Some modules that were supported in the old v4l-dvb source tree are not compiled by default in the new 3.0.3 kernel.

In particular, in the linux-etxx00-3.0.3/et9x00_defconfig (and also et5x00_defconfig and et6x00_defconfig) configuration file all the em28xx* modules are missing.

I suggest to add at least the following defines:

CONFIG_VIDEO_EM28XX=m
CONFIG_VIDEO_EM28XX_DVB=m
CONFIG_VIDEO_EM28XX_ALSA=m
CONFIG_VIDEO_EM28XX_RC=n
CONFIG_DVB_CXD2820R=m

The last one is the Sony DVB-T2 demodulator used in the PCTV 290e USB stick.
Since I own both an ET9000 and a PCTV 290e, I would be very happy to test how they work together.
DVB-T2 support would be a really nice feature of the new kernel :-)

[Gennar1]

By the way, when I try to add the above defines to the *defcofig file, it is always overwritten by the old configuration file:

It seems like:

scripts/kconfig/conf --silentoldconfig Kconfig

is overwriting the .config file with the original file, so I cannot compile the new modules. What I'm doing wrong?

[MiLo]

I usually do this to change (non-trivial) defconfig stuff:
- Build package up to configure level: bitbake -b ../openembedded/recipes/blahblah/blahblah.bb -c configure
- Start devshell: tmp/deploy/addons/*devshell*
- Go to work dir: cd tmp/work/machine/blahblah/blahblah/
- Run menuconfig: make menuconfig
- Save config, copy new config file back into openembedded directory
- Exit devshell (ctrl-D) and build the package: bitbake -b ../openembedded/recipes/blahblah/blahblah.bb
- Install package (or build image and/or upgrade)

[Gennar1]

TY, that worked like a charm.
I had to compile the devshell manually, as there was no tmp/deploy/addons/ dir on my build environment.
After that, using make menuconfig I added the required defines in the kernel config.
By the way, the media/video drivers were disabled altogether, so I re-enabled them.
Finally, I was able to build the missing modules.

Enough for today. Tomorrow I will test if the PCTV 290e is working with this new kernel.

[Gennar1]

This is the modified defconfig file, in case someone wants it.
I had to rename it to .txt as the file uploader does not allow to upload files without an extension, for some reason.

Next time zip it in, takes also less space and no extension issues

[pieterg]

This is the modified defconfig file, in case someone wants it.

Lets wait till you've tested your PCTV card, just in case you need more changes.

[Gennar1]

OK, I got the PCTV installed.

I had to change a few more defines in the config file: the V4L modules must be built as modules as they were not enabled by default in the original kernel:

#
# Multimedia core support
#
# CONFIG_MEDIA_CONTROLLER is not set
CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_V4L2_COMMON=m
CONFIG_DVB_CORE=y
CONFIG_VIDEO_MEDIA=y

In attachment you can find the final config file for the kernel.

In the end, the new modules built with this config file are:

kernel-module-videodev
kernel-module-v4l2-common
kernel-module-v4l2-int-device
kernel-module-videobuf-core
kernel-module-videobuf-vmalloc
kernel-module-videobuf-dvb
kernel-module-tveeprom
kernel-module-em28xx
kernel-module-em28xx-alsa
kernel-module-em28xx-dvb
kernel-module-cxd2820r

All the new modules are included in the attached zip file, in case someone wants to experiment with them.
while some other module must be installed from the OpenPli feed:

kernel-module-tda18271
kernel-module-tuner
kernel-module-tuner-simple
kernel-module-tuner-types
kernel-module-tuner-xc2028
kernel-module-zl10353

In the following posts I will report the tests done with my 2 em28xx USB sticks.

[Taykun345]

And how it works your dvb-t2 stick? Any problems?

[Gennar1]

Lets start with the brand new PCTV 290e, the first DVB-T2 capable USB stick on the market.

I connected the stick through a powered USB hub, to make sure it receives enough power. The stick works perfectly under Ubuntu 10.04 (kernel 2.6.32 with up-to-date v4l-dvb drivers).

This is an lsmod of my system before adding the new modules (since I don't need wi-fi support, I removed all the Realtech/Atheros stuff, and I installed the NFS and the SMARGO modules):

nfsd				  106907  8

modloader2			 33264  1 dvb

tpm					 7873  3 dvb,modloader2,modloader

I connected the PCTV to the ET9000, installed all the new modules and then loaded them:

modprobe em28xx-dvb

After that, the situation is:

After an enigma restart, I could select the PCTV as the third tuner.
Unfortunately, the good news ends here: I started a channel scan but no channel was found. Then I loaded a channel list made with my good old a867 stick (with the old kernel), but again no channel could be tuned (I always get a "tune failed" error).
This is consistent to the behaviour of my other em28xx stick with all kernels (2.6.18, 2.6.31 and 3.0.3).

Some errors were reported by dmesg:

[DrAk3]

hi,
can somebody provide the v4l-dvb-module-dvb-usb-af9035 for the kernel 3.0.3?

D.

[Gennar1]

I have a second em28xx stick: a TerraTec Cinergy Hybrid T USB XS (an old analog/digital hybrid tuner).

I rebooted the ET9000 with the Terratec connected, and then loaded the drivers:

modprobe em28xx-dvb

After that:

This stick needs a firmware, so I installed the v4l-dvb-firmware package.
After an enigma restart, I could select the Terratec as the third tuner. As in the previous case, the channel scan found nothing, and even installing the working channel list I could not tune anyting. This time, the dmesg did not report any error.

This behaviour is consistent with the previous kernels: I tested this stick with several images with the old drivers, on both the 2.6.18 and 2.6.31 kernels, and I've never been able to tune any channel.

If someone as an em28xx stick that was working with the old drivers, you're welcome to test the new drivers and report your experience.

[littlesat]

Did you select the European configuration at the tuner setup. By default it is on the Australian configuration and then indeed you cannot find anything during scanning...

[Gennar1]

Of course. Moreover I loaded a working channel list, as stated in my previous posts.

[ambrosa]

I usually do this to change (non-trivial) defconfig stuff:
- Build package up to configure level: bitbake -b ../openembedded/recipes/blahblah/blahblah.bb -c configure
- Start devshell: tmp/deploy/addons/*devshell*
- Go to work dir: cd tmp/work/machine/blahblah/blahblah/
- Run menuconfig: make menuconfig
- Save config, copy new config file back into openembedded directory
- Exit devshell (ctrl-D) and build the package: bitbake -b ../openembedded/recipes/blahblah/blahblah.bb
- Install package (or build image and/or upgrade)

MMhhh I'm a newbie in OE and bitbake.

Can be another solution:

1) modify openpli/openembedded/recipes/linux/linux-etxx00-3.0.3/et9xx_defconfig

2) edit openpli/openembedded/recipes/linux/linux-etxx00_3.0.3.bb and put MACHINE_KERNEL_PR_append = ".1" to force a local fresh kernel recompiling

3) run again make -d Makefile-2.1

???


I've tried this but without success: in openpli/build-et9x00/tmp/sysroots/linux-etxx-3.0.3 I have the OLD et9xx_defconfig. It looks that my new et9xxx_defconfig wasn't copy as linux-etxx00_3.0.3.bb suggest ..
What's wrong ?

[Gennar1]

I see that the new modules are now in the OpenPli repository, so everybody can try them.
My custom modules have been correctly replaced by the official one, just doing an "opkg update && opkg upgrade".
I did a quick test and they load fine, but again no channel can be tuned with my PCTV stick.

[Gennar1]

I've finally been able to make the driver working. I had to hack the driver as discussed here:

http://openpli.org/f...d-with-usb-dtt/

Those are the world first screenshots of an Enigma2 box decoding a DVB-T2 channel.
Here in my area (north-east of Italy) there is only a single DVB-T2 multiplex from Europa7 HD:

http://www.europa7.it/





Europa7 HD is not yet fully operational, so it is not encrypting the programs: everything is FTA, if you have a DVB-T2 receiver.

The patch need some work, then I will release both the patch and the kernel module, so everybody will be able to test it.
