Hi all,
Something very strange:
If in saa7134-dvb.c I do this:
<snip>
static int configure_tda827x_fe_kw210(struct saa7134_dev *dev,
struct tda1004x_config *cdec_conf,
struct tda827x_config *tuner_conf)
{
dev->dvb.frontend = dvb_attach(tda10046_attach, cdec_conf,
&dev->i2c_adap);
if (dev->dvb.frontend) {
/* if (cdec_conf->i2c_gate)
dev->dvb.frontend->ops.i2c_gate_ctrl = tda8290_i2c_gate_ctrl; */
if (dvb_attach(tda827x_attach, dev->dvb.frontend,
cdec_conf->tuner_address,
&dev->i2c_adap, tuner_conf))
return 0;
wprintk("no tda827x tuner found at addr: %02x\n",
cdec_conf->tuner_address);
}
return -EINVAL;
}
<snip>
case SAA7134_BOARD_KWORLD_DVBT_210:
/* if (configure_tda827x_fe(dev, &kworld_dvb_t_210_config, */
if (configure_tda827x_fe_kw210(dev, &kworld_dvb_t_210_config,
&tda827x_cfg_2) < 0)
goto dettach_frontend;
break;
<snip>
then I can scan all available DVB-T channels, and view them.
If I leave it as original, it won't scan/view SBS.
Can someone tell me what part does this play?
if (cdec_conf->i2c_gate)
dev->dvb.frontend->ops.i2c_gate_ctrl = tda8290_i2c_gate_ctrl;
I use this:
# Australia / Perth (Roleystone transmitter)
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
# SBS
T 704500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
# ABC
T 725500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
# Seven
T 746500000 7MHz 2/3 NONE QAM64 8k 1/16 NONE
# Nine
T 767500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
# Ten
T 788500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
Regards,
Timf
