    HDMI Access to the HDMI interface is through the HDMI connector that is located on the bottom side of the board as shown in Figure 57 below. Figure 57 HDMI Connector The connector is microHDMI connector. This was done due to the space limitations we had in finding a place to fit the connector.

The microSD card is not supplied with the board. microSD Connector Figure 59 microSD Connector When plugging in the SD card, the writing on the card should be up. Align the card with the connector and push to insert.

    Cape Board Support The element14 BeagleBone Black Industrial has the ability to accept up to four expansion boards or capes that can be stacked onto the expansion headers. The word cape comes from the shape of the board as it is fitted around the Ethernet connector on the main board.

  • Page 90: Element14 Beaglebone Black Industrial Cape Compatibility

    BeagleBone Black Industrial Cape Compatibility The main expansion headers are the same between the BeagleBone and element14 BeagleBone Black. While the pins are the same, some of these pins are now used on the element14 BeagleBone Black. The following sections discuss these pins.

    SW using the I2C0 interface. 8.1.2 eMMC Pins The element14 BeagleBone Black Industrial uses 10 pins to connect to the processor that also connect to the P8 expansion connector. These signals are listed below in Table 15. The proper mode is MODE2.

    On power up, the eMMC is NOT reset. If you hold the Boot button down, this will force a boot from the microSD. This is not convenient when a cape is plugged into the board. There are two solutions to this issue: 1.

    Figure 61 Expansion Board EEPROM Without Write Protect The addressing of this device requires two bytes for the address which is not used on smaller size EEPROMs, which only require only one byte. Other compatible devices may be used as well. Make sure the device you select supports 16 bit addressing. The part package used is at the discretion of the cape designer.

    The I2C signals require pullup resistors. Each board must have a 5.6K resistor on these signals. With four capes installed this will be an effective resistance of 1.4K if all capes were installed and all the resistors used were exactly 5.6K. As more capes are added the resistance is reduced to overcome capacitance added to the signals.

    If you plan to use any of these signals, then on power up, these pins should not be driven. If you do, it can affect the boot mode of the processor and could keep the processor from booting or working correctly. If you are designing a cape that is intended to be used as a boot source, such as a NAND board, then you should drive the pins to reconfigure the boot mode, but only at reset.

    It should be noted, that the longer the pin and the further it is inserted into the element14 BeagleBone Black Industrial connector, the harder it will be to remove due to the tension on 92 pins. This can be minimized by using shorter pins or removing those pins that are not used by your particular design.

    It should be noted, that the longer the pin and the further it is inserted into the element14 BeagleBone Black Industrial connector, the harder it will be to remove due to the tension on 92 pins. This can be minimized by using shorter pins. There are most likely other suppliers out there that will work for this connector as well.

    This section will attempt to describe the tradeoffs and things to consider when selecting a connector and its pin length. 8.4.5 element14 BeagleBone Black Industrial Female Connectors Figure 69 shows the key measurements used in calculating how much the pin extends past the contact point on the connector, what we call overhang.

  • Page 104: Signal Usage

    Figure 69 Connector Pin Insertion Depth To calculate the amount of the pin that extends past the Point of Contact, use the following formula: Overhang=Total Pin Length- PCB thickness (.062) - contact point (.079) The longer the pin extends past the contact point, the more force it will take to insert and remove the board.

  • Page 106: Cape Power

    SYS_5V 250mA The VDD_3V3B rail is supplied by the LDO on the element14 BeagleBone Black Industrial and is the primary power rail for expansion boards. If the power requirement for the capes exceeds the current rating, then locally generated voltage rail can be used. It is recommended that this rail be used to power any buffers or level translators that may be used.

    5) If you are applying signals from other boards into the expansion headers, make sure you power the board up after you power up the element14 BeagleBone Black Industrial or make the connections after power is applied on both boards.

    BeagleBone Black Industrial and why they are different. This is a result of having the BeagleBone fit into the Altoids style tin. It is not required that the cape be exactly like the element14 BeagleBone Black Industrial board in this respect.
  • Page 109 There are numerous enclosures being created in all different sizes and styles. The mechanical design of these enclosures is not being defined by this specification. The ability of these designs to handle all shapes and sizes of capes, especially when you consider up to four can be mounted with all sorts of interface connectors, it is difficult to define a standard enclosure that will handle all capes already made and those yet to be defined.

    11.4 Trouble Shooting HDMI Issues Many people are having issues with getting HDMI to work on their TV/Display. Unfortunately, we do not have the resources to buy all the TVs and Monitors on the market today nor go to Ebay and buy all of the TVs and monitors made over the last five years to thoroughly test each and every one.
  • Page 118 11.4.3 OUT OF SEQUENCE Sometimes the display and the board can get confused. One way to prevent this is after everything is cabled up and running, you can power cycle the display, with the board still running. You can also try resetting the board and let it reboot to resync with the TV. 11.4.4 OVERSCAN Some displays use what is called overscan.
