[linux-dvb] Re: dvbd

[Holger Waechtler]

Hi,

I don't know exactly what you are using there, but this is definitely not the current driver from CVS. Please get a recent driver by tapping

$ cvs -d :pserver:[EMAIL PROTECTED]:/cvs/linuxtv login
[press enter]
$ cvs -d :pserver:[EMAIL PROTECTED]:/cvs/linuxtv co DVB
$ cd DVB
$ make

then

$ rm modules/2.4.19/kernel/drivers/media/video/dmxdev.o

and remove all other old driver files

then try as root:

$ cd driver
$ ./makedev.napi

to create the device nodes. To load the driver:

$ make insmod

Then try to tune using szap and test if you can get a lock. I don't know if dvbd is maintained anymore, report problems related to dvbd to the author.

Holger

ok now I tried patch-8
on modprobe dvb I see
Warning: loading /lib/modules/2.4.19/kernel/drivers/media/video/dmxdev.o
will taint the kernel: no license

This is a normal message when the kernel does not detect the license
information from the modules. Apparently Rolf forgot to add the license
information defines in all modules. Not ot worry, this has no effect on
the working of the modules.

2.4.19

I am guessing here, but have you tried a 2.4.18 kernel and dvb ?
I know 2.4.5 had many wierd problems, and I already heard some roumors
about 2.4.19.
I'd give it a try with the stock 2.4.18 from the slack8.1 kit.

Module dvb loaded, with warnings

module dvb should load without warning about license as it correctly
defines the license informaiton. Check the source.

everything is the same but in syslog I see now more:
dvbd[2662]: ioctl VIDIOCGCAP (dvbd.c, 1335): Unknown error 515 -

aborting

Check the source, this is generated at:
       /* check if DVB card/driver is present at opened V4L device */
There is a serious problem with detecting your card here.
I'd start turning on debugging on the modules and dvbd.

videodev in module with major (from the install of patch-8)
alias char-major-81         videodev

videodev from kernel (only videodev configured in the kernel at video
for linux) loaded correctly I assume.

Check the changelogs between 2.4.18 and 2.4.19 that may concern i2c,
videodev.

Something seems to be seriously wrong between your kernel, drivers and
card.
Have you tried to set debugging in turn with each module and load them
manually? especially dvb.o? and keep high debuging on dvb.o while trying
to load dvbd?

Have you tried to compile and use the gVideo app to see if you can
receive mpeg video from the satellite? If that doesn't work with various
warnings, errors, there is a problem somewhere.
Eutelsat W3 should have at least some polish stations with high SR that
are visible with small dishes. If not, try Hotbird.

What pcb revision is your card? (see card for Rev 1.5 or Rev 2.1 or
similar).
Could you please run dumpee and post the result so I can compare it with
mine? (I also have a Skystar 1 rev 1.5)
