linux kernel module compilation + insertion

gdkags · 09-21-2010, 10:53 AM

Hi,

has anyone ever compiled a custon kernel module for the Kindle 3 (i guess 2 or 1 whould be alright).

I used the Source linked from https://www.mobileread.com/forums/showthread.php?t=95968
But i am using firmware 3.0.2, this could be a problem because the kernelversion differs. Where did you get the link to the source from? I searched for it but came up with nothing.

regards.

//edit well, i just found the source code page. I guess, i might have to revert to 3.0.1 to build a custom kernel module

The source should come out once the 3.0.2 becomes official, and not an early preview.

And, yes, several users already have replaced the kernel on K2 devices, check this forum

.

(if you don't want to touch the core kernel, and just want to inject modules, your x-compile toolchain will have to match *exactly* the one used by the lab126 guys (ie. K 2.6.26, glibc 2.5, binutils 2.18.4 (not sure about binutils right now, something like that xD), gcc 4.1.2).

yaaay, building my own toolchain really sounds like loads of fun :/
I guess I have to do this, because i am not sure I would be able to recover my kindle if my comiled kernel goes haywire.
Are there any fallbacks for such a scenario? I mean, without soldering.

edit: maybe you/somebody want/s to tell me what the kernel expresses with:
module: no symbol version for struct_module

I wrote a guide on compiling the kernel for Kindle 2 here: https://www.mobileread.com/forums/showthread.php?t=91862

(I also linked to a pre-compiled toolchain)

The only differences for Kindle 3 is:
1) Download the Kindle 3 source (duh)
2) For step 2, instead of "make mario_mx_defconfig", do "make imx35_luigi_defconfig"
