Yes, i try to change probing code and the module found a tuner at e1... the analog tv seems work.Gabriele Verzeletti wrote:Hi. I'm trying to make my "pinnacle pctv310i" work.I noticed many are managing to do the same, so I decided to share the results I've been able to obtain so far.At the moment only non-digital TV signal works.On the card are the following components: TDA8275A Tuner, SAA7131E decoder and a TDA10046A decoder for earth digital signal. In order to pilot the tuner I had to change the I2C_SCAN addresses range at the row 533 of TDA8290.C, for the tuner address is at 0xe1./* probe for tuner chip */ tuners_found = 0; tuner_addrs = 0; for (i=0x60; i<= 0xe1; i++) { msg.addr = i; ret = i2c_transfer(c->adapter, &msg, 1); Now, loading: eeprom firmware-class saa7134 i2c_scan=1 the result is saa7130/34: v4l2 driver version 0.2.14 loaded ACPI: PCI Interrupt 0000:01:00.0[A] -> GSI 21 (level, low) -> IRQ 21saa7133[0]: found at 0000:01:00.0, rev: 208, irq: 21, latency: 64, mmio: 0xfeafe800 saa7133[0]: subsystem: 11bd:002f, board: Pinnacle PCTV 310i (saa7131E) [card=89,autodetected]saa7133[0]: board init: gpio is 600c000 input: Pinnacle PCTV as /class/input/input4 ir-kbd-i2c: Pinnacle PCTV detected at i2c-0/0-0047/ir0 [saa7133[0]]saa7133[0]: i2c eeprom 00: bd 11 2f 00 54 20 1c 00 43 43 a9 1c 55 d2 b2 92 saa7133[0]: i2c eeprom 10: ff e0 60 06 ff 20 ff ff 00 30 8d 2d 14 35 ff ff saa7133[0]: i2c eeprom 20: 01 2c 01 02 02 01 04 30 98 ff 00 a5 ff 21 00 c2 saa7133[0]: i2c eeprom 30: 96 10 03 32 15 20 ff ff 0c 22 17 88 03 48 e9 3a saa7133[0]: i2c eeprom 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff saa7133[0]: i2c eeprom 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff saa7133[0]: i2c eeprom 60: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff saa7133[0]: i2c eeprom 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ffsaa7133[0]: i2c scan: found device @ 0x10 [???] saa7133[0]: i2c scan: found device @ 0x8e [???] saa7133[0]: i2c scan: found device @ 0x96 [???] saa7133[0]: i2c scan: found device @ 0xa0 [eeprom] tuner 0-004b: chip found @ 0x96 (saa7133[0]) tuner 0-004b: setting tuner address to e1What is this? This can not be correct. Did you change something in the probing code in tda8290.c?
tuner 0-004b: type set to tda8290+75a x saa7133[0]: registered device video0 [v4l2] saa7133[0]: registered device vbi0 saa7133[0]: registered device radio0 As easy to see, I2C is able to find several devices. Device address description 0x10 0x08 i2c-controller ??? 0x8e 0x47 pctv-irda/ir-kbd-i2c 0x96 0x4b saa7131E ??? 0xe1 tda8290+75a 0xa0 0x50 eeprom0x10 is the tda10046 channel decoder0x8e most probably is the ir chip. On the 300i, it causes a lot of troublesince sometimes it replies without being addressed... 0x96 is the tda8290 IF core in the saa7131 0xa0 is the saa7131 config eeprom The tda8275a is not visible here is it is located after a bridge, most probably the one in the tda8290. Pierluigi (is that right?) did i already tell you this? This is why you first need to talk to the tda8290 beforeyou access the tuner yust like it is for the tiger board. It most probablyhas the address 0xc2. Again: 0xe1 can not be right, it not even is a valid write address.At the moment I'm trying many solutions for DVB-T, but the results ar quite disappointing.All I obtain is always: tda1004x: pll set failed Here are the changes I made to SAA7134-DVB.Cstatic int pctv310i_pll_set(struct dvb_frontend *fe, struct dvb_frontend_parameters *params){ int ret; ret = philips_tda827xa_pll_set(0xe1, fe, params); return ret; } static int pctv310i_pll_init(struct dvb_frontend *fe) { return 0; } static void pctv310i_pll_sleep(struct dvb_frontend *fe) { philips_tda827xa_pll_sleep( 0xe1, fe); } static int pctv310i_request_firmware(struct dvb_frontend *fe,const struct firmware **fw, char *name){ struct saa7134_dev *dev = fe->dvb->priv; return request_firmware(fw, name, &dev->pci->dev); } static struct tda1004x_config pctv310i_config = { .demod_address = 0x08, .invert = 1, .invert_oclk = 0, .xtal_freq = TDA10046_XTAL_16M, .agc_config = TDA10046_AGC_TDA827X, .if_freq = TDA10046_FREQ_045, .pll_init = pctv310i_pll_init, .pll_set = pctv310i_pll_set, .pll_sleep = pctv310i_pll_sleep, .request_firmware = pctv310i_request_firmware, }; Put dvb-fe-tda10046.fw in the firmware directory and at the module loading: modprobe saa7134-dvb DVB: registering new adapter (saa7133[0]). DVB: registering frontend 0 (Philips TDA10046H DVB-T)... tda1004x: setting up plls for 48MHz sampling clock tda1004x: found firmware revision 20 -- okI also found this post in a forum that made me think I'n not aiming the correct way..."The tuner is - as far as i know - a TDA8275a. This is supported. Butthe application of the tuner is different, it has an external preamplifier. This requires a different strategy for the AGC - which is not implementedyet. But it might work at least a bit without it. The other issues:I can't belive that there is no firmware eeprom on the card but its addressmight be controlled in a different way. You need to use the pll_init and pll_sleep functions to switch the board between analog and dvb mode. This mainly is switching the AGC source between analog IF and the channel decoder. I have no idea how this is done on the pinnacle board. Some boards do this by just setting the outputs to tristate (the chip drivers do this when they go to sleep mode). But most use an analog multiplexer (4052), controlled by some GPIO pin. It is the hard part of the job to find which one."Maybe this helps a bit. Hartmut
