=Build Instructions=

Android File System
This section explains how to patch and build the Android File System Unzip Blaze_AIC_AIC3262_sw_release3_Audio_HAL.zip into a temporary directory. $cd mydroid/device/ti/common-open/ patch -p1 < {temporary directory}/Blaze_AIC_AIC3262_sw_release3_Audio_HAL/Blaze_aic3262_audio_hal_sw_release3.patch

Compiling the audio module

$cd mydroid mydroid$source ./build/envsetup.sh mydroid$lunch full_blaze-userdebug mydroid$make clean-audio.primary.blaze mydroid$make audio.primary.blaze for blaze_aic_tablet2 mydroid$make clean-audio.primary.blaze_tablet mydroid$make audio.primary.blaze_tablet

The above steps will create audio.primary.blaze.so (for blaze_aic) and audio.primary.blaze_tablet.so (for blaze_aic_tablet2) Push the .so file in to target as follows ./adb push audio.primary.blaze.so /system/lib/hw/ (for blaze_aic) ./adb push audio.primary.blaze_tablet.so /system/lib/hw/ (for blaze_aic_tablet2)

Tinymix control string enabling

This section explains how to patch and build the tinymix Unzip Blaze_AIC_AIC3262_sw_release3_Audio_HAL.zip into a temporary directory. $cd mydroid/external/tinyalsa/ patch -p1 < {temporary directory}/Blaze_AIC_AIC3262_sw_release3_Audio_HAL/Blaze_aic3262_tinymix_control_sw_release3.patch $cd mydroid make tinymix push through adb in to the target as follows ./adb push tinymix /system/bin/

Follow the build instructions given here: http://omappedia.org/wiki/L27.IS.2.M1_OMAP4_Icecream_Sandwich_Release_Notes#Building_Android_Filesystem_.28AFS.29_with_TI_Codecs_enabled under http://omappedia.org/wiki/L27.IS.2.M1_OMAP4_Icecream_Sandwich_Release_Notes#Build_Instructions

DSP firmware loading
The DSP firmware file (tlv320aic3262_fw_v1.bin file) need to be loaded to the target as follows ./adb push tlv320aic3262_fw_v1.bin /vendor/firmware/ ./adb reboot

The firmware consists of modes and configurations. The tinymix command "FIRMWARE SET MODE" sets the required mode and configurations to be used. The value is "{mode_number}<<8|{cfg_number}".

Example firmware binary

tinyalsa utils
Build the tinyalsa utils. These utilities are needed for playback and recording wav files. cd  mydroid make tinycap make tinyplay make tinymix

Kernel
This section explains how to patch and build the kernel Unzip Blaze_AIC_AIC3262_sw_release3_kernel.zip into a temporary directory. cd kernel/android-3.0 patch -p1 < {temporary directory}/Blaze_AIC_AIC3262_sw_release3_kernel.patch Follow the build instructions given here:http://omappedia.org/wiki/L27.IS.2.M1_OMAP4_Icecream_Sandwich_Release_Notes#Building_Kernel under http://omappedia.org/wiki/L27.IS.2.M1_OMAP4_Icecream_Sandwich_Release_Notes#Build_Instructions
