tom-c2 Posted May 11, 2017 Posted May 11, 2017 Hello Forum, i just got my new tinker board running with armbian, thanks for the good work ! I want to set up a vdr vnsi server on this to replace the existing Raspberry 2. To get the DVB USB Skystar Tuners running several modules out of kernel/drivers/media like dvb-core and usb are needed. Are this kernel drivers already compiled available or what to do to get them ? Thanks Thomas
Igor Posted May 11, 2017 Posted May 11, 2017 If those drivers are part of a kernel, tell me which should be enabled in kernel configuration: 4.4.x: https://github.com/armbian/build/blob/master/config/kernel/linux-rockchip-default.config 4.11.x: https://github.com/armbian/build/blob/master/config/kernel/linux-rockchip-next.config or provide a patch / submit PR to our repository. If they are not part of the kernel source, then you need to obtain source (and possible firmware) and proceed this way: https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-build-a-wireless-driver
tom-c2 Posted May 11, 2017 Author Posted May 11, 2017 Hello, i think this are the first ones but then several DVB Tuner devices for USB and PCI will follow: CONFIG_MEDIA_DIGITAL_TV_SUPPORT CONFIG_V4L_PLATFORM_DRIVERS My personal interest is in USB DVB Sky Star Module first, but there may be the other modules needed by others: kernel/drivers/media/dvb/dvb-usb/dvb-usb-technisat-usb2.ko
TonyMac32 Posted May 11, 2017 Posted May 11, 2017 The default governor needs to be changed as well, the powersave setting seems to impact USB transfers pretty significantly.
tom-c2 Posted May 12, 2017 Author Posted May 12, 2017 Hello, i found this https://forum.ubuntuusers.de/topic/technisat-skystar-usb-hd-device-not-found/ and installed the media_build. Seems that this drivers aren't included in standard kernel package.
tom-c2 Posted May 12, 2017 Author Posted May 12, 2017 Hello Tony, can You please explain how the powersave settings are to be tuned ? The data rates on USB would be about 10MBit/s per Transponder and i would like to install 3 USB tuners. With 2 transponders on 3 tuners round about 60MBit/s on USB and this transferred to GBit LAN should be possible. The Raspy 2 fails with more than 4 transponders because of the slow LAN attached behind USB.
