What I did was a temporary hack to get the firmware actually running. However, for these options to work, the native JNI libraries must be loaded (framebuffer, pdf reader, and etc). For those to work, we need to get GLIBC working, which, I've worked literally 11 hours yesterday on with no success. Seriously, I counted the hours. Cross-Compiling open-source software is no fun. I mean, it's basically guess and check. What version of binutils, what version of gcc, and what version of glibc will work together. Most combinations will fail. Using precompiled toolchains also fail.

So maybe it's easier to backport the kernel? I mean to try backporting it during the next week, as soon as I'm done with my exams.

Sure, go ahead. I've successfully compiled GLIBC 2.12.1 and it still doesn't work, so that road's dead.

Is it possible to partially inject the elements of the firmware 4.0.1 to firmware 3.x.x like pdf viewer?

yifanlu · 11-26-2011, 11:28 AM

Nope, that's what I tried for the last few days. All the native libraries are compiled with glib 2.12.1 and the kindle 3 only has 2.5. And the 2.12.1 was compiled for kernel 2.6.33.

I've started working on it. I think I'll have it compiling by the end of the week, but then I'll need someone to test it since I don't have a serial cable.

I guess the reason would be different for everyone but, personally speaking, the main reason I'd like to see a 4.x firmware running on a K3 would be to possibly allow access to the new KF8 format.

From what I'm hearing, which admittedly isn't a lot, it sounds like the K3 probably won't be included in the "latest" generation to get KF8 format capability. Of course, none of the K4s have it at this point either, so I guess it's a moot point.

I suppose I can ask, even if I don't know if someone can answer... 'make clean' doesn't work, probably because the amazon source is incomplete and doesn't include the unneeded drivers and stuff. How do you do something equivalent? I need it because when I change something in makefiles those changes aren't picked up, probably resetting the compilation would make it work? I already tried deleting all *.o files but it didn't work.

giorgio130 · 12-18-2011, 04:29 PM

I got it to compile till the end, using many hacks. Now I need to clean the source of the binary files and upload it to github; then I need someone to test it. I'm afraid I can't do this by myself since I don't have a serial cable. Another option would be for me to buy an already made serial cable for kindle 3, but I didn't see anyone selling those. Anyone volunteering for testing?

Am I the only one interested in this??

I am interested, and I am sure others are too. We all have limited time and need to mostly concentrate on one thing at a time. It is good that each person works on the piece that interests them.

I would like to see all these little pieces come together in a way that works on all the (non android) kindles. I think that even the new launcher menu being developed for the Touch could be "simulated" on previous kindle models.

And backporting is a good thing. If amazon is not interested in adding recent features to older kindles, at least some of us are.

I am interested in this though i only have a kindle DXG with 3.3 firmware. With Yifanlu's brick-proof kernel i might recover from brick without a serial cable. At least i hope so.

yifanlu · 12-20-2011, 11:50 AM

@giorgio130 did you backport the kernel or the libraries? I've backported libc and various other libraries weeks ago and it didn't work. If you backported the kernel, then, just add the recovery initramfs to it.

giorgio130 · 12-21-2011, 08:20 AM

I've backported the kernel but I'm not sure it can boot, if it doesn't even boot it would brick the kindle without a possibility of recovery without a serial cable. Moreover serial output can tell what's going wrong, so I need someone who has it to test.

seaniko7 · 12-21-2011, 08:43 AM

Send me your kernel, I'll test it and post output.
btw., did you include recovery initramfs as yifanlu mentioned ?
