Android Jelly Bean running on Pandaboard (ES)
Linaro team made a huge step forward towards an automated kernel and full Android builds. Below are these simple steps I did to get Android JB running on my Pandaboard ES with LG 10″ with touchscreen. Compare it to our old How-to: https://www.chalk-elec.com/?p=1426 and feel the difference 🙂
- Go to http://releases.linaro.org/12.10/android/leb-panda/ and proceed with “Binary Image Installation” steps. Windows users can get file pandaboard.img.bz2, unzip it and write to SD card with Windows32DiskImager utility.
- Update boot.scr file in boot partition of SD card with correct LCD resolution (1280×800 for LG panel). Ready boot.scr file is here: boot.scr
- After step 2 you should get LCD working. You will see Android GUI and can use mouse. Adding touchscreen requires some kernel re-build.
- Download file linaro_kernel_build_cmds.sh to your Linux computer, change its attribute (+x) and run it. It will automatically download and re-build kernel for Android. Final kernel is located in ./linaro-kernel/out/arch/arm/boot folder (file uImage)
- Now you should update kernel config to include touchscreen support and re-build kernel again. Find file .config in ./linaro-kernel/out folder and uncomment/add options CONFIG_HID_MULTITOUCH=y and CONFIG_HID_NTRIG=y – first option is for old AUO panel, second is for new LG panel. You can add both just in case 🙂
- Comment line “mkdir out/modules_for_android” in script linaro_kernel_build_cmds.sh and run it again. Copy final uImage file to boot partition of your SD card. You can also skip these steps and get my final uImage here: uImage
- Last step is to configure touchscreen as an internal device to fit with LCD panel size. Download file Vendor_1b96_Product_0007.idc and put it to folder /usr/idc on system partition of SD card.
Final SD card image (4Gb card) is here: Android 4.1.2 for Pandaboard(ES)
