Where to find HW KB scancodes

---

I'm trying to make proper keymaping for X1 HW keyboard, but i'm stuck at the beginning. How to get keys scancodes?

Is there any WM or Android app that can display scancode on key press?

I don't know anything about scancodes, but could this be useful?

There is (i believe, according to the Kovsky Linux Wiki) a fully working keymap file here. i've had a quick look and it looks pretty complicated, but complete, just have to find a way to implement it in android i guess

We just need to replace /system/usr/keylayout/qwerty.kl with that I believe.

Apparently the filesystem is only in RO mode. Let me try to re-mount with rw.

Edit: Nope, doesn't allow me to go to rw mode... don't know how we can replace it.

you need to uncompress the squashfs or the zImage file systems, wherever the file is, overwrite the keyboard and recompress them

I tried messing around with the keyboard mapping as well but messing with the android files that haret is using is over my head

Edit: Read post below for information on how to mount and edit the 2 files (rootfs.img and system.sqsh)

I basically extracted and changed the file and recreated the sqsh, but it was 4.0 which the android kernel doesn't support. I'm going to install a lower kernel (2.6.29)- and install mksquashfs that does support making 3.1 sqfs'.

Edit: Got squash-tools 3.4.1 installed on CentOS 5.3. Changed qwerty.kl into the Xperia keymap. Remade squash file and booted up Haret. Kernel boots up squashfs fine. Time to try if the keys actually work like it should.

Edit2: Keys are even more messed up with this key layout than original qwerty. I looked at the both files and they look hugely different... the format is complete different as well. Also, its no point opening up and recompiling the sqsh, qwerty.kl is symlinked to /etc/keylayout/qwerty.kl, which is in /init.etc/keymaps in the rootfs.img.

How to uncompress/remake squashfs. You need squash-tools 3.4.1 to make a squashfs 3.1 filesystem needed for Fatsal's android kernel (assuming root access).

# unsquashfs system.sqsh; cd squashsh_root/
... do your changes to sqsh here ...
# makesquashfs ./ system.sqsh -le

Make sure you do not forget the -le flag, the -le flag was also used in the original file. Check the flags used in the compression of the original sqsh file for reference by going:
# unsqashfs -s system.sqsh
Here's how to mount rootfs.img and location of the keymap that's being called by a symlink in system.sqsh (qwerty.kl) (assuming root access):

# mkdir /mnt/rootfs
# mount -o loop rootfs.img /mnt/rootfs
# cd /mnt/rootfs/init.etc/keymaps

rootfs.img is writeable after mounting, so you can make changes and the unmount and copy the new img onto your sd card.


Here's the qwerty.kl included with fatsal's android build, if someone would be kind enough to look at this and modify this one according to it?

I won't have time to try it out X1iser, but I'll put this file into the rootfs.img, and upload it for you to try it yourself.

Edit: Here it is,

Replace that rootfs.img with your current one.
