Re: Help to make a driver. ISDB-Tb
Hi Digital television: not tune any channels with w-scan or gnome-dvb-setup. But with the latter, it captures 2 weak signals, but I can not know which is. Under windows also capture 2 channel and I'm in a place where the signal is low. I'll try to have more signal strength. If I run dmesg after scan channels I get the following: [ 3474.858537] mb86a20s: mb86a20s_set_frontend: [ 3474.858541] mb86a20s: mb86a20s_set_frontend: Calling tuner set parameters [ 3474.981157] mb86a20s: mb86a20s_read_status: [ 3474.981649] mb86a20s: mb86a20s_read_status: val = 2, status = 0x01 I improved the antenna signal and I've got this: alfredo@linux:~ mplayer -dumpstream dvb://'C5N HD' -dumpfile mplayer-dumpfile.ts MPlayer dev-SVN-r33321-4.5-openSUSE Linux 11.4 (x86_64)-Packman (C) 2000-2011 MPlayer Team Can't open joystick device /dev/input/js0: No such file or directory Can't init input joystick mplayer: could not open config files /home/alfredo/.lircrc and /etc/lirc/lircrc mplayer: No such file or directory Failed to read LIRC config file ~/.lircrc.

From this message:
[ 14.288626] Frontend revision 255 is unknown - aborting.
I suspect that the I2C gate needed to access the frontend is at the wrong
state. That's why you're
getting 0xff (255) value there.
I reiterate my gratitude,
Alfredo

Hi Mauro
Thank you very much for your time and answer

You forgot to declare this constant somewhere with #define.
I found it. I had written CX23885_BOARD_MYGICA_X507 rather than
CX23885_BOARD_MYGICA_X8507 in cx23885.h
It is not that simple. You need to setup the GPIO pins of your device, and
set the DVB frontend according to how this is wired inside the board,
and providing the information about the used frontend. I think that your
device is based on mb86a20s demod.
Yes.
If I compare to the X8506 images taken from
http://www.mingo-hmw.com/forum/viewthread.php?tid=85682 and
http://www.dcfever.com/trading/view.php?itemID=436551, with the X8507
taken from
http://www.linuxtv.org/wiki/index.php/File:MyGica_X8507_1.png; I see
that the difference is on the plate added to the main board. Best viewed
with the image of the X8507 and corresponds to the frontend.
For this last reason is that I risk trying to do something.
It requires you some knowledge about Engineering

At this point yes. The last time I programmed anything was more than
twenty years and was in pascal or qbasic, I do not remember.
