Rebuilding the actual HF6's kernel.

Linux-SWAT · Nov 9, 2011

Oh, seems there's also an udev rule.

Linux-SWAT · Nov 10, 2011

Ok, seems almost all wifi modules are ok, i just get a

Code:

wl1251: ERROR could not get firmware: -2

I checked, it's at the good place in /lib/firmware

notaz · Nov 10, 2011

have you added that udev rule? That + compat_firmware_class.ko take care of firmware loading.

Linux-SWAT · Nov 10, 2011

Yup, i did.

This is the script i wrote and used :

Rofl, when using the defconfig from the pandora-firmware, i got a '2.6.27.4-omap1 preempt mod_unload ARMv7 ' should be '2.6.27.4-omap1-00054-g9d8c1ea-dirty mod_unload modversions ARMv7 '

Approx the same message with the OP's config.gz.

Only my custom kernel can load wifi modules. Not the firmware.

---EDIT :

Seems this is linked to modules folder's name.

fusion_power · Nov 11, 2011

When you have finished your project, what can we expect from your rebuilt Kernel? New Drivers or any improvements?

Linux-SWAT · Nov 11, 2011

http://boards.openpa...300#entry104300

Already played a lot with RAID.

I also gained ~4/5 seconds at boot.

My bluetooth mouse has a lower latency and is pretty pleasant to use.

Have UTF-8.

More filesystems support.

Etc.

Oh and the wiki's crappy kernel build instructions will be updated.

fusion_power · Nov 11, 2011

Sounds good.

How is the NTFS Support?

But there is no UTF-8 as default on the current OS? Hm, I really thought everything in there is already UTF-8 ^^"

Linux-SWAT · Nov 11, 2011

NTFS is already supported via fuse / ntfs-3g and the community codec pack.

Linux-SWAT · Nov 11, 2011

The message with the OP's config.gz is :

'2.6.27.4-omap1 preempt mod_unload ARMv7 ' should be '2.6.27.4-omap1 mod_unload modversions ARMv7 '

---EDIT :

As far as i understand, the wifi-modules are compiled for a preemptible kernel.

Trying again things, here and there, as long as i don't run out of patience.

---EDIT :

I hope wifi modules building doesn't rely on pandora-kernel ?

---EDIT :

Omg i'm such a naab, of course, i wrote a script i should have known

---EDIT :

Ok, solved the bad modules problem.

Unfortunately, even with original and firmware .configs the firmware loading problem stays the same :/

---EDIT :

Just noticed that 50-compat_firmware.rules from the official OP rootfs and the git aren't the same !

Linux-SWAT · Nov 11, 2011

Finally.

FINALLY !!!

The udev rules must NOT be copied from the /pandora-wifi/udev

Will see now if the realtek dongle is working.

Linux-SWAT · Nov 14, 2011

Dongle not working.

So, last question (i hope) :

How to build external wifi modules ?

notaz · Nov 14, 2011

There is no universal way, depends on the driver in question. Usually you need to edit the module's Makefile to point to pandora's kernel tree (instead of /lib/modules/<version>/build/ which would build for your host) and it should build.

Linux-SWAT · Nov 14, 2011

Is it the way the HF6 extra modules are built ?

I mean it's not part of the git repo ? They were added "by hand" ?

BTW i've updated the wiki.

notaz · Nov 14, 2011

It's all done by OE, see:

http://git.openpandora.org/cgi-bin/gitweb.cgi?p=openpandora.oe.git;a=blob;f=recipes/pandora-system/rtl8192u-module.bb

http://git.openpandora.org/cgi-bin/gitweb.cgi?p=openpandora.oe.git;a=blob;f=recipes/pandora-system/rtl8712-module.bb

Linux-SWAT · Dec 3, 2011

Trying compile with :

Code:

export PATH=$PATH:/usr/local/angstrom/arm/bin/

export CROSS_COMPILE=arm-angstrom-linux-gnueabi-

make clean

make ARCH=arm KLIB=../pandora-kernel KLIB_BUILD=../pandora-kerne

lFailing because it tries to compile with my host source.

Tried to use KSOURCE=... but without success :/

---EDIT :

Ans seems 8192u needs a patch ?

Use this:

Code:

make ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- KSRC=...

Linux-SWAT said:

that patch only tries to support more devices, I don't even know if it works.

Linux-SWAT · Dec 3, 2011

Worked ! Thanks - again ^^.

Will test the unpatched now on my different kernels.

I don't know where to grab the patch...

Linux-SWAT · Dec 15, 2011

Hi again.

Can't launch Quake* or N64 emulation with kernels i recompiled.

ED told me there's a 3D driver which is needed.

dimag0g · May 31, 2014

The instructions on the wiki are outdated. After the second step,

git checkout --track -b pandora-27-omap1 origin/pandora-27-omap1

I get the following errors:
