Preface

This RANA Board Hardware Manual describes the System on Module's design and functions. Precise specifications for the TI AM335x processor can be found in the processor datasheet and/or user's manual.

In this hardware manual and in the schematics, active low signals are denoted by a "/" preceding the signal name, for example: /RD. A "0" represents a logic-zero or low-level signal, while a "1" represents a logic one or high-level signal.

Declaration of Electro Magnetic Conformity of the PHYTEC RANA Board

PHYTEC System on Modules (SOMs) are designed for installation in electrical appliances or, combined with the PHYTEC Carrier Board, can be used as dedicated Evaluation

Boards (for use as a test and prototype platform for hardware/software development) in laboratory environments.

CAUTION:

PHYTEC products lacking protective enclosures are subject to damage by ESD and, hence, may only be unpacked, handled or operated in environments in which sufficient precautionary measures have been taken in respect to ESD-dangers. It is also necessary that only appropriately trained personnel (such as electricians, technicians and engineers) handle and/or operate these products. Moreover, PHYTEC products should not be operated without protection circuitry if connections to the product's pin header rows are longer than 3 m.

PHYTEC products fulfil the norms of the European Union's Directive for Electro Magnetic

Conformity only in accordance to the descriptions and rules of usage indicated in this hardware manual (particularly in respect to the pin header row connectors, power connector and serial interface to a host-PC).

Implementation of PHYTEC products into target devices, as well as user modifications and extensions of PHYTEC products, is subject to renewed establishment of conformity to, and certification of, Electro Magnetic Directives. Users should ensure conformance following any modifications to the products as well as implementation of the products into target systems.

The RANA Board is one of a series of PHYTEC System on Modules that can be populated with different controllers and, hence, offers various functions and configurations. PHYTEC supports a variety of 8/16 and 32-bit controllers in two ways:

1. As the basis for Rapid Development Kits which serve as a reference and

Evaluation platform.

2. As insert-ready, fully functional phyCORE OEM modules, which can be

© PHYTEC Embedded Pvt. Ltd 2013 7

Embedded directly into the user's peripheral hardware design.

Implementation of an OEM-able SOM subassembly as the "core" of your embedded design allows you to focus on hardware peripherals and firmware without expending resources to "re-invent" microcontroller circuitry. Furthermore, much of the value of the phyCORE module lies in its layout and test.

Production-ready Board Support Packages (BSPs) and Design Services for our hardware further reduce development time and expenses. Take advantage of PHYTEC products to shorten time-to-market, reduce development costs, and avoid substantial design issues and risks. For more information go to: http://www.phytec.in/services/hardware.html

subject to changes, due to ongoing part maintenance for our products.

1 Introduction

Figure 1- 1. RANA Board

The RANA Board for phyCORE-AM335x is a low-cost, feature-rich software development platform supporting the TI AM335x processor families. At the core of the RANA board is the PCL-051/phyCORE-AM335x System On Module (SOM) in a direct solder form factor, containing the AM335x processor, SDRAM, NAND Flash, power regulation, supervision, transceivers, and other core functions required to support the RANA AM335x Board.

Surrounding the SOM is the PBA-CD-03/RANA Carrier Board, adding power input, buttons, connectors, signal breakout amongst other things.

The PCL-051 System On Module is a connector-less, BGA style variant of the PCM-

051/phyCORE-AM335x SOM. Unlike traditional PHYTEC SOM products that support high density connectors, the PCL-051 SOM is directly soldered down to its Carrier Board using

PHYTEC's Direct Solder Connect technology. This solution offers an ultra-low cost Single

Board Computer for the AM335x processor, while maintaining most of the advantages of the SOM concept.

Adding the phyCORE-AM335x SOM into your own design is as simple as ordering the connectored version (PCM-051) and making use of our RANA Carrier Board (PBA-CD-03),

2 PCL-051/phyCORE-AM335x System on Module

This chapter gives a brief introduction to the PCL-051/phyCORE-AM335x System on

Module (SOM), highlighting its benefits and features. For more detailed information, please refer to the Hardware Manual for the modular, connectored version of the SOM (PCM-051) by clicking here .

The phyCORE-

AM335x belongs to PHYTEC’s phyCORE System on Module (SOM) family.

The phyCORE SOMs represent the continuous development of PHYTEC SOM technology. Like its mini-, micro-, and nano MODULE predecessors, the phyCORE boards integrate all core elements of a microcontroller system on a subminiature board and are designed in a manner that ensures their easy expansion and embedding in peripheral hardware developments.

As independent research indicates that approximately 70% of all EMI (Electro Magnetic

Interference) problems stem from insufficient supply voltage grounding of electronic components in high frequency environments, the phyCORE board design features an increased pin package. The increased pin package allows dedication of approximately

20% of all connector pins on the phyCORE boards to ground. This improves EMI and EMC characteristics and makes it easier to design complex applications meeting EMI and EMC guidelines using phyCORE boards even in high noise environments. phyCORE boards achieve their small size through modern SMD technology and multilayer design. In accordance with the complexity of the module, 0402-packaged SMD components and laser-drilled Microwave are used on the boards, providing phyCORE users with access to this cutting edge miniaturization technology for integration into their own design.

The PCM-051, connectored version of the phyCORE-AM335x is a sub-miniature (41 x 51 mm) insert-ready SOM populated with AM335x processor. Its universal design enables its insertion into a wide range of embedded applications. All processor signals and ports extend from the processor to high-density pitch (0.5 mm) connectors aligning two sides of the board. This allows the SOM to be plugged like a "big chip" into a target application.

The PCL-051, connector less version of the phyCORE-AM335x populating the RANA

Board is identical to the connectored version, with the exception of the connection interface. Instead of two high density connectors aligning the edges of the board, the PCL-

051 solders directly down to its Carrier Board with a BGA style footprint.

Precise specifications for the processor populating the board can be found in the applicable processor user's manual and datasheet. The descriptions in this manual are based on the AM335x processor. No description of compatible processor derivative

functions is included, as such functions are not relevant for the basic functioning of the

RANA Board.

3 Power

3.1 Wall Power (X2)

Wall power X2 provides the necessary board voltages.

A suitable +5V DC +- 5% / 1A or greater wall power adapter should be used with a center positive contact. An appropriate power supply can be ordered with the kit at the time you place your order.

CAUTION:

Do not use a laboratory adapter to supply power to the Carrier Board! Power spikes during power-on could destroy the phyCORE module mounted on the Carrier Board. Do not change jumper settings while the Carrier Board is supplied with power.

4 Ethernet (X17)

The 10/100 ETH0 interface, derived from the TI AM335x processor RMII1 signals, is accessible at an RJ-45 connector at X17.LEDs are integrated on the connector for indication of LINK (green) and SPEED (yellow).

The Ethernet PHY on the SOM supports the HP Auto-MDIX function, eliminating the need for considerations of a direct connect LAN cable or cross-over patch cable. The transceivers detect the TX and RX signals of the connected devices and automatically configure their RX and TX pins accordingly.

5 RS-232 Console (X7)

The RA ( Right Angle ) connector X7 provides connectivity to the RANA (UART) signals at

RS-232 level. This interface does not include the RANA UART0_RTS and UART0_CTS signals for flow control. This connection is provided primarily for console access, but could be reconfigured for other purposes if needed.

A standard straight-through serial cable connected to a PC is required to access this console port. This port has the benefit of providing access to Barebox and to early Linux boot log message, as opposed to the console access provided over the USB port, which provides neither. Use appropriate serial communications software such as minicom for

Linux, or putty for Windows. Configure the port for 115200,8,N,1 (8 data bits, no handshake, 1 stop bit). Below Table gives a detailed description of the signals at X8.

6 USB Connectivity

6.1 USB Host (X35)

The USB0 & USB1 interface signals are routed to the connector of X35 (Dual USB A-

Standard).The USB interface of the RANA processor complies with USB 2.0 HS specification and supports dual role device configuration, due to its USB-A style connector,

The USB interfaces on the RANA board are equipped with ESD protection. Both the interfaces are provided 5V supply that is current limited by U4 (TPS2051B). It supports connection of different USB devices such as mass storage device, keyboard, and mouse.

The USER can also have an OTG configuration for the both USB interfaces if required through the jumper X31.

7 SD Card (X12)

The RANA board provides a Micro SD card slot at X12 for connection to the RANA's

MMC0 interface. The interface is powered by an instant-on 3.3 V power supply and has card detect support (CDET) via the RANA processor X64.A18 signal.

In addition to mass storage usage, the processor can boot from this interface. As the default boot mode of the phyCORE-RANA SOM, SD boot is selected by closing 3+4 pins of JP5.

7.1 Inserting and Removing an SD Card

Insert a micro SD Card into slot X12, label up and pins facing down. After aligning the card with the connector, push to insert. The card will make a clicking sound and latch into the connector. To eject the card, push the card in to release. The connector will click and the card will be safe to remove. To avoid damaging the connector do not attempt to pull the card directly out without first pushing inward to release the lock mechanism.

8 System Reset Button (S4)

The RANA Board is equipped with a system reset button at S4. Pressing the button will toggle the nRESET_IN signal low and generate a manual system reset driving RESETn on the phyCORE-AM335x low.

The system reset signal, nRESET_IN, is available on the Expansion connector (see

Chapter 13 for more information) and can be used to reset various other peripheral devices. Refer to the PCM-051/phyCORE-AM335x Hardware Manual for details on the

RESETn signal.

CAUTION:

When running Linux a proper system shutdown should be performed, or reboot executed instead of pressing the reset button. Pressing the reset button (or cutting power) without properly shutting down can cause file system errors and is not advised. Issue a poweroff or reboot command at the Linux prompt to avoid file system damage. Only use the reset button when not running Linux, or if the system freezes up.

9 Board Power LED

’s

The RANA board is populated with two Power LED’s D6 & D10 with VCC5V and VCC3V3 respectively to ensure the proper supplies on board.

10 Boot Selection (JP5)

Jumper JP5 provides a way to override the default boot option configured on the RANA

SOM.

Figure 10- 1. Jumper Numbering Scheme

Figure 10-1 shows the jumper pin numbering scheme. Pin 1 on the board is marked with a cut in rectangle on the PCB silk screen. It is also visibly marked with a clipped corner on the component outline.

Table 10-1 shows the required jumper positions for configuring the desired boot device.

Use jumper wires to connect the pins of JP5 based on the settings described.

By default JP5 is open, configuring the RANA for NAND boot.

11 Real-Time Clock Options (RTC)

There are three options for an RTC on the RANA-AM335x.

11.1 PMIC RTC

The Power Management IC at U4 includes an integrated RTC. This RTC includes alarm and time keeping functions. The RTC is supplied by the main system power when it is on, and by the backup battery voltage VBAT_IN_4RTC, if present, when the main system power is off and the jumper J10 has been moved from its default position of (1+2) to position (2+3).

11.2 AM335x RTC

The AM335x processor also includes an integrated RTC. However, the RTC integrated in the AM335x uses significantly more power than the RTC in the PMIC. Because of this power disadvantage, the SOM has not been designed to support the AM335x RTC with backup power.

11.3 External RTC

The AM335x processor SOM also includes External RTC IC (RV-4162-C7). This RTC is

Provided with External battery Backup and also given option for the USER to place own battery at JP4.

12 JTAG

The JTAG edge card connector X3 provides an easy means of debugging the phyCORE

AM335x in your target system via an external JTAG probe.

Note:

The JTAG connector X3 only populated with the order. All JTAG signals are accessible from the carrier board. See Below mentioned table for details on the JTAG signal Pin assignment.

13 Expansion Connectors (X19, X20)

Two 2x30 2mm Expansion connectors (X19 and X20) provide easy access to many of the phyCORE-AM335x signals. All processor signals on the Expansion connector are 3.3 V. As an accessory, add-on expansion boards such as LCD and WiFi are made available through PHYTEC to connect to the Expansion connectors.

Most of the signals routed to the expansion connector have been configured for a given pin muxed function. Using these signals are alternate functions requires BSP modifications.

Tables detailing signal mapping of the Expansion Connectors are provided below. These tables list only the primary function intended on the RANA Board, but can be reconfigured for many other purposes. Refer to the AM335x Technical Reference manual on available operation modes.

Table 13- 11. Ethernet (RGMII) Signal Map

The AM335x Ethernet2 interface signals can connect to any industry-standard Ethernet transceiver or they can be used for other purposes. The AM335x processor supports MII, RMII and

RGMII modes on this interface. It does not support GMII mode. It is strongly recommended to place the Ethernet PHY on the Carrier Board close to the pins of the SOM's Ethernet interface to achieve a trace length of less than 100 mm. The Ethernet2 interface signals are available on the

Rana-AM335x connector on the pins listed in the below Table
