    1 Murata Wi-Fi/BT EVK for i.MX6 1.1 Murata Kit Contents The Murata Kit includes all hardware necessary to bring up Wi-Fi/Bluetooth on Freescale i.MX6 Platforms. See Table 1. Each color-coded bag contains a separate component. Table 1: i.MX6 Kit Contents...

  • Page 8: Murata Modules Supported

    (Versions 1.0 & 2.0). Two InterConnect adapters are included to provide maximum flexibility for user to connect hardware easily to Freescale i.MX6 Platforms. The Murata Hardware Solution is outlined in Table 2: Murata Wi-Fi/Bluetooth EVB’s. Two of the EVB’s only support Wi-Fi (SN8000 and 1FX). All other EVB’s are Wi-Fi/Bluetooth combo solutions.

  • Page 9: I.mx6 Mpu Interfaces Supported

    TX/RX. Maximum Bluetooth UART rate (for Broadcom-based Murata modules) is 4 Mbps; typically set to 3 Mbps. Default initialization rate is 115200 Baud. Murata i.MX InterConnect Ver 1.0 uses additional pins on EMMC/MMC Plus footprint (SD_DATA4..7) to provide UART connection in some instances.

    Reference Platforms and which Murata Wi-Fi/BT kits (specifying Adapter Version) can be connected with them. Note that no third-party Freescale i.MX6 EVK’s are supported. For more information on a given Freescale i.MX6 Platform or Murata module, clicking on the hyperlink will navigate you to the relevant web page.

    Murata’s custom i.MX InterConnect Adapter. Given the differences in Freescale i.MX6 Platforms, two versions of the adapter are made available in each kit. Figure 2 and Figure 3 show Murata i.MX InterConnect Ver 1.0 & Ver 2.0 adapters plugged into the i.MX 6SoloX SABRE-SD.

  • Page 12: Version 1.0 Adapter Board

    2.1 Version 1.0 Adapter Board 2.1.1 Overview Figure 4 shows the top view of the Murata i.MX InterConnect Ver 1.0 Adapter. The adapter was designed to make use of Freescale EMMC/”MMC Plus” SD card connector footprint: in addition to SDIO _DATA0..3; there are four extra pads that bring out SDIO_DATA4..7 lines. The SDIO_DATA0..3 lines support 4-bit SDIO for WLAN.

Murata Wi-Fi/BT EVK is configured to draw power from Freescale Platform via “VDD” pin on SD card slot. WLAN SDIO is always default (no selection here) and Bluetooth UART is configured via SD_DATA4..7 lines.

  • Page 17: Wi-Fi Wl_Reg_On Option

    WL_REG_ON is controlled dynamically by the Freescale i.MX6 MPU. 2.1.3.1 Dynamic WL_REG_ON: First Approach The First Approach is to make use of “short pad” MUXing on the Murata Adapter board. Refer to Table 5 for necessary modifications. Note that once BT_UART_RTS is disconnected, then the Bluetooth UART connection will not work (Exception: Very slow UART rate of 115200 baud works without flow control).

    Figure 31 shows Murata Type 1DX Kit plugged into Freescale i.MX 6Quad SABRE-SD using Version 2.0 Adapter. Main problem here (as can be seen) is the inverted position of Murata EVK. This would make it very hard to probe test points on the hardware. One approach to solve this issue would be to get taller standoffs for the SABRE-SD and flip main board upside down.
