With SAA7127 loaded there's no problem (actualy there are no syslog
messages at all when switching channels).
Setting the no_black_magic parameter nonzero will get rid of that i2c write.
Interesting though, I think everyone has just assumed that write was
necessary to power up the PAL cards (as per Ulf's note)... Maybe it's
(at best) superfluous for everyone.
Hu ?! Not only for PAL, also for Secam
There is NO saa7127 on my secam pvr150 BUT why do i need it to have secam tuner working...
I'm trying to make my pv150 work (secam mode), kernel 2.6.11-rc5 / ivtv 0.3.2f
I found that i can have sound or video from tuner, but not both...
Here is the script i use to test :
============================================================================
#!/bin/sh
modprobe ivtv ivtv_std=3 tuner=38 tda9887=0 rmmod ivtv rmmod wm8775 cx25840 tuner videodev tda9887
modprobe tveeprom sleep 1
modprobe saa7127 sleep 1 #if i load saa7127 after cx25840 => then i've sound but scrambled image... #loading this module before is required to have tuner video ok ?!
modprobe cx25840 i2c_enable=1 debug=1 sleep 1
modprobe wm8775 debug=0 sleep 1
modprobe tda9887 secam=l sleep 1
modprobe ivtv ivtv_std=3 tuner=38 tda9887=0 sleep 1
#here i've video from tuner working but no sound (saa7127 loaded) ivtvctl -d /dev/video0 -c bitrate=4800000 ivtvctl -d /dev/video0 -u 0x7F0000 ptune.pl --frequency 847250 --tuner-num 0 dd if=/dev/video0 of="/myth/video.mpeg" bs=1024 count=10k
rmmod ivtv rmmod wm8775 cx25840 tuner videodev tda9887 tveeprom saa7127 modprobe ivtv ivtv_std=3 tuner=38 tda9887=0 ivtv_debug=255
#here i've tuner sound working but scrambled image (saa7127 not loaded)
ivtvctl -d /dev/video0 -c bitrate=4800000
ivtvctl -d /dev/video0 -u 0x7F0000
ptune.pl --frequency 847250 --tuner-num 0
dd if=/dev/video0 of="/myth/sound.mpeg" bs=1024 count=10k
