AIC3262/Firmware Release Notes

=Introduction=

You should have received a firmware tools and build package as part of the release of the AIC3262 driver for OMAP4. This package is named: mkcfw_r._.zip

This package contains pre-built firmware image for the AIC3262. This document explains the steps needed to customize and rebuild the firmware should your application require it.

=Pre-requisites=

1. PurePath Studio GDE (PPS-GDE) version 5.95 Revision 17483 or later. Please see. You will be required to create an account with TI (unless you already have one) before making a request. Please ensure that you use your corporate email address when creating your account. This allows us to quickly determine the request is legit and will result in you being provided access quickly.

2. Windows XP/Windows 7 PC

3. Access to an AIC3262 EVM (such as ) is helpful, but not required

= Installation =

Install PPS-GDE using the installer you obtained from TI. Please uninstall any older version ppresent on your PC before installing a newer version.

Unzip the firmware tools and build package to a location your choice (we'll call it FW_TOOLS_PATH\)

Install the UserComponentLibrary/ found in the release under %USERPROFILE%\My Documents\Texas Instruments Inc\PurePathStudio (Portable Audio) MiniDSP 5.95\UserComponentLibrary\

= Build Instructions =

First, open the process flow(s) of interest and modify it according to your application needs. You may use an EVM to verify changes you make (please see appropriate user documentation on usage of EVM adn PPS-GDE). Once you are satisfied with your changes, rebuild the process flow.

Open a DOS CMD window and navigate to FW_TOOLS_PATH\

C:\> cd FW_TOOLS_PATH\

Now, run mkcfw_win.exe in the following manner:

FW_TOOLS_PATH> mkcfw_win ./firmware/build/tlv320aic3262_fw_v1.cfw tlv320aic3262_fw_v1.bin

Push tlv320aic3262_fw_v1.bin to the /vendor/firmware</tt> directory and reboot (the example below used ADB. You may use whatever other method that lets you trasfer binary files between your PC and the target filesystem:

FW_TOOLS_PATH> adb push tlv320aic3262_fw_v1.bin /vendor/firmware FW_TOOLS_PATH> adb reboot

The device driver will now read your new firmware and download the process flows as appropriate from it.

Please refer to the README in teh firmware tools package for additional help on running mkcfw_win.exe</tt>
