Important Note:

The design and software discussed on this site is available for download, but is no longer being actively developed and maintained. This wiki is in maintenance mode and the software is supported on Sitara E2E forum


General Platform Description[edit]

The development platform is primarily based on the AM1808 kit by Mistral. An extension card provided by Mistral serves as a wireless connectivity add-on.

Key Properties
  • Platform combines a AM1808 and a WL1271 connectivity solution
  • AM1808 are key catalog applications processor platforms, supported worldwide by TI Sales
  • Wireless Connectivity Card which incorporates a WiLink 6 based module
  • Supported Technologies: WLAN and Bluetooth support
  • Supported OS: Linux

General HW Description and Block Diagram[edit]

The WL1271 connectivity solution is available in the form of a daughter board.This board connects to the AM1808 board. This board will be interfaced to the EVM through the Expansion connectors J29 and J30. Generally the daughter board is plugged to the connector J29 of the AM1808 EVM and the BT signals are connected using the FRC cable. The daughter board uses 5V power available on the EVM to generate the required VBAT (3.6V) and VIO (1.8V) for the WL1271 module.

Connectivity Expansion Card Description[edit]

This daughter board contains an LSR module which is based on a WL1271 Wireless LAN and a Bluetooth combo chip.

The wireless LAN and Bluetooth  share one antenna which is mounted directly on the connectivity board.



1271 Connectivity Expansion Card Pin Assignment[edit]

The following table shows the pin assignment from the connectivity expansion card to the Main EVM:
