Installation drivers for DigitalDevices and TBS DVB adapters
DigitalDevices Driver Installation
Run in console:
curl http://cesbo.com/download/astra/scripts/drv-dd.sh | bash
Installation in manual mode
Prepare system
To install drivers needed root privileges:
sudo -s
Install system utilities to build drivers from the source code:
apt-get install build-essential \
patchutils \
libproc-processtable-perl \
linux-headers-$(uname -r) \
git
Remove old media drivers:
rm -rf /lib/modules/$(uname -r)/extra
rm -rf /lib/modules/$(uname -r)/kernel/drivers/media
rm -rf /lib/modules/$(uname -r)/kernel/drivers/staging/media
Disable auto update in Ubuntu 16.04
systemctl disable apt-daily.service
systemctl disable apt-daily.timer
Install
Download latest driver from the official repository:
git clone --depth=1 https://github.com/DigitalDevices/dddvb /usr/src/dddvb
cd /usr/src/dddvb
By the default driver has limit only for 8 DVB adapters. Remove this limit before build drivers:
sed -i \
-e 's/^#if defined(CONFIG_DVB_MAX_ADAPTERS).*$/#if 0/g' \
dvb-core/dvbdev.h
If you have more than 64 adapters (for example 10 MaxS8) need to increase limit in the driver:
sed -i \
-e 's/DVB_MAX_ADAPTERS 64/DVB_MAX_ADAPTERS 256/g' \
dvb-core/dvbdev.h
sed -i \
-e 's/^\(#define MAX_DVB_MINORS*\).*/\1 512/g' \
dvb-core/dvbdev.c
Build drivers and install it:
make
make install
Create a list of module dependencies:
mkdir -p /etc/depmod.d
echo 'search extra updates built-in' >/etc/depmod.d/extra.conf
depmod -a
Create configuration file for MaxS8 DVB adapters:
echo 'options ddbridge fmode=X' >/etc/modprobe.d/ddbridge.conf
Replacing X with the mode number.
Modes for Max S8 :
fmode=0
4 tuner mode ( Internal multiswitch disabled )
fmode=1
Quad LNB / normal outputs of multiswitches
fmode=2
Quattro - LNB / cascade outputs of multiswitches
fmode=3
Unicable LNB or JESS / Unicabel output of the multiswitch
To launch installed drivers restart your system:
shutdown -r now
After reboot check adapters:
ls /dev/dvb
Should be listed all adapters installed in the system:
adapter0 adapter1 adapter2 adapter3 adapter4 adapter5 adapter6 adapter7
Troubleshooting
Signal is fine, but channels don't work
Check dmesg output for i2c errors:
dmesg | grep i2c
if you see messages like i2c_write error then turn off MSI (Message Signaled Interrupts) in the driver:
Open /etc/modprobe.d/ddbridge.conf
in any text editor
Find options ddbridge … line
After the ddbridge append msi=0 option. For example: options ddbridge msi=0 fmode=1
If file does not exists, then create it and write:
options ddbridge msi=0
DVB adapters are not available
If ls /dev/dvb shows error:
ls: cannot access /dev/dvb: No such file or directory
With lspci you may check is adapters available in the system:
lspci | grep Multimedia
If adapters connected to the PCIe properly you will see listing of the PCIe adapters. For example:
01:00.0 Multimedia controller: Digital Devices GmbH Cine V7
Check system boot log for errors:
dmesg | grep -i dvb
You may send this log to the adapter vendor to find a solution.
Drivers has been installed some time ago and all worked fine before server reboot
Probably Linux kernel has been updated. After Linux kernel update drivers should be reinstalled.
TBS Driver Installation
Run in console:
curl http://cesbo.com/download/astra/scripts/drv-tbs.sh | bash
Installation in manual mode
Prepare system
To install drivers needed root privileges:
sudo -s
Install system utilities to build drivers from the source code:
apt-get install build-essential \
patchutils \
libproc-processtable-perl \
linux-headers-$(uname -r) \
git
Remove old media drivers:
rm -rf /lib/modules/$(uname -r)/extra
rm -rf /lib/modules/$(uname -r)/kernel/drivers/media
rm -rf /lib/modules/$(uname -r)/kernel/drivers/staging/media
Disable auto update in Ubuntu 16.04
systemctl disable apt-daily.service
systemctl disable apt-daily.timer
Install
Downloading and building:
cd /usr/src
git clone https://github.com/tbsdtv/media_build.git
git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media
cd media_build
make dir DIR=../media
make allyesconfig
make -j4
sudo make install
Install firmware for DVB adapters:
curl -L http://www.tbsdtv.com/download/document/linux/tbs-tuner-firmwares_v1.0.tar.bz2 | tar -jxvf - -C /lib/firmware/
To launch installed drivers restart your system:
shutdown -r now
After reboot check adapters:
ls /dev/dvb
Should be listed all adapters installed in the system:
adapter0 adapter1 adapter2 adapter3 adapter4 adapter5 adapter6 adapter7
