WARNING!

ESD-Sensitive Electronic Equipment

Observe ESD-safe handling procedures when working with this product. Always use this product in a properly grounded work area and wear appropriate ESD-preventive clothing and/or accessories. Always store this product in ESD-protective packaging when not in use.

1 Important Safe Handling Information

Safe Handling Precautions

The Eagle baseboard contains a high number of I/O connectors with connection to sensitive electronic components. This creates many opportunities for accidental damage during handling, installation and connection to other equipment. The list here describes common causes of failure found on boards returned to Diamond Systems for repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any vendor’s) embedded computer boards. ESD damage – This type of damage is usually almost impossible to detect, because there is no visual sign of failure or damage. The symptom is that the board eventually simply stops working, because some component becomes defective. Usually the failure can be identified and the chip can be replaced. To prevent ESD damage, always follow proper ESD-prevention practices when handling computer boards. Damage during handling or storage – On some boards we have noticed physical damage from mishandling. A common observation is that a screwdriver slipped while installing the board, causing a gouge in the PCB surface and cutting signal traces or damaging components. Another common observation is damaged board corners, indicating the board was dropped. This may or may not cause damage to the circuitry, depending on what is near the corner. Most of our boards are designed with at least 25 mils clearance between the board edge and any component pad, and ground / power planes are at least 20 mils from the edge to avoid possible shorting from this type of damage. However, these design rules are not sufficient to prevent damage in all situations. A third cause of failure is when a metal screwdriver tip slips, or a screw drops onto the board while it is powered on, causing a short between a power pin and a signal pin on a component. This can cause overvoltage / power supply problems described below. To avoid this type of failure, only perform assembly operations when the system is powered off. Sometimes boards are stored in racks with slots that grip the edge of the board. This is a common practice for board manufacturers. However, our boards are generally very dense, and if the board has components very close to the board edge, they can be damaged or even knocked off the board when the board tilts back in the rack. Diamond recommends that all our boards be stored only in individual ESD-safe packaging. If multiple boards are stored together, they should be contained in bins with dividers between boards. Do not pile boards on top of each other or cram too many boards into a small location. This can cause damage to connector pins or fragile components. Power supply wired backwards – Our power supplies and boards are not designed to withstand a reverse power supply connection. This will destroy each IC that is connected to the power supply (i.e. almost all ICs). In this case the board will most likely will be unrepairable and must be replaced. A chip destroyed by reverse power or by excessive power will often have a visible hole on the top or show some deformation on the top surface due to vaporization inside the package. Check twice before applying power! Bent connector pins – This type of problem is often only a cosmetic issue and is easily fixed by bending the pins back to their proper shape one at a time with needle-nose pliers. The most common cause of bent connector pins is when a PC/104 board is pulled off the stack by rocking it back and forth left to right, from one end of the

connector to the other. As the board is rocked back and forth it pulls out suddenly, and the pins at the end get bent significantly. The same situation can occur when pulling a ribbon cable off of a pin header. If the pins are

Page 5

bent too severely, bending them back can cause them to weaken unacceptably or even break, and the connector must be replaced.

Jumper block JP1 configures the voltage supply for the LVDS backlight and for LVDS VDD as well. The orientation of the block in the diagrams matches the orientation of the jumper block when the board is rotated so that the Apalis module is on the Top edge. Available options for Back light are +5V and +12V. +12V is not used by any circuit on the Eagle. +12V is needed for the LCD backlight, and the backlight is to be powered via the backlight power connector J10, hence +12V is supplied on the main power input connector along with +VIN. By default LVDS backlight is provided with +12V and the LVDS VDD is provided with 3.3V. Figure 11 shows the default jumper locations.

10 Start-up scripts

Start-up script [custom_startup_script.sh] is added along with the image. Start-up script exports the GPIO’s It helps to configure Default states for I2C GPIOs. Start-up configuration script can be found in /etc/init.d/.

Default states for GPIOs available in J24 and J25 are configured using gpioconfig.xml file gpio-number – gpio number to configure dir - direction, in or out val - value, high or low Refer section 13.4.3 for default GPIO states configured in the release image.

Configure the display interface through U-boot video arguments (Detailed Instruction available in the Toradex links).

Below are some video arguments tested for I.MX6 COM during development for each display interface

For VGA Interface: setenv vidargs 'video=mxcfb0:dev=vdac,1024x768M@50,if=RGB565 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M'

For HDMI Interface: setenv vidargs ‘video=mxcfb0:dev=hdmi,1920x1080M@50,if=RGB24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M’

For LVDS Interface:

setenv vidargs ‘video=mxcfb0:dev=ldb,1920x1080M@50,if=RGB24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M’

11 Display Features

Eagle and Eaglet supports HDMI, VGA and LVDS LCD as display device options.

11.1 VGA

VGA display can be set as primary or secondary Display using the “setenv vidargs” command during boot stage. Maximum VGA resolution is 1280x1024 @ 60Hz. VGA display is supported only in Apalis iMX6. Apalis T30 and TK1 module does not support VGA display output.

For quick reference user may refer the above section ‘some video argument tested for I.MX6 COM during development” for Uboot commands. User has to edit the resolution value ‘XXXX x XXXXM@50’ in the arguments

according to display available with them.

For other Apalis COM modules to enter the arguments refer the above Toradex developer link by clicking on ‘setenv vidargs’.

LVDS display is supported for all the three Apalis modules. Maximum resolution supported by different Apalis modules are as below.

To set Backlight brightness when using LVDS display:

For I.MX6 COM module:

Note:

Internal to the T30 module, it serializes the parallel RGB and control signals into differential LVDS pairs.

Additional internal GPIOs need to be controlled for setting up the LVDS display when using T30 ARM module. Refer Section 5.5.2 of T30 datasheet for information.

GPIO_480 controls the 5V/3V Power enable for LVDS display and it should be enabled for LVDS interface

functionality. GPIO_480 is enabled by default through the startup scripts. Refer GPIO Handling section for more information.

Make sure 12V power input is fed to Eaglet/Eagle at J7. (Connect 12V at J1 on Panel IO, if used) While connecting LVDS display using T30 module, if any screen brightness problem (Dim display) is

encountered, make sure the following GPIO’s configuration is proper. GPIO No 219, GPIO No 223 should drive logic low state. Refer the link

http://developer.toradex.com/knowledge-base/gpio-(linux) for processor GPIO read/write procedure.

11.3.1 LCD Backlight

The LCD backlight control is provided by a PWM circuit. LCD backlight power and control are on a separate latching connector (J10). Duty cycle (Brightness) can be varied as instructed in the link below

http://developer.toradex.com/knowledge-base/backlight-(linux)

Refer LVDS VCC & Backlight (JP1) section for jumper configuration details.

11.4 Dual Display

Eagle supports dual display operation i.e.; Multiple displays can be enabled at the same time based on the ARM module support. This feature can be enabled by setting the environment variables during boot stage. Display can be either extended or duplicated to secondary display. In T30, dual display can be configured using the options available in Monitor preferences In iMx6, extended display can be achieved using applications like Cairo to load data on the secondary frame buffer. Note: In Extended display mode the total resolution of the combined displays should not exceed the maximum resolution supported by the processor

Sample test set up for demonstrating dual display with iMx6:

Dual display feature can be demonstrated using the Cairo Library. Copy the Cairo & sample *.png image to the target device and enter the following command.

Sample image will be displayed on the secondary display. NOTE: Before running cairo utility user has to set the appropriate video arguments. For example, to test dual display on VGA and HDMI set the following video argument in Uboot

Note: U boot arguments set manually from U boot prompt may be modified by start-upcscripts at boot time. So if someone wants to set these extra u boot parameters permanently, then disable start up scripts.

12 Serial Ports and System Console

12.1 Configuration

Eaglet support 4 serial ports (Serial ports 1 to 4) and Eagle supports up to 8 serial ports (Serial ports 1 to 8). Serial ports 5 to 8 are realized using PCIe to UART chip. For Eaglet, serial ports 1 and 2 supports RS232/422/485 modes and serial ports 3 and 4 supports only RS232 mode. For Eagle, all the serial ports (1-8) supports RS232/422/485 modes. Mode selection is handled by I2C GPIO expander and all the ports are set in RS232 mode by default. Refer GPIO Handling section for more information. Serial port multimode functionalities are ARM module dependent due to hardware limitations in the ARM modules. Below tables illustrates the available Serial modes for each ARM module in Eagle.

Configuring Serial ports:

Serial Port configuration includes two steps: Step 1: Configure the mode – RS232/RS422/RS485.

Mode configuration can be done using I2C GPIOs. Refer section 12.4 for mode configuration details. Refer GPIO Handling section for configuring GPIO states Note: By default, all serial ports are configured for RS232 mode through startup scripts

Step 2: Enable RS485 direction control feature if port is configured for RS422 or RS485 mode.

When the port is used in RS422 and RS485 mode, this RS485 direction control utility should be enabled to control driver enable (DE) and Receiver enable (RE#) of the transceiver chip. Note: When the serial port is in RS232 mode, RS485 direction control utility should be disabled to ensure RS232 flow control signals operation (RTS, CTS).

www.diamondsystems.com Eagle User Manual Rev 1.4 Page 55

Page 56

Syntax:

# rs485_util<space><port_number><space><1/0>

Example-1: Enable ttymxc0 for RS485/RS422

# rs485_util ttymxc0 1

Example-2: Disable ttymxc0 for RS485/RS422

# rs485_util ttymxc0 0

Enabling/Disabling RS485/RS422 direction control utility:

RS485_util gives the option to enable disable RS485/422 direction control on Apalis and Exar UART ports.

RS485 Direction control scheme:

Figure 14 RS-485 direction control hardware implementation

Above figure describes the RS485 direction control implementation in Eagle. When Port is configured in RS485 mode, both DE and RE# are control by RTS signal. When Port is configured in RS422 mode, DE is controlled by RTS and RE# is pulled down (enabled) independent of RTS. In RS485 mode, RS485 direction control utility toggles the RTS line while sending data to enable/disable DE and RE# controls for half duplex communication. In RS422 mode, although the Receiver is always enabled by pull down, RS485 direction control utility should be enabled for controlling the driver enable (DE). Note: Due to limitation in T30 ARM module, RTS toggling is not possible in RS485 mode and the RTS line is driven high always by the RS485 direction control utility to ensure transmission. Data reception is not possible in Apalis UARTs (Port 1-4) in RS485 mode with T30 ARM module.

In both Eaglet and Eagle baseboard, serial port 1 acts as a console port (J11). For using port 1 as a normal Serial port, the debug console functionality should be disabled by following the instruction given below

Power on and Interrupt the Uboot in the debug console. Type setenv console ‘’ and Enter. This sets the default debug console as none. Type saveenv, press Enter key. Type reset, press Enter. This will reboot the board and it’s ready to go.

Figure 15 Screen shot – Configuring the Console debug port

Same procedure can be used to set port 1 as debug console again.

12.3 Serial port numbers

For Exar ports (Port 5 to 8), without any external serial device connected to the board, the device number detected are as follows

Refer http://developer.toradex.com/knowledge-base/uart-(linux) for additional information on UARTs.

Note:

1. Device name for EXAR Serial ports varies when some add on cards with serial devices are connected to

the module.

2. These EXAR Serial ports functionality is not supported in current software version release.

15 Type-specific I/O Expansion

The Apalis form factor designates a group of pins on the connector for signals that vary from module to module. This enables the Apalis form factor to accommodate new features on new processors that were not available on prior modules or accounted for in the common module pinout. These signals are brought out to a connector J27 on the Eagle full-size board to give the user access to them. A custom daughterboard may be installed on J27 and fixed in place using the mounting hole provided on the board. The pinout of this connector is shown on page xxx. The definitions of the type specific pins for each module may be found in that module’s user manual. Board connector: Mating connector for daughterboard: Type specific daughterboard mechanical dimensions:

16 Programming I2C

Apalis modules support 3 I2C master interfaces. The following table provides details about the various devices available on the Eagle and Eaglet baseboard.

Please refer to http://developer.toradex.com/knowledge-base/i2c-(linux) for more details on I2C handling for Apalis.

17 Factory reset and Recovering MAC address

Eagle module has two Ethernet interfaces, one directly from the ARM module and the other through i210 Ethernet controller. The first Ethernet interface from ARM modules carries the unique MAC address given by Toradex. MAC address for the second port are programmed during manufacturing test through U Boot argument.

If a reset of U boot arguments happens, all arguments modified over time will be lost and default arguments as shipped from Toradex will be present. Meaning, the MAC address for the second Ethernet port on the carrier card also will be lost. In such a case, user can check for MAC address present on the product sticker and recover it by entering the same in U boot arguments.

18 Panel IO

Eagle and Eaglet supports an add-on board, which connects to the headers available on the bottom edge of the board (orientation with Apalis module on Top edge.). Panel IO board supports the standard connectors for the following interfaces terminated at dual row 2mm header on Eagle/Eaglet baseboard.

19 CAN Add-on Module

Eagle and Eaglet supports 2x CAN ports realized by mounting a CAN Mezzanine module on 2x10 header (J14). 2x CAN interface from Apalis module is directly routed to 20 pin Header on Eaglet/Eagle baseboard, along with 1x I2C and 1XSPI interface for general use. CAN transceivers are available on the CAN Add-on module. Below block diagram provides the details about the CAN add-on module.

20.2.1 Assembly procedure

The following procedure demonstrates how to attach the Apalis heatsink to the Apalis module to complete the heatsink solution. Please read the procedure very carefully to ensure that the module does not get damaged. Necessary precautions should be taken to avoid the electrostatic charges.

1. Clean the processor’s top surface using an anti-static cloth.

2. Insert the Apalis module in the MXM socket X1 on the Apalis carrier board.

3. Carefully remove the plastic foil from the TIM.

4. Carefully align the mounting holes {1}, {2}, {3}, and {4} on the heatsink to be in-line with fasteners

available on the Apalis carrier board. Place the heatsink on the system.
