Adding a new board or platform to android source and build

1. add a file AndroidProducts.mk

In the products directory, create an AndroidProducts.mk file that point to (and is responsible for finding) the individual product make files.

#

# This file should set PRODUCT_MAKEFILES to a list of product makefiles

# to expose to the build system. LOCAL_DIR will already be set to

# the directory containing this file.

#

# This file may not rely on the value of any variable other than

# LOCAL_DIR; do not use any conditionals, and do not look up the

# value of any variable that isn’t set in this file or in a file that

# it includes.

#

PRODUCT_MAKEFILES :=

$(LOCAL_DIR)/first_product_name.mk

modify “first_product_name.mk” to “hawkboard.mk”

1. Create a product-specific makefile, called vendor/<company_name>/products/<first_product_name>.mk, that includes at least the following code:

$(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk)

#

# Overrides

PRODUCT_NAME := <first_product_name>

PRODUCT_DEVICE := <board_name>

example: create hawkboard.mk in “vendor/ti/hawkboard” directory.

1. Create a board-specific directory beneath your company directory that matches the PRODUCT_DEVICE variable <board_name> referenced in the product-specific make file above. This will include a make file that gets accessed by any product using this board.
   mkdir vendor/<company_name>/<board_name>
2. Create a BoardConfig.mk file in the directory created in the previous step (vendor/<company_name>/<board_name>).
   # These definitions override the defaults in config/config.make for <board_name>
   #
   # TARGET_NO_BOOTLOADER := false
   # TARGET_HARDWARE_3D := false
   #
   TARGET_USE_GENERIC_AUDIO := true

Adding a board to android build

=====================

1. cd vendor/ti ; mkdir hawkboard
2. make TARGET_PRODUCT=hawkboard

following error comes,

build/core/product_config.mk:173: *** No matches for product “hawkboard”.  Stop.

1. cd vendor/ti; cp beagleboard/AndroidProducts.mk hawkboard/

error:

sudo make TARGET_PRODUCT=hawkboard

build/core/product_config.mk:165: *** _nic.PRODUCTS.[[vendor/ti/hawkboard/beagleboard.mk]]: “vendor/ti/hawkboard/beagleboard.mk” does not exist.  Stop

edit: hawkboard/AndroidProducts.mk

PRODUCT_MAKEFILES :=

$(LOCAL_DIR)/beagleboard.mk

to

PRODUCT_MAKEFILES :=

$(LOCAL_DIR)/hawkboard.mk

1. take beagleboard.mk as a reference.

cp beagleboard/beagleboard.mk hawkboard/hawkboard.mk

error:

sudo make TARGET_PRODUCT=hawkboard

build/core/product_config.mk:166: *** vendor/ti/hawkboard/hawkboard.mk: PRODUCT_NAME must be unique; “beagleboard” already used by vendor/ti/beagleboard/beagleboard.mk vendor/ti/hawkboard/hawkboard.mk .  Stop.

edit:  hawkboard/hawkboard.mk to

PRODUCT_PACKAGES :=

SoundRecorder

$(call inherit-product, build/target/product/rowboat.mk)

# Overrides

PRODUCT_BRAND := TI

PRODUCT_NAME := hawkboard

PRODUCT_DEVICE := hawkboard

PRODUCT_PACKAGE_OVERLAYS := vendor/rowboat/generic

error:

============================================

build/core/config.mk:126: *** No config file found for TARGET_DEVICE hawkboard.  Stop.

1. take beagleboard/BoardConfig.mk as a reference,

cp beagleboard/BoardConfig.mk hawkboard/

error:

1. take beagleboard/AndroidBoard.mk as a reference

cp beagleboard/AndroidBoard.mk hawkboard/

================================================================

modify top Makefile (i.e. android_src/Makefile) to add

ifeq ($(TARGET_PRODUCT), hawkboard)

make -C kernel ARCH=arm omap3_beagle_android_defconfig

endif

for compiling kernel

sudo make TARGET_PRODUCT=hawkboard TARGET_PREBUILT_KERNEL=path_to_kernel/kernel

===================================

1. mkdir vendor/myvendor
2. mkdir vendor/myvendor/products/
3. touch vendor/myvendor/products/hawkboard.mk

edit hawkboard.mk for adding

$(call inherit-product, build/target/product/generic.mk)

# Overrides

PRODUCT_NAME := hawkboard

PRODUCT_DEVICE := hawkboard

1. touch vendor/myvendor/products/AndroidProducts.mk

edit AndroidProducts.mk for

PRODUCT_MAKEFILES :=

$(LOCAL_DIR)/hawkboard.mk

1. mkdir vendor/myvendor/hawkboard
2. Create a BoardConfig.mk file in the directory created in the previous step (vendor/myvendor/hawkboard).

# These definitions override the defaults in config/config.make for <board_name>

#

# TARGET_NO_BOOTLOADER := false

# TARGET_HARDWARE_3D := false

#

TARGET_USE_GENERIC_AUDIO := true

1. create AndroidBoard.mk in directory “vendor/myvendor/hawkboard/AndroidBoard.mk”
