coherent dual-core Cortex
®
-A72 cluster, a fully coherent
quad-core Cortex-A53 cluster, and an I/O-coherent Mali
™
-T624 quad-core GPU cluster.
Dual-core Cortex-A72 cluster:
2MB L2 cache.

Scaling
(DVFS) of the Cortex-A72 and Cortex-A53 clusters, and the Mali-T624 GPU cluster.
Note
See the
Juno ARM

Development Platform SoC Technical Reference Manual (Revision r2p0)
for
more information on the Juno r2 SoC.
LogicTile site
The V2M-Juno r2 motherboard provides two headers that enable you to fit a Versatile Express
LogicTile daughterboard. A Thin Links TLX-400 Network Interconnect connects the
motherboard and daughterboard.
Powerup and configuration system
An on-board EEPROM stores board and file identification information and a microSD card
stores software images and configuration files. You can access the microSD card to perform
configuration file editing and to update software images.
Configuration of the V2M-Juno r2 motherboard and the LogicTile daughterboard, if fitted,
proceeds automatically under the control of the
Motherboard Configuration Controller
(MCC)
after powerup or reset.
You can customize the clock speeds and other configuration settings.
