No accelerometer support No Will be supported in the upcoming releases. Android Software Setup Unpacking Sources and Patching ● Install the build prerequisites (http://source.android.com/source/initializing.html) ● Unpack the tar.gz file: $ tar xzvf i.MX53-QSB-Android-Release4.0.tar.gz $ cd i.MX53-QSB-Android-Release4.0/scripts ● Run the script “download_android.sh” $ ./download_android.sh The Android sources will be downloaded from the public repositories. This takes a while. ● Run the script “patch_android.sh” $ ./patch_android.sh ● Run the script “apply_qsb_patch.sh” $ ./apply_qsb_patch.sh ● By default, the Gingerbread build-system now requires a 64-bit machine. The sources can be patched to build Android on 32-bit machines. Only run this command if this is the case for you (tested on Ubuntu 10.10): $ ./fix_android.sh Building Android for the i.MX53 Quick Start Board ● To build the bootloader, kernel, and android filesystem for the first time: ○ Run the script “build_android.sh” $ ./build_android.sh imx53_qsb all ● Build just the bootloader: ○ Run the script “build_android.sh” 6/6/2011 Adeneo i.MX53 QSB BSP for Android Gingerbread v4.0 Page 8 $ ./build_android.sh imx53_qsb uboot ● Build just the kernel: ○ Run the script “build_android.sh” $ ./build_android.sh imx53_qsb kernel ● Build just the android filesystem: ○ Run the script “build_android.sh” $ ./build_android.sh imx53_qsb android Setup SD Card and Flashing Binaries NOTE: /dev/sdx parameter is your SD Card device. For example: /dev/sde NOTE: if you are overwriting an SD Card that you were using for previous releases, make sure you clear the previous environment settings (since they are saved on the SD Card and will override the default parameters): $ sudo dd if=/dev/zero of=/dev/sdx bs=1M count=1 Flashing binaries built using the above build scripts: ● Run the script “flash_android.sh” $ ./flash_android.sh /dev/sdx ● When using the provided build scripts all binaries are copied automatically to the “out” directory. This is the location that the “flash_android.sh” script uses for binaries. Flashing prebuilt binaries: ● Run the script “flash_prebuilt_android.sh” $ ./flash_prebuilt_android.sh /dev/sdx ● This script copies the prebuilt binaries located in the “prebuilt” folder. Setup Boot Environment The boot environment is already setup to boot the linux kernel and android filesystem from the micro SD card. Voltage Fix: There is a temporary workaround to fix mosaic observed when playing video. This increase in VCC voltage is only required with the MX53 T2.0 silicon. Boards that are labeled SCH-26565 REV D or later do not require this workaround. 6/6/2011 Adeneo i.MX53 QSB BSP for Android Gingerbread v4.0 Page 8 From the FSL Release Notes: “MX53 TO2.0 silicon has issue that causes video quality poor with yellow blocks on the screen when playback some Videos. And we have a Software Workaround which is little dangerous to the silicon. This workaround increases the VPU voltage by increasing the VCC to 1.35V. We did not include this workaround code in the release, and suggest that you wait for TO2.1. Because It will shorten your silicon's life cycle, so please pay attention to this before you decided to do so” # setenv fix_voltage 'i2c mw 0x48 0x2f 0x62; i2c mw 0x48 0x3c 0x62' # setenv bootcmd 'run fix_voltage bootcmd_SD1 bootcmd_SD2' # saveenv 4.3” SEIKO 24bpp LCD (MCIMX28LCD) Supported by default. If necessary do the following: ● When u-boot starts to load, press ‘spacebar’ to pause. # setenv bootargs_android ${lcd} # saveenv ● This will save the environment variables to the SD card. Restart the board and android will load. 7” CHUNGWA 16bpp LCD ● When u-boot starts to load, press ‘spacebar’ to pause. # setenv bootargs_android ${claa_lcd} # saveenv ● This will save the environment variables to the SD card.

    Vol-4 Issue-5 2018 IJARIIE-ISSN(O)-2395-4396 Android Development based on Linux Rohan Veer1, Rushikesh Patil2, Abhishek Mhatre3, Prof. Shobhana Gaikwad4 1 Student, Computer Technology, Bharati Vidyapeeth Institute of Technology, Maharashtra, India 2 Student, Computer Technology, Bharati Vidyapeeth Institute of Technology, Maharashtra, India 3 Student, Computer Technology, Bharati Vidyapeeth Institute of Technology, Maharashtra, India 4 Professor, Computer Technology, Bharati Vidyapeeth Institute of Technology, Maharashtra, India ABSTRACT Android software development is used to produce apps for mobile devices that includes an OS (Operating System) and various applications. It can be used to make video applications, music applications, games, editing software etc. The android operating system was showcased by Google after which android development started. The Google initially released the android operating system on 23th September 2008.Google hired some developers and started building applications which started app development and fast production of android applications. The applications and operating system for android are written in Java as the android is based on Linux so it was difficult at the start to write programs for android. But as the technical skills were improving to debug an application so it became easier for developers to solve the issues and debug the errors in the applications. The first android operating system was able to perform some basic task like messaging, calling, downloading some specific applications etc. After that Google released various versions of android operating system with newly added features and design. With every new version of android speed of device and user experience were getting much better in day to day life.
