Compiling the Linux Kernel for the Kindle

[twobob]

TBH. Doing anything on the DX is ass-twitching at best without a serial cable.

READ: DON'T GET IT WRONG!

or - have a serial cable to recover the mess..

I have a DXG 2.5.8 but there is no need to guess.
Go get the code? Amazon kindly provides copies of all the relevant things on their site.
You can find the configs lying around

knc1/twobob: Thanks for the info.

I took a look at the two versions of kernels. There are too many patches, which need to be applied to both. It is beyond my capability. I will live without MOBI8.

[twobob]

fair enough. thanks for the update

Trying to compile the kindle touch kernel and can not even kick start the compilation. I think the makefile is missing. I am using ubuntu, got code sourcery installed and tested compiling an arm version of standard linux.

appreciate if anybody can give me some guidelines to get the kindle touch source code compiled.

thanks.

The (lab126) kernel source packages are notoriously crappy, with missing configs and/or files, depending on the version.

We'll need more details:

* Which exact source code package did you use?
* What did you try, and what output did that trigger, in detail?

And, stupid sidenote, but you never know: have you actually ever rolled a Linux kernel manually (native or not)? (because that would certainly help).

I tried two sources:
- Kindle_src_5.3.7_2004410010.tar.gz and Kindle_src_3.0_515460094.tar.gz

What I did is untar all the files and then follow the guidelines given at the start of the thread.

the command "make mario_mx_defconfig" means there is a make file of the name mario_mx_defconfig. but this is not found. so i'm trying to find something equivalent.


if the make file is not delivered with the source code, possible to make one ourselves? Or if is it possible to post the content of mario_mx_defconfig here?

[hawhill]

it's not that easy. This is not a file but a Makefile target. I guess you left out the answer regarding your experiences? :-)

FWIW, check the Makefile for relevant targets. As far as I remember, the config files are then be included from a subdirectory.

As "mario" is the old hardware (K3? KDX?) platform name, there will definitely be changes. Be aware that this guide was written when we were talking about devices that are not current anymore.

make imx35_luigi_defconfig is a later one... (k3's)

I dunno about the Touch...

For a K5, look for a yoshi or yoshime defconfig (can't give you a definitive answer, I think the last time I looked at this was for a K4 kernel a good long while ago).

[dicalp]

yes. you are right. It's make target not make file name. it just slip my mind. i have been using make all, make clean, etc. without really thinking.

[dicalp]

What do you think is a good try?

> make -f Makefile.help
Cleaning:
clean - delete temporary files created by build
distclean - delete all non-source files (including .config)
doc-clean - delete all generated documentation

Build:
all - Executable and documentation
busybox - the swiss-army executable
doc - docs/BusyBox.{txt,html,1}
html - create html-based cross-reference

Configuration:
allnoconfig - disable all symbols in .config
allyesconfig - enable all symbols in .config (see defconfig)
config - text based configurator (of last resort)
defconfig - set .config to largest generic configuration
menuconfig - interactive curses-based configurator
oldconfig - resolve any unresolved symbols in .config
hosttools - build sed for the host.
You can use these commands if the commands on the host
is unusable. Afterwards use it like:
make SED="/sed"

Installation:
install - install busybox into CONFIG_PREFIX
uninstall

Development:
baseline - create busybox_old for bloatcheck.
bloatcheck - show size difference between old and new versions
check - run the test suite for all applets
checkhelp - check for missing help-entries in Config.in
randconfig - generate a random configuration
release - create a distribution tarball
sizes - show size of all enabled busybox symbols
objsizes - show size of each .o object built
bigdata - show data objects, biggest first
stksizes - show stack users, biggest first

Take a look into the Makefile. Amazon left most of the documentation boilerplate and didn't care to document their own extensions. So no, it's most probably not one of these.

Rethinking the matter, I believe to recall that they had a shell script that issues the right commands? Not sure, though.

[twobob]

well.. unless I miss my mark... I think I documented some of that 1/2 way down the thread I linked.

in terms of generating a config.

if i use "make mario_mx_defconfig ", error is happen.
what can i use isteade of "make mario_mx_defconfig"?

[Jackie Im]

hi~
I bought kindle paper white 2nd.

I typed "make mario_mx_defconfig" command in kernel folder.
but error was happened.
error was "No rule to make target 'mario_mx_defconfig'. Stop."
