Introduction[edit | edit source]
Texas Instruments provides the Android developement kits for the Sitara platform, but an official release for the DM814x/AM387x processor is not yet available. However, it is possible to build Android 4.0.3 Ice Cream Sandwich (ICS) for the DM814x/AM387x processor and make it run on the Naon/Maya/Dido SoMs.
Useful links[edit | edit source]
- Get started building Gingerbread for TI816x or TI814x with support for hardware-accelerated multimedia
- Rowboat Git repository
- Manifest file used for building
- Downloading the source tree
Configuring the build system[edit | edit source]
Please follow the instructions to initialize the build environment and in particular download the repo tool and the AOSP source code.
Please note that the required manifest file is rowboat-ics-ti81xx.xml. Please enter the following commands to update the source code:
repo init -u git://gitorious.org/rowboat/manifest.git -m rowboat-ics-ti81xx.xml repo sync
Building Android[edit | edit source]
Assuming that rowboat-android is the directory containing the full AOSP source code:
- kernel contains the Android kernel tree that must be patched to add Naon support
- out/target/product/ti814xevm/ will contain the created root file system
To launch Android build (please note that it will take some time, depending on the host system performaces) enter the following commands:
export OUT_DIR_COMMON_BASE=/home/shared/devel/dave/naon-DAA/sw/linux/porsaria/android/rowboat-android/build-dir export USE_CCACHE=1 export CCACHE_DIR=/home/shared/devel/dave/naon-DAA/sw/linux/porsaria/android/rowboat-android/cache make TARGET_PRODUCT=naon OMAPES=6.x
- N.B: The Makefile must be modified at rows 71-73 so that the kernel configuration file naon_ics_defconfig is used instead of the default one.
ifeq ($(TARGET_PRODUCT), naon) ifeq ($(KRN_DBG),1) $(MAKE) -C kernel ARCH=arm naon_ics_defconfig V=1 CONFIG_DEBUG_DONT_REORDER_CODE=1 else $(MAKE) -C kernel ARCH=arm naon_ics_defconfig endif endif
- build tutti gli script per il build di android
file modificato build/core/root.mk aggiungendo riga 13
ifeq ($(TARGET_PRODUCT), naon) export SYSLINK_VARIANT_NAME := TI814X CLEAN_RULE := syslink_clean sgx_clean kernel_clean clean rowboat: sgx else
riga 60
endif
riga 83
ifeq ($(TARGET_PRODUCT), naon)
ifeq ($(KRN_DBG),1)
$(MAKE) -C kernel ARCH=arm naon_ics_defconfig V=1 CONFIG_DEBUG_DONT_REORDER_CODE=1
else
$(MAKE) -C kernel ARCH=arm naon_ics_defconfig
endif
endif
riga 114
ifeq ($(TARGET_PRODUCT), naon) sgx: kernel_build ti81xx_kernel_modules else
riga 125
endif
- avvia_dbg.sh esegue il make con le opzioni di DEBUG per il kernel
- mkRFS.sh crea il RFS
- Nota: ho disabilitato la creazione del tar che nn server se si usa NFS. file build/tools/mktarball.sh
- clean.sh cancella la cartella di build out in modo che il successivo make compili tutto da capo.
