Building kernel for kindle fire

[xdadevelopers-user]

Has anyone successfully built the kernel or a kernel module against the source released by Amazon? I have tried the following and get a error about a missing arch/arm/mach-omap2/Makefile:

$ export CCOMPILER=/path/to/android/toolchain/bin/arm-linux-androideabi-
$ make ARCH=arm CROSS_COMPILE=$CCOMPILER mrproper 
$ make ARCH=arm CROSS_COMPILE=$CCOMPILER omap_4430sdp_defconfig 
$ make ARCH=arm CROSS_COMPILE=$CCOMPILER modules

... a lot of stuff builds then ...

... arch/arm/mach-omap2/Makefile: no such file or directory

Any ideas?

I was just having this discussion last night with a fellow dev. Its definitely missing when it obviously shouldnt be. and I believe the board number is kc1 at least according to the stamp on the board.

Anyway, I'll be contacting them shortly. Their source code is incomplete.

arch/arm/plat-omap is missing as well.

I am trying android_4430_defconfig, the omap one doesnt have CONFIG_ANDROID & too many driver build issues to continue fiddling with

i start the channel in freenode #kf-dev

Here are my makefile replacements, I dont consider these correct, they are a big hack & a work in progress that gets vmlinux linked for me.

driver wise i have laak display off, *hdmi* off, and lgd display on.

havent debugged further.

Did you guys pull the configuration from the device? I didn't find it at /proc/config.gz

We cant get it unless amazon gives it to us...

Forgive me, I have not not built a kernel in a long time. Why can't the configuration file be pulled from the device? I use to just do something like

adb pull /proc/config.gz

config.gz does not appear to be in /proc on this device but we should be able to pull the configuration from somewhere

Its not in /proc and i cant find it elsewhere. I agree there SHOULD be another way to do it. The only other way I know is to take the kernel by itself and run the extract-ikconfig script. But that doesn't even work. I've tried it multiple times. And people seem to be avoiding answering my question on here if there is another way. I'm sure there is...

Isn't the processor similar to galaxy nexus? Try using some of those files and as for the config, they may not have it in /proc, galaxy s doesn't from what I know, that makes you dependent in good source release. Start with galaxy nexus source and work from there I think

The kernel stores its config only if configured to do so (the IKCONFIG options).

So a kernel with IKCONFIG disabled (most stock kernels of any phone I've ever worked with) won't have the config available anywhere.

Until we can get Amazon to cough up a complete kernel release including config we might start with the omap4430_sdp config with console on ttyUSB0. The KF certainly feels like the BSP was done by the ODM, so hopefully the kernel changes are minimal from the TI reference board...

I was looking at the Droid Razr too

Alright.... Now I cant seem to get the kernel to compile past this

  CC      kernel/time/timekeeping.o
make[3]: *** No rule to make target `security/smc/omap4/tf_comm_mshield.o', needed by `security/smc/omap4/tf_driver.o'.  Stop.
make[3]: *** Waiting for unfinished jobs....
  CC      security/smc/omap4/scxlnx_device_mshield.o
make[2]: *** [security/smc/omap4] Error 2
make[1]: *** [security/smc] Error 2

Any ideas?

cant disable the smc driver. (won't let you)

 

[Groundhack]

Is there anything helpful here? I don't know jack about android programming

There's a new drop for 6.2 now:

http://www.amazon.com/gp/help/customer/display.html?nodeId=200203720

Maybe that'll have a working kernel tree?

No .config ... haven't looked much beyond that yet.

kernel hasn't changed.
