problem with 'init'

Gyorgy Kovesdi — 2012-05-23T13:46:07

Hi,

I have a Beagleboard C4

I tried to build systemd-gnome-image by Narcissus and on my machine too. Some other
packages are tried as well with the same result, but i would like to use this one.
Using the latest version i have problem with 'init'. I found that no init scripts are executed (at lest
for levels 3 and 5) and therefore e.g. the X is not started after boot.
Executing 'init 5' or 'init 3' does nothing. However, 'init 0' and 'init 6' are work as expected.
I have the file '/etc/inittab' , but its content is also ignored.
I can start the X by executing '/etc/init.d/gdm start'. However, its link in /etc/rc5.d/ is also ignored
by init.

How can i build working init?

Thanx in advance
Gyorgy Kovesdi

Re: USB OTG not working for linux-mainline-3.2 (was Problem with usbhid kernel module)

This relates to usb code changes committed July 2011.  As a result of 
these chages a gadget driver must be loaded in order for host mode to be 
activated.  If you load a gadget driver, then host mode should be activated.

I forgot about an important detail: my USB is working, devices other than mouse and keyboard
are functional, it is only a module insertion problem. I don't know where the module 'usbhid'
should be inserted, so IMHO it is an Angstrom-related problem.

Hello,

I just tested your kernel workflow
I have modified the em28xx-core.c file (in 
kernel....drivers/media/video/em28xx/ )
after the -c compile and -c build, I see that the em28xx-core.o has not 
been updated

finally, i ran the command    bitbake -b linux-mainline_3.2.bb
compilation is not finished now, but as far as I see, the module (.ko) 
is up to date

This solution seems to be working for what I need (module-only 
recompilation)
Now, I will test your suggestions to reconfigure the kernel

Thanks to you all for your help !
Best Regards,

Chris

Problem with usbhid kernel module

Gyorgy Kovesdi — 2012-05-23T08:16:22

Hi,

I have a Beagleboard C4, using it with USB keyboard and mouse.
Building the current version of Angstrom results a non-functional keyboard and mouse at the first boot.
After some digging, i found that the kernel module "usbhid" is not compiled in. It is built as a module (m), but
is not loaded during startup. Some weeks ago, it was compiled in (y) in the default kernel config of Beagle.

This way the only possibility to get it working is to log in using the serial port, and set up manually.
I think it is related to other Beagle boards (e.g. xM), however, other people reported that it is working. Do they
use it other way, or do i made something wrong?

You are right, bitbake -f -c compile virtual/kernel leaves the sources 
in place (with my modifications)
But I cannot find the module (em28xx.ko) file with a recent date&time. 
It seems it is not rebuilt.
I think another approach is to get a pure kernel from kernel.org, apply 
the patches, overwrite the .config and "make uImage modules"
I will try this !
thanks anyway for your help !

Re: compiling a kernel module

Bob Feretich — 2012-05-22T19:17:08

I generally do my kernel builds in 3 steps (steps 3-5). (5 steps for the 
first time)
The kernel is built when Angstrom builds, but sources are deleted. I 
like the source available for examination and want to be able to easily 
reconfigure the kernel.

 1. bitbake -c clean virtual/kernel          // ready OE to rebuild the
    kernel
 2. bitbake -f -c compile virtual/kernel   // execute the OE build up to
    the compile step
 3. cd ....../git
    make menuconfig                             // edit the kernel
    configuration
 4. bitbake -f -c compile virtual/kernel   // force re-do of the compile
    step with the new config settings
 5. bitbake  -c build virtual/kernel          // execute the OE steps
    after the compile, but don't erase
                                                            //     
    intermediate results (kernel sources)

With the intermediate results left intact, I can easily build driver 
modules independently for testing.
bitbake  -c build -b <my driver recipe .bb>
(Generates a .ko file that I can load with insmod.)

Bob F.

When you are done modifying your code could you not just run
bitbake -f -c compile virtual/kernel ?
I have not messed with kernel modules other than changing the config. By 
doing the -f -c compile , if I am correct should only force a compile of 
virtual/kernel again leaving the modifications in place.
Hopefully a bitbake/OE master will chime in the actual proper commands 
to do exactly what you wish.

Re: compiling a kernel module

chrbruno — 2012-05-22T17:41:29

Thanks for your reply,

in fact, I use the virtual/kernel as a target
I don't know what name to provide for "YourModule"
The module I work on is driver/media/video/em28xx but "em28xx" is not 
recognized as a target by bitbake

when I run a bitbake -c clean virtual/kernel, it removes all the kernel 
and module sources (the source code I want to modify)

I think I will dig into the OE documentation !
or another approach would be to get the .config/patches  from angstrom 
tree, and compile a pure kernel using the classical "linux" method

Best Regards,
Chris

Is there a _full_ list available about the possible options? There are
a lot of pages on the net with particular solutions, but such a list

Re: compiling a kernel module

Don deJuan — 2012-05-22T16:10:37

I could be wrong here but I believe if you use
bitbake -c cleansstate YourModule
Is the better way to clean the package. I was having issues just using 
clean and no long do when I do the cleansstate.

Re: compiling a kernel module

Gyorgy Kovesdi — 2012-05-22T13:08:58

I had similar problem: if you compile something like this:
$> bitbake your-module
then executing
$> bitbake your-module -c clean
theoretically would be enough for recompile it next time. But i found this is not enough in
some cases (e.g. for kernel modules), i don't know why.
Try to clean the state cache this way:
$> rm build/sstate-cache/*your-module*
Hope this helps

Information about angstrom version to use withopenembedded

2012-05-22T12:04:27

Hi all,
I hope this is the right place to ask. I've checked the FAQ and
searched on the internet but I didn't find an answer.
I've downloaded a rootfs image from narcissus for "beagleboard" based
on 2011.03 release. SDK is named "Angstrom-2012.05...". In
Openembedded/bitbake "build/conf/local.conf", which version named
"angstrom-20yy.m" I have to use? I have tried both of them but bitbake
fails to build every package.
Thanks

compiling a kernel module

chrbruno — 2012-05-22T10:56:49

Hello (I'm new to angstrom),

I'm working on a kernel module on Beagleboard / Angstrom but I can't 
find a way to modify and recompile it

I followed the procedure on 
http://www.angstrom-distribution.org/building-angstrom
It generates correctly the kernel and rootfs

To keep the sources, i have removed the line INHERIT += "rm_work" from 
my conf/local.conf

The problem is that I cannot find a way to recompile this kernel module

I used :
bitbake virtual/kernel -c compile -f
... but i cannot find the module on disk, or it is not recompiled
( I work on 
setup-scripts/build/tmp-angstrom_v2012_05-eglibc/work/beagleboard-angstrom-linux-gnueabi/linux-mainline-3.2.16-r120d/git/drivers/media/video/em28xx/em28xx.ko 
)

I am missing something ?
Your help would be greatly appreciated

Best Regards,

Chris

Please provide the error messages before these lines, it says nothing.
I had problems about it too, and the solution was installing the package glibc-static on the host machine. But it is just a guess.
Hope it helps

I'm not sure why you're having troubles and I do not.  An indication  of
how you built, etc (especially since you have a very different kernel than I do)
would be useful.

Perhaps you could provide your actual image files?  I could then try
those exact images on my hardware & see what happens. note: I can provide
you an FTP drop point if that makes things easier (email me directly)

All,
I followed the posting of Kövesdi György

git clone git://github.com/Angstrom-distribution/setup-scripts.git
I get a different error.
ERROR: '/home/vidal/angstrom/setup-scripts/sources/openembedded/recipes/module-init-tools/module-init-tools-cross_3.12.bb' failed
I did bitbake -k x11-image & bitbake -k and they both fail

Is the sysroot just what needs to go to the linux partition since I did not get a bz2 file.

Thanks

If retrying succeeds, then it means temporary connection problem, it happens sometimes for me too.
Other problem can be using obsoleted sources. Usually it happens with Debian sources (ftp.debian.org)
due to frequent content change. IMHO using Debian sources should be avoided. :-)
