Hello
I have managed to attach the device without any error messages now but the
tuning and playback of DVB still doesn't work. I get a lot of these error
messages:
[ 247.268152] em28xx #0: reading i2c device failed (error=-110)
[ 247.268161] xc2028 1-0061: i2c input error: rc = -110 (should be 2)
and

Do anybody have an idea what to do next? Or maybe somebody is willing to help
me understanding the mcentral code because that one works fine.
Regards
Lauri

Absolutely true. Using the same pin setting as KWorld 330U made the I2C
communication work correctly and the device is found.
Now the trouble is that scanning channels doesn't work, blue LED doesn't light
up and the device is not heated up.
I'm quite newbie in this field, is there a good way to know what registers to
set exactly?
I see that the working "mcentral" code had the following setting:
#define EETI_DEFAULT_GPIO { \
.ts1_on = _BIT_VAL(EM28XX_GPIO0, 0, 0), \
.a_on = _BIT_VAL(EM28XX_GPIO1, 0, 0), \
.xc3028_sec = _BIT_VAL(EM28XX_GPIO2, 1, 0), \
/* reserved */ \
.t1_reset = _BIT_VAL(EM28XX_GPIO4, 0, 1), \
/* reserved */ \
.t1_on = _BIT_VAL(EM28XX_GPIO6, 0, 0), \
.t2_on = _BIT_VAL(EM28XX_GPIO7, 1, 0), \
\
.l1_on = _BIT_VAL(EM28XX_GOP2, 1, 0), \
.d1_reset = _BIT_VAL(EM28XX_GOP3, 0, 1), \
}
But the v4l-dvb uses:
static struct em28xx_reg_seq kworld_330u_digital[] = {
{EM28XX_R08_GPIO, 0x6e, ~EM_GPIO_4, 10},
{EM2880_R04_GPO, 0x08, 0xff, 10},
{ -1, -1, -1, -1},
};
