  • Page 5: Evaluation Kit Description

    The EVK-ELLA-W1 evaluation kits provide a simple way to evaluate the ELLA-W1 host-based multiradio modules with Wi-Fi and Bluetooth [2]. The EVK-ELLA-W1 evaluation board comes with on-board antennas for Wi-Fi and Bluetooth. External antennas can optionally be connected through U.FL coaxial connectors. The evaluation kit includes a standard full-size SDIO adapter board (compatible with host sockets designed for SD memory cards) for host communication.

  • Page 6: Kit Includes

    EVK-ELLA-W1 - User Guide 1.2 Kit includes The EVK-ELLA-W1 evaluation kit includes the following:  Evaluation board EVB-ELLA-W161 or EVB-ELLA-W163  SDIO adapter including flat ribbon cable  Quick Start card 1.3 Software and documentation The reference drivers for the ELLA-W1 module series are developed by Marvell and can be re-distributed by u-blox to customers free of charge after signing a license agreement [1].

    An example card reader for Linux is the “Sonnet SDXC UHS-I Pro Reader/Writer ExpressCard/34” [5]. Be careful while inserting the SDIO adapter of the EVK-ELLA-W1 into the SDIO slot of a laptop. Such built-in readers might be designed poorly and can be damaged easily compared to the ones found on development platforms, which are more compact.

    EVK-ELLA-W1 - User Guide Figure 7: Bluetooth protocol stack Another driver for Bluetooth is also available in the reference driver package, which is not bound to BlueZ, instead it exports a character device, which can be used by third-party user space Bluetooth stacks.

  • Page 14: Extracting Package Content

    EVK-ELLA-W1 - User Guide For older kernels (<3.2), use compat-wireless (now named backports) to provide recent versions of the kernel's 802.11 APIs to support all the driver features. In this case, cfg80211 has to be compiled as a module (CONFIG_CFG80211=m).
