Unable rebuild Galaxy Note2 LTE (N7105)

[aatjitra]

Hi Experts,

I have tried to rebuild the kernel for Galaxy Note2 LTE (N7105) from the source downloaded from opensource.samsung.com.

The kernel can be compiled without error and I use ramdisk from latest firmware to create boot.img. After that, boot.img can be flashed without problem to the phone and it can reboot correctly.

But, the two button (MENU and BACK) does not work and exFAT module can't be loaded.

I have no problem doing this for Galaxy S3 (i9300) and Galaxy Nexus (i9205) but only this time I always fail.

Can anybody point what are the things I missed out?

Thanks in advance.

IIRC, the sources for touchkeys are missing for some reason in this release. There should be a thread about this, at the beginning of this development section.

What's your error with exfat module?

Thanks for pointing that...

I do comparison between 7100 source and 7105 source and I found 1 folder missing under /driver/input/keyboard/cypress...

The error message I got while trying to load the module is Exec Format Error as attached.

Put this command "if(!strncmp("exfat_", mod->name, 6)) return 1;" under kernel/module.c (original code by AndreiLux) seems doesn't help..

Sorry for this noob questions...

EDIT: Found something interesting reading about FTRACE... going to test it tonight...

After playing around with N7100, I manage to make the capacitive button works again.. but no succes to load exfat module

Any idea highly appreciated...

There also is a thread here already: trying to load proprietary kernel modules, like exfat.

There are already some information.
Also, what did you change at the kernel already?

Yes. I read that thread yesterday. I also got the same message as mentioned in that thread.

I believe something is wrong with the source as I tried to rebuild the kernel without any change to the code. This is normally what I did, I mean, I will try to rebuild the kernel without modification to see if it is working. If yes then I start to modify the kernel based on cherry pick enhancement and recompile it.

So when I tried to rebuild this N7105 kernel, I found that the kernel is not working properly.

Anyway, thank you very much for your respons. Really appreciate that.
