General :: Specify Kernel Module Load Path In Config File?
Sep 28, 2011
I needed a tun.ko module for my kernel, so I tried compiling my own kernel.
The kernel did build OK, and also boots OK, the only problem is that I cannot load any modules.
It seemes, that the module tools (insmod, modprobe etc) looks for the modules in /lib/modules, and I have them in /system/lib/modules, so my wifi does not work, as I cannot load the module.
Where I can specify the kernel module load path in the .config file?
Example:
# cd /system/lib/modules
# ls -l
-rw-r--r-- root root 315403 2008-08-01 14:00 bcm4329.ko
-rw-r--r-- root root 211573 2008-08-01 14:00 tun.ko
# modprobe bcm4329.ko
[Code] .....

I'm tinkering with building and installing Android from source. Basically I've got it down fairly well, but I seem to have run into a bit of a problem with the wlan module, probably from HTC.
Having pulled the 2.6.27 kernel sources and built that with a .config pulled from the phone, and using that as the kernel image instead of the prebuilt one, I get the following wifi failure message in dmesg:
wlan: version magic '2.6.27-00205-gf2dabc0 preempt mod_unload ARMv6 ' should be '2.6.27-00392-g8312baf preempt mod_unload ARMv6 '
probably because the .config I pulled from the phone has:
CONFIG_LOCALVERSION="-00392-g8312baf"
So I rebuilt with the '00205' localversion and now I get in dmesg:
[61.122497] wlan: Unknown symbol trout_pwrsink_set
but trout_pwrsink_set was changed to htc_pwrsave_set way back in February:
[ARM]: trout: Switch from trout_pwrsink -> htc_pwrsink 33/8933/1 http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=44a01f...
I'm clearly getting an obsolete wlan module somehow, Any ideas for how I can get a wlan module that goes with the '00392' kernel would be appreciated.

<3>[ 154.264768] bcm4329: version magic '2.6.35.14-cyanogenmod-g1ad182f preempt mod_unload ARMv7 ' should be '2.6.35.14-cyanogenmod-g704f542 preempt mod_unload ARMv7 '
I've successfully built the samsung-kernel-crespo kernel from the cyanogenmod git. I unpacked a working ramdisk from a nightly and repacked it with my kernel, when i try to load the module i get the above error, The "extraversion" info that in the "about phone" tab in sittings is 2.6.35.14-cyanogenmod-g704f542, as well as the version of the modules. but for some reason the kernel is looking for that 'g1ad182f ' instead.
I loaded the module via fastboot boot boot.img and i didnt full on flash it to the phone. I backed up the working kernel module and put the new one in /system/lib/modules, rebooted the kernel and the wifi is still giving me an error.
If i try to manually insmod the module and it hangs, if i use modprobe then lsmod it says its "loading" but never loads.
the phone im working on is a nexus s if that matters.

If a kernel does not have the Advanced Routing feature (which is needed for VPNC widget - Cisco VPN) is it possible to add this via module like tun.ko module? The Adv. Routing is not needed for connecting but the connection is soon lost.

I am trying to compile a WiFi driver (ath6kl) for my Sony Xperia E (Android version: 4.1.1, compilation: 11.3.A.0.47). I have downloaded the source code for compilation 11.3.A.0.47 from here: developer.sonymobile.com/downloads/xperia-open-source-archives/open-source-archive-for-build-11-3-a-0-47
I have compiled required kernel modules (cfg80211 and ath6kl_sdio), but I have encountered some problems during this proccess. I don't understand why on my android device (in /system/lib/modules/ath6kl) there are two modules: ath6kl_sdio.ko and cfg80211.ko (first one depends on the second one). But when I look at my sources, I see the following module dependencies for ath6kl: ath6kl_sdio -> ath6kl_core -> cfg80211. So there are 3 modules instead of 2. Anyway, after some modification (I merged ath6kl_core and ath6kl_sdio into one module) I managed to compile ath6kl.
I have replaced compiled modules in /system/lib/modules/ath6kl on my android device, then rebooted and I got the following error:
<4>[ 23.055226] ath6kl_sdio: disagrees about version of symbol cfg80211_sched_scan_results
<4>[ 23.055251] ath6kl_sdio: Unknown symbol cfg80211_sched_scan_results (err -22)
[Code]....
I am very desperate cause I want to modify this driver (to be able to calculate some network statistics) but I cannot load modules at all so I am stuck.

A long time ago, on a 386 far, far away, some people would regularly boot Linux from DOS/Win16/Win32/Win95/etc... using a utility called loadlin. Loadlin would basically grab the system from the short and curlies, and load a target kernel into RAM, and jump directly into, which would effectively be running the kernel in practically the same way as if LILO had loaded it.
Would it be possible to actually make a Linux kernel module which did the same thing? Modules can be loaded at bootup, so it could be configured on a rooted system to load this module, which would effectively jump to a new kernel, throwing the old one out of memory.

I need to save these configurations into a file, and in my app I could change these configurations. In other words, I need a file to take all my config data, and in my app, I could read/write this file as I want.
I've searched document and mailing list archive, and have not found the exact solution. 1. SharedPreferences could not solve : It could only do with simple key/value pairs, my configuration data is more complex . 2. file in /assets , /res/raw could not solve: It seems that the file in these position would be read only
I've found a way, it almost solved my problem, but still not. Our code could deal with the file in /data/data/package-name/files on the target file system, this is good to me, but how could I put my file in this directory after my app has been installed? My app need to read these configurations when it starts.
My question is how could I pack my data file into my apk package, and then my app could read/write this file when it is run.

Is there a guide on how to do this on the web?.. if so, I haven't been able to find it.

So when updating my phone, I was all like 'I know how this show goes' and like an IDIOT I put my Samsung S2 i9100 kernel file on the bootloader spot and it boots to a black screen. I can still put it in download mode, and tried to install it the correct way but that doesn't matter.

I am launching an image picker (from the gallery) and my code crashes every single time. I tried to get some help in another post, but people quit responding to the post. Please help. When I do a debug, it tells me this (there are TONS of errors, but these looked the most important - also, I changed the "com.app.name/com.app.name.activity" for privacy reasons):

I know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file? Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

In the app I am making, I would like to take a Base64 image that is received from a server, and save it to a file for displaying later. My question is where should I store this file? It needs to be dynamic, and may be empty when the program launches. I am unsure how exactly the file system on Android works, such as how file paths look.
Ideally I would like to be able to write the data to the image file using a FileOutputStream, and then display that image somehow.
