Hello,
I'm trying to get a dvb-t usb-stick to work with debian.
Components: em2882 - xc3028l (uses XC3028L-V36.fw) - ce6353 (zl10353) -
tvp5150 - emp202
Kernel: 4.7.0-0.bpo.1-686-pae - debian 8
i2c device: eeprom @ 0xa0 - tvp5150 @ 0xb8 - tuner(analog) @0xc2 (from
dmesg 2.6 kernel)
I got to this point:
femon -H:
FE: Zarlink ZL10353 DVB-T (DVBT)
Problem retrieving frontend information: Resource temporarily unavailable
status C| signal 71% | snr 74% | ber -1080313980 | unc -1218616323
|
Using next (G)PIO settings, enable more did not improve anything:
static struct em28xx_reg_seq zolid_tuner[] = {
// {EM2820_R08_GPIO_CTRL, EM_GPIO_4, EM_GPIO_4, 10},
// {EM2820_R08_GPIO_CTRL, 0, EM_GPIO_4, 10},
// {EM2820_R08_GPIO_CTRL, EM_GPIO_4, EM_GPIO_4, 10},
{ -1, -1, -1, -1},
};
static struct em28xx_reg_seq zolid_digital[] = {
// {EM2820_R08_GPIO_CTRL, 0x6e, ~EM_GPIO_4, 100},
// {EM2880_R04_GPO,0x04, 0xff, 100},
/* zl10353 reset ? */
{EM2880_R04_GPO,0x08, 0xff,10},
/* zl10353 to connect tuner (dmesg) */
// {EM2880_R04_GPO,0x0c, 0xff,10},
{ -1, -1, -1, -1},
};
static struct em28xx_reg_seq zolid_analog[] = {
{EM2820_R08_GPIO_CTRL, 0x6d, ~EM_GPIO_4, 10},
/* em202 (dmesg) */
// {EM2880_R04_GPO,0x04, 0xff, 100},
// {EM2880_R04_GPO,0x08, 0xff,10},
// {EM2880_R04_GPO,0x0c, 0xff,10},
{ -1, -1, -1, -1},
Two years ago I used snoop and perl tools on the ms-windows-driver and got next
result:
40 00 00 00 04 00 01 00 >>> 04, 08 or 0c
19 times alternating 08 and 0c, and the last one was 04 followed by 0c
Also 40 00 00 00 08 00 01 00 >>> 6a, 6b, 6f, 7a, 7f, fd, fe or ff
I tried all of them in the second Coulomb zolid_digital as
EM2820_R09_GPIO_CTRL, no improvement.
I do have a data-sheet em2882, did search trough linux-media and used
duck-duck-go trying to get relevant info, no luck at this point.
Question:
Where to find knowledge about the em2882 GPIO and GPO ?
And naturally, any tips or advice is appreciated.
Thanks in advance.
