The image fom Marek for Glo Kobo_Glo.7z is not working on Aura HD,
but we can use all the partition's content from that image. To produce a working image, I choose the method retaining all the original content from the auraHD SDCard,
- so the u-boot,the serial#,the HW_CONFIG part and waveforms info - except the kernel which must modify and compile. The kernel can be download from naberius.de: kernel.tar.gz.
It contains all the necessary setting for the E-ink display, the only misbehaved part is the IR-touch - the coordinates must swap and scale both for x-y and left-right.
The patch I made you can find here: auraHD.diff. It is not complete - after the screen rotate there is a problem again - must finalize the code.
Also must change some settings in the /system partitions (keymap,etc.): system.diff. The corrected vold.fstab seems to be good (the ....mmc2 path exists in /sys), but the SDCard does not mounted
by vold, so I mounted it in init. To avoid the LED blink, I wrote a small script to switch it off in init.
Now if you flash the produced image and put this SD inside the Kobo (inside, so not to the external slot!), it started - you can see the boot animation, etc. - Android is working, you have Wifi connection, Back button (the old Light one) and Sleep/Poweroff button. The tolino ereader app don't work, therefore no USB now.
And the final words: it seems that - as with the Nook - the Android is not a good operating system for this type of devices without a very high level of customizations. Until you can work with the corrected (for ex. Settings) application everything is fine - crystal clear b/w screens everywhere - but any other program use color buttons, animations,etc. which is designed for color screens and the look is ugly in this device. Maybe the e-ink refresh also have some trouble because a notifiable shadow remain on the screen.
Because this device main purpose is reading an e-book ( and the original reader app is excellent), I decided to not use Android in this present stage. In the case somebody modify the u-boot booting from the external SD when the ligth button pressed, it can be useful....
