由於最新LinuxTV Frontend API (tuner) 由 DVBv3 upgrade DVBv5, 原有之TVBv3 scan channel 及轉台 software用唔到 (scan command etc..) 用scan後會出現 __tune_to_transponder:1910: ERROR: Setting frontend parameters failed: 22 Invalid argument ERROR: initial tuning failed

dmesg會顯示 [34131.143241] dtv_property_cache_sync: doesn't know how to handle a DVBv3 call to delivery system 0

因而需要安裝最新之DVBv5 Tools

先移除舊dvb-tools $ sudo apt-get autoremove dvb-tools

安裝最新之DVBv5 Tools http://www.linuxtv.org/wiki/index.php/DVBv5_Tools

用 git 安裝最新版 (要先安裝幾個 Library: libjpeg-dev, libtool:, gettext etc..) 返回home cd $home $ git clone git://linuxtv.org/v4l-utils.git $ cd v4l-utils $ autoreconf -vfi $ ./configure $ make $ sudo make install

主要用以下4個commands: dvb-fe-tool : show dvbv5 frontend information dvbv5-scan : Scan dvbv5 channel dvbv5-zap : Control tuner to change channel dvb-format-convert : dvbv3 to dvbv5 files conversion tool

Dear sir, I have recently bought a d690, googling for the driver i found that you have contributed the driver source code on sourceforge. Could you be so kind to guide me through how to set up this stick on ubuntu 12.4? much appreciated. thanks

nise-designer：

看了閣下的文章後，買了Mygica D690，download了demod_rtl2840的＊.h 及*.c後，但仍未知要如何才能在13.04之下make install，可否寫一編從零開始詳細的教學文章，教教我等新丁如何才能在UBUNTU下看電視。多謝！

本編文章只講及Mygica D689及之前之DMBTH手指因Kernel 升級dvbv5之應用問題,而D690現在是沒有driver,其實呢篇文章由頭至尾都無話D690可用,不過如果想响linux睇DMBTH電視,見高登新翼有賣Contex手指($99),夠Gust可以博一博,如果試到Work可以report下：

如無意外係以前隻 Techgear
