Page 10: Introduction
Chapter 1 Introduction This chapter introduces the Juno ARM Development Platform (ADP). It contains the following sections: • 1.1 About the Juno ADP on page 1-11. • 1.2 Ports and I/O on page 1-12. • 1.3 Use of Ethernet ports on page 1-13. -
Page 11: About The Juno Adp
An architecture that is aligned with Level 1 of the Server Base System Architecture. • ARM big.LITTLE MP support. On Juno r1 only, the LITTLE cluster is limited to the lowest DVFS Operating Performance Point (OPP) due to hardware limitations. -

Figure 1-2 V2M-Juno motherboard rear panel The rear Ethernet port is not enabled in hardware on Juno r0. On Juno r1 and later, it is enabled and connected over the PCI Express bus. ARM DEN0928F Copyright © 2015 ARM. All rights reserved. 1-12 Non-Confidential... -
Page 13: Use Of Ethernet Ports
Port numbering in Linux and Android with U-boot If U-Boot is used, you must use the tool within Linux to set up an Ethernet port as follows: ifconfig ifconfig eth0 hw ether [MAC address] ARM DEN0928F Copyright © 2015 ARM. All rights reserved. 1-13 Non-Confidential... -

SoC UART0 On the back panel. Used by the boot firmware, for example the V2M-Juno motherboard, ARM Trusted Firmware, and UEFI. It also used by the Operating System, for example, the Linux kernel. -
Page 15: Monitor Compatibility
The Samsung SyncMaster SA850 is available for purchase at the time of writing and works well when using 1024×768 or half of the native resolution, but only if the following kernel command-line option is provided to force the resolution. ARM recommends adding this option to get the monitor to work: video=HDMI-A-1:1280x720@60 (If you have a 3.10 based kernel, then replace HDMI-A-1 with DVI-D-1) -

Page 26: Firmware Components
An alternative loader provided with certain pre-built Linaro image bundles that is used instead of UEFI. The implementation is based on U-Boot from DENX. Note ARM strongly recommends that you immediately upgrade to the latest available firmware before using the V2M-Juno motherboard. Related concepts 2.5 Board recovery procedure on page 2-22. - Page 27 Power domains within the SoC which are powered on. Boot protocol The SCP ROM firmware interacts with the ARM Trusted Firmware, which securely transfers the SCP RAM firmware image to the SCP at runtime. The SCP then passes control from the SCP ROM firmware to the SCP RAM firmware and the boot process continues.
- Page 28 Unified extensible Interface Firmware (UEFI) The Unified Extensible Firmware Interface (UEFI) is a boot firmware specification that the UEFI forum maintains and develops. ARM is a member of the UEFI forum and contributes to the UEFI ARM bindings. Linaro provides an AArch64 implementation of this specification for ADPs, based on the EFI Development Kit 2 (EDK2), available from Tianocore at http://www.tianocore.org.
