Module Usbcore.o Not Available. Why?

[magickarle]

Hi, I'm trying to get a CFU1 usb host workinf on my poodle.
Here's my logread:

So I don't know why it says module usbcore not found.
It's trying to get a "module /lib/modules/2.4.18-rmk7-pxa3-embedix/pcmcia/usbcore.o" with a error "not available" but this file is in /lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/usb/device so I did a copy to "/lib/modules/2.4.18-rmk7-pxa3-embedix/pcmcia" but it still says not available
Man, this zaurus is driving crazy!
Here what I've done:
reinstaled cfu1-driver_0.0.2-3_arm.ipk
installed from feed machine/poodle kernel-module-usbdcore_2.4.18-rmk7-pxa3-embedix-r36_poodle.ipk

Any help would be apprecated.Thanks

usbcore and usbdcore are different things - usbdcore is what allows ethernet over usb iirc.

You probably need to modify the defconfig for your machine to enable usb (you may also need a minor patch - I sent the defconfig and patch for the Shepherd to the OE mailing list a long time agao, that should get you started looking in the right place).

Great. thanks. I'm a newbie n not sure how to modify defconfig n neither to get the oesf mailing list.
I did some research on google and on this site about those but I didn't get much info.
Any links or more info about how to modify defconfig?
Thanks

[lardman]

You'll need to modify your defconfig file (called defconfig-poodle in packages/linux/openzaurus-pxa_2.4.18-rmk7-pxa3-embedix20031107 I think) to add the appropriate lines - see my shepherd patch, then patch the kernel (see below) re-build the kernel so that usbcore is built.

I submitted the driver for the REX-cfu1 usb host CF card earlier today. It needs the usbcore.o module to run.

I have modified the defconfig-shepherd (via make menuconfig) to produce some USB related modules (I just went through and clicked on anything that looked interesting). The patch is here:
http://students.bath.ac.uk/enpsgp/Zaurus/d...g-shepherd.diff

The kernel also needs a patch to remove an ifneq check I'd guess comes directly from the Sharp code, otherwise usbcore.o isn't built.

Lines 45-47 of drivers/usb/Makefile are as follows:

ifneq ($(CONFIG_ARCH_SHARP_SL),y)
obj-$(CONFIG_USB)  += usbcore.o
endif

To make usbcore build I simply removed the ifneq/endif from around the middle line.

Patch here: http://students.bath.ac.uk/enpsgp/Zaurus/e...e-usbcore.patch

I don't know why this ifneq is in there, and hopefully this patch won't break anything (the kernel and modules all built correctly, but I've only tested the usbcore.o module).

Cheers,

You'll also need to build cfu1 for your kernel/machine combo. This is in OE:

Builds, and works fine on my Shepherd.

Requires usbcore.o (kernel-module-usbcore) to run (this is in the bb as an RDEPENDS), defconfig patch and kernel patch to follow to create this module as part of openzaurus-pxa_2.4.18-rmk7-pxa3-embedix20031107.bb

So I need to recompile a new kernel with usbcore "enabled" right?
Any good "how to" about this recompile process?
thanks alot

[lardman]

Get OE setup (see http://openembedded.org -> wiki -> GettingStarted), then I'll run you through it,

[magickarle]

Hi, I did it.
So...  what's next? It seems that a lot of people needs those steps. Asa I'm finished with it, I'll post the new rom with usbcore module for the 5600

I'm glad you've got it sorted - you don't need to post an entire 'ROM', just the ipks for the kernel modules will be enough for others to install and use.

No it's not sorted out, I just need the other steps that you were talking about.

[lardman]

Ah, sorry, I mis-understood.

So you have OE setup and working fine? Have you built something to test that it's working okay (try 'bitbake virtual/kernel')

Now you want to build the kernel modules & build the cfu1 driver I take it?

Yes, that's right, I'm not too sure where to start for the built of kernel n module.

[lardman]

'bitbake virtual/kernel'

should build the correct kernel for your machine.

Then just do

'bitbake cfu1'

Which will build the cfu1 drivers.

Then you'll need to look in the packages/linux/openzaurus-pxa-2.4.18-rmk7-pxa3-embedix20031107/ directory and alter the defconfig-poodle in there.

I would first cd to the kernel build directory in tmp/work/* and run the following to choose the kernel options you want (this has to be done after you build the kernel of course).

export ARCH=arm
make menuconfig

Then select the various usb drivers which you want, and either replace the defconfig file (see above) with the .config file in the kernel source directory, or look in it and add the extra parts to the defconfig file.

Then you need to make bitbake rebuild the kernel - run 'bitbake -c clean virtual/kernel', then run 'bitbake virtual/kernel' again and it should make your usb modules.

Hope that made some sense,


Si
