Hi all
After some time trying to see what the problem is, I have found it is
not come the RF signal.
I've gone back using a 3.2 kernel, after doing a couple of tests, the
board works :-)
When I try to apply these changes to a 3.4 or later kernel does not tune
plate.
Between 3.2 and 3.4 kernel there are several changes to the drivers:
CX23885, xc5000 and mb86a20s. I tried to cancel several of them on a 3.4
kernel, but I can not make the card tune.
The changes I have applied to kernel 3.2 are:
In mb86a20s.c, I replaced the table "mb86a20s_init" for which I got from
windows and linux last.
With the two works, although it seems better that I got from Windows, I
have to experiment a bit more.
Also in "Does a binary search to get RF strength" I replaced 0x04 for 0x05.
On cx23885-card.c
.name = "Mygica X8507",
.tuner_type = TUNER_XC5000,
.tuner_addr = 0x61,
.tuner_bus = 1,
.porta = CX23885_ANALOG_VIDEO,
+ .portb = CX23885_MPEG_DVB,
.input = {
case CX23885_BOARD_MYGICA_X8506:
case CX23885_BOARD_MAGICPRO_PROHDTVE2:
+ case CX23885_BOARD_MYGICA_X8507:
ts1->gen_ctrl_val = 0x5; /* Parallel */
ts1->ts_clk_en_val = 0x1; /* Enable TS_CLK */
ts1->src_sel_val = CX23885_SRC_SEL_PARALLEL_MPEG_VIDEO;
break;
On cx23885-dvb.c
#include "stv0367.h"
+#include "mb86a20s.h"
+static struct mb86a20s_config mygica_x8507_mb86a20s_config = {
+ .demod_address = 0x10,
+};

+static struct xc5000_config mygica_x8507_xc5000_config = {
+ .i2c_address = 0x61,
+ .if_khz = 4000,
+};
case CX23885_BOARD_MYGICA_X8506:
case CX23885_BOARD_MAGICPRO_PROHDTVE2:
+ case CX23885_BOARD_MYGICA_X8507:
/* Select Digital TV */
cx23885_gpio_set(dev, GPIO_0);
break;
+ case CX23885_BOARD_MYGICA_X8507:
+ i2c_bus = &dev->i2c_bus[0];
+ i2c_bus2 = &dev->i2c_bus[1];
+ fe0->dvb.frontend = dvb_attach(mb86a20s_attach,
+ &mygica_x8507_mb86a20s_config,
+ &i2c_bus->i2c_adap);
+ if (fe0->dvb.frontend != NULL) {
+ dvb_attach(xc5000_attach,
+ fe0->dvb.frontend,
+ &i2c_bus2->i2c_adap,
+ &mygica_x8507_xc5000_config);
+ }
+ break;
With kernel 3.4 or greater (I also tried with the latest drivers from
git) "looking" i2c bus traffic of mb86a20s I get:

Appear not arrived RF signal.
From my limited knowledge I can not understand which of the changes
between 3.2 and 3.4 kernel affect this.
As with kernel 3.2 works, discard configuration problems of: GPIO,
signal strength, direction i2c bus and demodulator and intermediate
frequency. I am right?
Any suggestions or help is very welcome.
Thanks in advance,
Alfredo
