The document provides instructions for building and setting up Android 5.0.2 on the Zedboard. It describes compiling the first stage bootloader (FSBL) and U-Boot, the Linux kernel, and the Android system image. It also explains how to create a bootable SD card with the required files and how to configure the hardware switches and ports on the Zedboard. Following these steps will result in a fully booted Android 5.0.2 system on the Zedboard.

©SIProp Project, 2006-2008 31 Download source code & build Install build tools following Google Android Site https://source.android.com/source/downloading.html Download source code & build repo init -u https://github.com/noritsuna/zedroid_manifests -b zedroid-5.0.2_r1 repo sync source ./build/envsetup.sh lunch zedboard-userdebug make
©SIProp Project, 2006-2008 32 Appendix: OpenGL/ES support If you use “lunch zedboard-userdebug”, this Android is for OpenGL/ES 2.0. Zedboard doesn’t have GPU. My Android uses software renderer. It’s soooooooo slow. If you use OpenGL/ES 1.2, it’s better to use. Android’s OpenGL/ES current version is “2.0”. Some applications require “2.0”. Special Options OpenGL/ES 1.2 version lunch zedboard_GLES12-userdebug OpenGL/ES 2.0 version lunch zedboard_GLES20-userdebug
©SIProp Project, 2006-2008 33 Mark up ARM RAM image info Android’s RAM image is NOT for u-boot. sudo apt-get install u-boot-tools mkimage -A arm -O linux -T ramdisk -a 0x2000000 - n "Zedboard ramdisk" -d [Android output dir]/ramdisk.img uramdisk.image.gz “uramdisk.image.gz” file is RAM image for u-boot.
©SIProp Project, 2006-2008 34 Setup Zedboard
©SIProp Project, 2006-2008 35 Prepare Hardwares: SD Card 1/2 4GB SD Card Partition: 1st primary: VFAT(FAT32) over 1GB with boot flag 2nd primary: ext4 over 1GB 3rd primary: ext4 over 500MB 4th primary: Linux Swap over 500MB Copy Files [Xilinx SDK dir]/boot.bin [kernel dir]/arch/arm/boot/uImage [kernel dir]/arch/arm/boot/dts/devicetree.dtb [Android dir]/uramdisk.image.gz To 1st partition
©SIProp Project, 2006-2008 36 Prepare Hardwares: SD Card 2/2 4GB SD Card Copy Files [Android output dir]/system/* files with permission info To 2nd partition [Android output dir]/userdata/* files with permission info To 3rd partition
©SIProp Project, 2006-2008 37 Prepare Hardwares: Zedboard DIPs JP2, JP3, JP6: “Short” JP18: “1V8” is “Short” MI02, MI03, MI06: “3V3” is “Short” MI04, MI05: “GND” is “Short”
©SIProp Project, 2006-2008 38 Prepare Hardwares: LAN, HDMI, OTG Required LAN, HDMI If you don’t connect them, it doesn’t boot up. Required 2 more ports: USB Hub USB port is OTG only. Other USB port is NOT USB.
©SIProp Project, 2006-2008 39 Power ON! Insert SD Card Connect AC Adapter and Turn on Power Switch! Please wait 5-10 mins. Because when 1st boot, ART compile all applications to native binary. Enjoy!

My Android uses software renderer. It’s soooooooo slow. If you use OpenGL/ES 1.2, it’s better to use. Android’s OpenGL/ES current version is “2.0”. Some applications require “2.0”. Special Options OpenGL/ES 1.2 version lunch zedboard_GLES12-userdebug OpenGL/ES 2.0 version lunch zedboard_GLES20-userdebug
