These are some rough scripts I found useful bringing up a hacky Froyo (Android 2.2) on my M001: * build_sd_boot.sh - script to build an SD card which is mounted. * build_sd_boot_image.sh - script to use an SD card to build images for distribution * overlay/ - files to overlay over the default AOSP source tree. * script/ - script directory for FAT partition * patches/ - patches to be applied manually to the AOSP tree, to get things to work (read patches/README). You'll need linux w/ mkimage installed in order to use build_sd_boot.sh. In this form, these scripts should allow you to take an AOSP source tree and make a boot-from-SD-card Froyo install. I think it would be a good base script for making an Eken installer SD card image, as well. Please do whatever you want with it, but -please- share anything you find. The only way to move forward is by working together. BTW, I know that having this pile of scripts is a horrible horrible hack, and most of it could be integrated directly into the Android tree. When I first did this, I didn't know if it would work at all, so doing it this way made it reproducible without requiring major effort on my part. If this becomes a real effort then we should -undoubtedly- move into a proper custom Android tree and use their build process for everything. Enjoy, - Angus (aka projectgus) NB: overlay/data/busybox/busybox is "benno's" precompiled Android busybox from his blog, details & source available at that link: http://benno.id.au/blog/2007/11/14/android-busybox ************ KNOWN ISSUES ************ * No video acceleration (not even double-buffering) * No touchscreen calibration (comes with my M001 calibration, copy /data/wmt/touchcal to /system/etc/touchcal to bring yours over.) * No suspend/resume (same as old firmware.) * No music player (as you're booting from the SD card, Android doesn't detect one for media.) * Wifi is suspect (please test.) * Some apps may not work properly due to the graphics mode being set at 32-bit color not 16-bit. * Unstable, unreliable, hacky and horribly slow. ;) * Uses horribly hack-mixup kernel, kernel is built from "my" copy of VIA's tree with make -j8 ubin modules ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- KERNELRELEASE=2.6.29-00236-g4f8dbbb-dirty ... then modules are partially taken from existing Android distros, as some are different/missing. Eww. **** TODO **** (This is a massive list atm, this is a very rough hack!) * Change from using 'generic' board config to a specific wm8505 config * Use BUILD_ flags to disable unnecessary Froyo features * Test Wifi properly * Test audio (will probably not work.) * Test battery level tracking. * Test SetCPU (should work.) * Port or recreate the touchscreen calibration app. * Make a proper installer package instead of boot-from-SD. * Disable 16Mb VPP "memory block" allocation (I think does nothing atm.) * Screen rotation support. * Double-buffering support (default method doesn't work, but may be possible.) * Graphics acceleration support (???) * Move from binary-only components (wifi module, etc.) to OSS ones. Kernel-side: * Enable double-buffering * Apply compcache patches for "ramzswap" * Suspend/Resume support * Work out how to support RGB565 16bpp instead of forcing 32bpp.
