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},
};

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

[  433.232124] xc2028 1-0061: Loading SCODE for type=DTV6 ATSC OREN538 SCODE HAS_IF_5580 (60110020), id 0000000000000000.
[  433.256017] xc2028 1-0061: Incorrect readback of firmware version.
[  433.372019] xc2028 1-0061: Loading firmware for type=BASE F8MHZ (3), id 0000000000000000.
[  437.940029] xc2028 1-0061: Loading firmware for type=D2620 DTV78 (108), id 0000000000000000.

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

Due some fundamental problems we do not recommend to use the
em28xx-new code, it can damage your device(!)

We are now working together with several manufacturers since we
accepted their restrictions we got indepth details about how to handle
those devices correctly in order to prevent damaged devices. Even if
it works fine for you it might break the device the next day. The only
way to get it right is to cooperate with the chip design companies.

Hi

Sorry if I wasn't clear enough. I'm trying to get V4l code working. So I'm playing around with GPIO's and have managed to get the I2C communication working but something is still missing. I was thinking that because mcentral code worked, maybe some information can be taken over from it but the code is so much different, I do not understand it fully.

Or what should I try next?

Lauri
