Building crazycat's media_build on RPi3

Sat May 25, 2019 8:52 am

Hello,

I am trying to make DVB EVOLVEO SIGMA T2 working.
Linux can see it as ID 0572:c68a Conexant Systems (Rockwell), Inc.

so I tried to use Crazycat's media-build

Code: Select all

sudo apt-get install raspberry-kernel-headers
sudo apt-get install libproc-processtable-perl git build-essential
git clone https://bitbucket.org/CrazyCat/media_build.git
cd media_build
./build.sh
sudo make install
This works well at desktop computer with Ubuntu. But not in recent Raspbian Lite.
It compiles and install without errors, but when I re-insert the device, /var/log/messages says that there are some problems with modules version.

Did anybody compile it on Pi3?

Hi, I am really happy that someone else has this tuner. Evolveo is a private brand of Czech company Abacus. Aren't you from Czech republic? Anyway tuner is rebranded Geniatech T230C2. Few months ago I have managed it to work with Orange Pi/Armbian. It was really painful and very time consuming. But now it works. My progress was similar to yours.

Code: Select all

apt install patchutils linux-headers-next-sunxi
sudo apt-get install git build-essential libproc-processtable-perl
sudo apt-get install dvb-apps dvb-tools w-scan vlc
git clone https://bitbucket.org/CrazyCat/media_build
cd media_build
./build
sudo make install
sudo make rmmod
sudo modprobe dvb_usb_cxusb
I also needed to charm with kernel version and it works with 4.20.12 for Armbian. But you may try

Code: Select all

sudo make rmmod
. It is the only difference in yours and mine process. Just now I am trying to make it work on rpi3, so I will give you a feedback.

I didnt know it about Evolveo.
Yes, I am from Prague.

This tuner is better in sensitivity than the PI DVB Hut and the most TVs

Greetings from Budweis ;-). Yesterday I have tried to compile drivers on latest raspbian full. I had to do some excercises with kernel versions before it finally compiled. But it still does not work. It sais

Code: Select all

[   82.794694] dvb_usb: disagrees about version of symbol rc_register_device
[   82.794711] dvb_usb: Unknown symbol rc_register_device (err -22)
[   82.794828] dvb_usb: disagrees about version of symbol rc_free_device
[   82.794836] dvb_usb: Unknown symbol rc_free_device (err -22)
[   82.794946] dvb_usb: disagrees about version of symbol rc_allocate_device
[   82.794953] dvb_usb: Unknown symbol rc_allocate_device (err -22)
[   82.795171] dvb_usb: disagrees about version of symbol rc_unregister_device
[   82.795178] dvb_usb: Unknown symbol rc_unregister_device (err -22)
and when I try modprobe

Code: Select all

modprobe: ERROR: could not insert 'dvb_usb_cxusb': Invalid argument
I am very happy, that on orange pi pc I somehow managed it to work. But I would like it to work on rpi too.
About sensitivity - I have very good DVB-T signal, so I can not compare. But RPi TV Hat works out of the box. This USB crap is a pain. This evening I will give it another try. I would like to use RPI with T230C2 as tvheadend and opi as TV box with kodi.

Same result here. Lot of 'disagrees about version of symbol ...' in DVB stuff.
Maybe there are some differences between version of kernel and the headers.

I tried this both with pre installed kernel and with update && upgrade (which installs a bit newer kernel). With the same results.

Yes, I agree. I will try older raspbian and post results.
