increased touchscreen sensitivity and made touchscreen more usable close to the borders (kernel change)

fixed heap size issue to get much more programs running (e.g. nook app, kindle app, etc.)

fixed screen turning animations and previews in taskswitcher

sd card access and secure storage support

turned off the debug screen flashes and vibrator

added display timings

sd card image now usable on 4gb cards

changed to a self compiled kernel to make these things work

reduced compressed image size

sound support

patched in some graphics improvements. Can play non-hd videos from m.youtube.com

sdcard storage

initial release

Graphics acceleration

Accelerometer

Wireless!

Touchscreen

Buttons

Sleep/Wakeup

The accelerometer behaves funky. Will try to fix this.

The Gallery app crashes when opening an image. Not my fault, it's broken in the emulator from google too.

DSP e.g. no hardware video decoding (and will possibly never work before the AOSP release)

First of all I have to thank the CM people, especially mbm, nemith, fattire and cvpcs for their work on gingerbread which helped me a lot in understanding where to look and what to patch.The whole thing is based on the honeycomb preview emulator images, some of the B&N modules+driver, pieces from the upcoming CM7 and manual patching ARM assembler in libraries, writing ugly scripts to hack around various issues, a lot of time and many brain cells.The unzipped image is around 3.5gb and fits on 4GB SD cards.MD5 (nookhoney04.img.zip) = 27396e63396a59a25f5d6fdbe0341276v04 - 02/07/2011v03 - 02/05/2011v02 - 02/02/2011v01 - 02/01/2011What works:Known issues:Doesn't work:Q: Why?A: I thought it would be fun. It was and still is. And now developers have an actual device to test their apps on instead of relying on the slow emulator.Q: How?A: I'm planning to write a blog post. Mostly learning how Android works, debugging, patching, reusing binaries from different sources, finding easy ways to reach a goal, try and error, a lot of brain power.Q: During boot I get stuck at the Android screen with the blinking cursor.A: It seems to be a timing issue with mounting the partitions. Sometimes rebooting helps to get it booting. If not a different SD card might to the trick.Q: Why is there no Market app installed?A: There's no legal way to distribute the google apps with a ROM.Q: Angry Birds, Nook reader, Kindle app?A: Yes.Q: I want to port Honeycomb to device xyz... send me the instructions how to do that now!A: I like the 'I' in that sentence - but there are no instructions, no source, no nothing. Learn and read about Android, Android porting, making custom roms, embedded systems, ARM assembly, driver programming, programming in general, the Linux Kernel and much more - and when you're comfortable and have experience with all of that come back and do your port.Q: Can you port Honeycomb to device xyz?A: I don't have xyz. And even if device xyz would magically appear at my front door doesn't necessarily mean I'll have the time and motivation to port anything to it.Q: I want to use a different kernel what changes did you make in the kernel?A: https://github.com/rbrune/nook_kernel Q: Where can I donate?A: I don't want any money. If you want to put your money to good use donate to a humanitarian organization and/or the EFF.--Rafael Brune
