Hi,

 

I have very popular DVB-C/T/T2 astrometa USB stick. There is no official driver from Astrometa for this device for linux, anyway it worked partialy with dvb-usb-rtl28xxu driver, only DVB-T1, not C/T2. Thanks to some good people reverse engneering was done and now there is support for MN88472/3 and T2/C works fine.

 

 

Components:
Realtek RTL2832P
Panasonic MN88472 (newer version MN88473)
Rafael Micro R828D

I have linux Ubuntu 12.04lts and I have tried it out my self, compiled drivers for Kernel 3.13 and scan the services.

 

 

I have DM800 and I would like to have drivers for it, but I have never build anything for E2 (mipsel) before, so I need help how if it is possible to port it for kernel 2.6?!

 

The driver author recomended me this:

./build --git git://linuxtv.org/anttip/media_tree.git astrometa

And link:

http://linuxtv.org/w..._Device_Drivers

 

But if I do so, would I again build modules for my architecture and ubuntu kernel, not mips?

Setup a build environment for your box with devshell.

Then start devshell and build drivers under OE for your box.

[malakudi]

I doubt you could backport the drivers to 2.6.18 that DM800 uses. You could have more success with some newer box.

[pieterg]

dvb-usb has been completely rewritten (several times) since then, so you'll have a really hard time backporting

[amm8990]

What about for newer devices (kernels) example, DM500, DM800SE?

[pieterg]

I think these use some 3.x kernel nowadays?

Less work, but still you need to do some backporting (usb-dvb-v2 is probably missing)

I think using mediabuild you can actually build more drivers than your kernel supports.

I was able to compile drivers using mediabuild for dm800se but due to lack of time I abandoned this project.

I am sure that requires also changes to kernel (you must not compile some "dvb related" into kernel but make those modules)

Also I thinkg that some popular images are using this technique (eg blackhole).

@amm8990, go ahead, give a try (but you are on your own...)

PS. I'll my notes in case I had something written down.

dm500hd, dm800se use linux kernel 3.2 . Quite old also. 

[athoik]

The LinuxTV V4L-DVB drivers will work only in conjunction with relatively modern 2.6 kernels; specifically 2.6.31 and up.

[malakudi]

You are right, 3.2 is still supported. So he might succeed with DM800SE or DM500HD.

We assume that openpli4 is installed under /opt/openpli4/ and box is dm800se...

cd /tmp

git clone --depth=1 git://linuxtv.org/media_build.git
cd media_build

ARCH=mips \
CROSS_COMPILE=/opt/openpli4/build/tmp/sysroots/x86_64-linux/usr/bin/mipsel-oe-linux/mipsel-oe-linux- \
DIR=/opt/openpli4/build/tmp/sysroots/dm800se/usr/src/kernel/ \
make cleanall

ARCH=mips \

make menuconfig

### Choose what you need here (eg Enable drivers not supported by this kernel (NEW) and disabled modules not required eg Analog TV support, AM/FM radio receivers/transmitters support, Software defined radio support, Media PCI Adapters, GSPCA based webcams, USB Philips Cameras, USB ZR364XX Camera support, USB Syntek DC1125 Camera support, USB Sensoray 2255 video capture device, USBTV007 video capture support, Sensors used on soc_camera driver, Media test drivers, Remote controller decoders, Remote Controller devices)

ARCH=mips \
CROSS_COMPILE=/opt/openpli4/build/tmp/sysroots/x86_64-linux/usr/bin/mipsel-oe-linux/mipsel-oe-linux- \
DIR=/opt/openpli4/build/tmp/sysroots/dm800se/usr/src/kernel/ \
make -j 4

Under v4l folder you have the modules compiled, most probably you have to compile kernel dvb-core (and some others) as module in order to be able to use v4l modules.

Good luck!

Thanks a lot athoik for your notes  

The next week i try to compile the driver by myself for my solo2.

Then i give my feedback here...

[jbnl]

Hopefully this will also work on the ET9000, that would be great. And then DVB-C support.

Kernel is there 3.8.7.

 

Did you buy this stick on Ebay ?

Thank you @athoik

 

Driver for MN88473 (not sure for MN88472) already support DVB-C, see picture, the scanned programs are DVB-C. I bought the stick from dx (dealextreme), take care if you are buying to take newer improved version with MN88473 demodulator.

Hi, i bought the tuner yesterday on ebay and i don't known which model...

Do you known if the 88472 support t2 and dab? I'm not interesting to dvb-c.

The next week i will try to compile the driver (with fingers crossed)

[amm8990]

Hi,

 

Not sure about 88472, you need to ask the author http://blog.palosaar...mdvb-t2-v2.html

Hi amm8990,

 

The stick you bought is that the same as the picture ? That stick has the 88742 chipset if i read correctly the blog from Palosari.

[amm8990]

The case is old, but the hw is the new one 88743, so don't judge only by the case.

[dax]

The only differencies that i can see from Antti' s blog is (besides the case):

for 88743

lsusb -vvd 15f4:0131
...
  iManufacturer           1 astrometa
  iProduct                2 amdvbt2

and for 88472

lsusb -vvd 15f4:0131
...
  iManufacturer           1 astrometadvbt2
  iProduct                2 dvbt2

Same usb id for both devices but different manufacturer and product.

So, as amm8990 said, i can't judge by the case but i bought the same of the picture above. I will have to wait...

[jbnl]

Aha oke clear.
