See http://osdir.com/ml/linux-media/2009-06/msg01256.html for an explanation. For quick confirmation check if you have 12V - 20V DC going to your LNB. The relevant lines of code is in ~/v4l-dvb/linux/drivers/media/video/saa7134/saa7134-cards.c: case SAA7134_BOARD_VIDEOMATE_S350: dev-has_remote = SAA7134_REMOTE_GPIO; saa_andorl(SAA7134_GPIO_GPMODE0 2, 0x8000, 0x8000); saa_andorl(SAA7134_GPIO_GPSTATUS0 2, 0x8000, 0x8000); break; Hi thanks for the hint. I changed it to the following: case SAA7134_BOARD_VIDEOMATE_S350: dev-has_remote = SAA7134_REMOTE_GPIO; saa_andorl(SAA7134_GPIO_GPMODE0 2, 0xc000, 0xc000); saa_andorl(SAA7134_GPIO_GPSTATUS0 2, 0xc000, 0xc000); break; I now get the same SNR as on my skystar2 card, signal is still indicating 17% where as the skystar2 would show 68%. At least I'm getting a LOCK on channels :) Thanks! Looking at your log, at least the demodulator and tuner is responding correctly. You can see this by looking at the i2c traffic addressed to 0x1c (demodulator) and 0xc0 (tuner). Attached is a dmesg trace from my working SAA7130 based card. Regards JD Hi, Just to clarify, can you now watch channels? Hi Jan, yes I can watch channels on Vivid bouquet, some of which are FTA channels. Here is some channels I can get a lock and a picture on vdr: GodCh;GodCh:11674:vC56M2O0S0:S68.5E:26652:0:0:0:0:110:73:3:0 ASTV;ASTV:11674:vC56M2O0S0:S68.5E:26652:0:0:0:0:111:73:3:0 At the moment the signal strength measurement is a bit whacked, so don't worry too much about it. I also get the 75%/17% figures you mentioned when tuning to strong signals. The figure is simply reported wrongly: even weaker signals should tune fine. If you want you can have a look in ~/v4l-dvb/linux/drivers/media/dvb/frontends/mt312.c at mt312_read_signal_strength(). Also, if you have a multimeter handy, can you confirm that the 0xc000 GPIO fix enables LNB voltage? I'd like to issue a patch for this. I've already tested this on my older card with no ill effect. I will try and do this as soon as possible. Was there any worth while information in the ZL10313 documentation that could assist in setting the correct parameters for my Compro S300? I added the support for ZL10313 to mt312 driver. And at least for my card, the documentation of ZL10313 did help only a bit for setting GPIOs correctly. The most important step was tracing copper on the board, and having a look at how the windows driver sets the gpio lines. Have a look at my results: http://www.linuxtv.org/wiki/index.php/AVerMedia_AVerTV_DVB- S_Pro_(A700)#GPIO_table Most important pin to get correct is the one that resets demod, but you got it right it seems as you can tune channels :) Regards Matthias -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: Lenovo compact webcam 17ef:4802
The gspca module is provided as part of the kernel. The kernel version is 2.6.30-10 The libv4l version is 0.6.3-1 Is there a way that I can display the version of gspca?

Re: DVBWorld DVB-S2 2005 PCI-Express Card
I have a very similar problem with DVBWorld 2006 DVB-S2 card. The v4l-dvb ( freshly pulled ) compiles and loads, firmware is loaded, but when I actually try to use it ( dvbstream commands ) the following appears in /var/log/messages: Jan 4 18:30:24 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:24 november kernel: ds3000_readreg: reg=0xd1(error=-1) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_readreg: reg=0xd1(error=-1) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_writereg: writereg error(err == -1, reg == 0xf9, value == 0x04) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_readreg: reg=0xf8(error=-1) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_writereg: writereg error(err == -1, reg == 0x03, value == 0x12) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_tuner_readreg: reg=0x3d(error=-1) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_writereg: writereg error(err == -1, reg == 0x03, value == 0x12) Jan 4 18:30:25 november kernel: i2c_sendbytes: i2c error NAK or timeout occur Jan 4 18:30:25 november kernel: ds3000_tuner_readreg: reg=0x21(error=-1) ... and many more of this. Actually I have to say I already tried DVBWorld 2006, NetUP dual DVB-S2 and TwinHan VP-1041 ( like the Technisat card ) but no success at all. DVBWorld is giving me errors like above, NetUP's driver loads but doesn't want to tune to anything, Twinhan can tune to one transponder and scan the channels but for reasons far beyond me fails to tune to anything else. DVB-T ( Leadtek WinFast ) is working for me perfectly, but DVB-S is an exercise in frustration... -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[...] Hi, I'm not a developer, but I think that your device uses both of these chips. cx88 is the bridge chip, while the Xceive is the tuner chip. So, both of them needs to be supported in order for a device to work properly.

Re: CI USB
BTW, Hauppauge's WinTV-CI looked much more promissing. At least when I started reading whole thread about it here: http://www.mail-archive.com/linux-...@linuxtv.org/msg28113.html Unfortunatelly, last Steve's note about not getting anything (even any answer) has disappointed me fully. And because google is quiet about any progress on it I pressume no any docu nor driver was released later on. The whole project went badly wrong when the hardware vendor promised documentation then failed to deliver. My mistake for trusting them in the first place. I had considered running a driver reverse engineering tutorial project via kernellabs.com. Perhaps a 4 part series of writings, tools and instructions that describe how to reverse engineer USB drivers and culminates in a working skeleton driver for the WinTV CI that could be used. I doubt I could make this happen without a project sponsor so if you know any companies that would be willing to sponsor a project like this then I'd certainly be interested in helping.

Re: [RFC] dvb-apps ported for ISDB-T

On ISDB-T, there are several new parameters, so the parsing is more complex than all the other currently supported video standards. I've added the changes at: http://linuxtv.org/hg/~mchehab/dvb-apps-isdbt/ I've merged there Patrick's dvb-apps-isdbt tree. While there, I fixed a few bugs I noticed on the parser and converted it to work with the DVB API v5 headers that are bundled together with dvb-apps. This helps to avoid adding lots of extra #if DVB_ABI_VERSION tests. The ones there can now be removed. TODO: = The new ISDB-T parameters are parsed, but I haven't add yet a code to make them to be used; There are 3 optional parameters with ISDB-T, related to 1seg/3seg: the segment parameters. Currently, the parser will fail if those parameters are found. gnutv is still reporting ISDB-T as DVB-T. I've just fixed the issues on the TODO list. The DVB v5 code is now working fine for ISDB-T. Pending stuff (patches are welcome): - Implement v5 calls for other video standards; - Remove the duplicated DVBv5 code on /util/scan/scan.c (the code for calling DVBv5 is now at /lib/libdvbapi/v5api.c); - Test/use the functions to retrieve values via DVBv5 API. The function is already there, but I haven't tested. With the DVBv5 API implementation, zap is now working properly with ISDB-T. gnutv also works (although some outputs - like decoder - may need some changes, in order to work with mpeg4/AAC video/audio codecs). Very good job! Have you had a look here on this one http://www.mail-archive.com/v...@linuxtv.org/msg11125.html ? I had this on my list because I wanted to spent some time on DVB-S2 myself and it seemed to be a good step to merge it (back) into dvb-apps. Though I haven't yet looked at it in detail. I will check your changes soon, but after the holidays. So, now you should have some quiet time for yourself! ;-) Ok, I've added a version 2 of the isdbt-aware dvb-apps scan tools. Basically, this version: - checks if v5 API is available on a driver. If not, it falls back to v3 API; - v5api.c is now fully internal to libdvbfe. For library clients, it is fully transparent if it is using v5 or v3 calls; - scan now uses libdvbfe, instead of directly implementing the ioctls for v3 and v5. The code were simplified by the removal of lots of if's for v5 API; - scan now supports a few parameters present on DVB-S2, but there are still a few missing bits to fully support DVB-S2; - as my previous tree, dvb-apps has a copy of the dvb headers, since the headers are stable enough to work with older drivers and since the API version check is done by an ioctl call; - it addresses the pertinent issues that Manu pointed. It still remains the same, however. I had a quick look at it again: - dvb-apps/libs stopped using a separate copy of the kernel headers; ie kernel headers are expected to be at the default system locations, ie the kernel headers package. Because you added it in again, a test app szap2 had to be disabled for compilation. Changesets: 1332, 1334, 1348, 1357 - the library is falling on an expected operation for V5. This can fail if the API is V3 or something else. It should check the header version and if it is known to be greater than V3, then only it should issue the new V5 ioctl to test for version. This frees from an unnecessary test in the case of the V3 API. Changeset 1336 - Please do not apply partial features. Either apply it, or don't. Changeset 1341 - ATSC Cable is not DVB-C, even though it has some similiarities. Let's not get things mixed up. Changeset 1344 - Let the application send the number of properties, not the library to do memory allocation and deallocation. I mentioned about this one in my previous reply to your post. fill_sys_v5_params() -- count_props() Changeset: 1350, 1359, 1360 sizeof applies to a data structure, not the pointer, Changeset 1360 - maintain Backward compatibility with V3. Changeset 1351 Yet, this version is not properly tested, but, as I intend to be on vacations next week, I wanted to post what I have, even without all tests, to avoid the risk of someone to be working on DVB-S2 or other improvements to do a similar work. - Memory management needs string.h v5api.c:512: warning: implicit declaration of function ‘memset’ v5api.c:512: warning: incompatible implicit declaration of built-in function ‘memset v5api.c:567: warning: incompatible implicit declaration of built-in function ‘memset’ Maybe, it would simplify things, if I would pull in the changes till where it looks mostly right, the others
libv4l2: error mmapping buffer 0: Permission denied
Hello, I'm trying to get a labtec 2200 usb webcam working on my custom ARM platform. Since that webcam produces only images in pjpeg, I'm using libv4l2. I wrote a simple capture application where I want to read a single image in rgb24. When the application invokes v4l2_read I get the above error. The error comes from mmap which is invoked in libv4l2, but I've no idea whats wrong there. Can someone give me a hint how to fix this?

I'm yet to receive a response from you on this clear regression introduced
in the 2.6.31 kernel. You attention would be appreciated
Thanks
-Rob
Robert,
The changes in question (mostly authored by me) are based on
documentation on what offsets are to be used with the firmware for
various DVB bandwidths and demodulators. The change was tested by Terry
on a Leadtek DVR 3100 H Analog/DVB-T card (CX23418, ZL10353, XC3028) and
some other cards I can't remember, using a DVB-T pattern generator for 7
and 8 MHz in VHF and UHF, and live DVB-T broadcasts in UHF for 6 MHz.
(Devin,
Maybe you can double check on the offsets in tuner-xc2028.c with any
documentation you have available to you?)
I haven't been following this thread really at all as the board in the
subject line was unfamiliar to me, so sorry for any late response or
dumb questions by me.
May I ask:
1. what are the exact problem frequencies?
2. what is the data source from which you are getting the frequency
information?
3. what does tuner-xc2028 debug logging show as the firmware loaded when
tune to one of the the problem frequencies?
BTW, I note that in linux/drivers/media/dvb/dvb-usb/cxusb.c:
cxusb_dvico_xc3028_tuner_attach(), this declaration
static struct xc2028_ctrl ctl = {
.fname = XC2028_DEFAULT_FIRMWARE,
.max_len = 64,
.demod = XC3028_FE_ZARLINK456,
};
really should have .type = XC2028_AUTO or .type = XC2028_D2633, but
since XC2028_AUTO has a value of 0, it probably doesn't matter.

Andy

The erroneous pointer values we see are virtual addresses, whereas the USB controller would probably write a physical (or DMA) address if it was malfunctioning. Or it could be some bizarre timing problem with the memory bus, or something else equally obscure. You didn't mention before that this was a SoC rather than an ordinary PC.

Mauro,
I've split the revert2.diff that I sent you previously to fix the tuning
regression on my DViCO Dual Digital 4 (rev 1) into three separate patches
that will hopefully allow you to review more easily.
The first two patches revert their respective changesets and nothing else,
fixing the issue for me.
12167:966ce12c444d tuner-xc2028: Fix 7 MHz DVB-T
11918:e6a8672631a0 tuner-xc2028: Fix offset frequencies for DVB @ 6MHz
The third patch does what I believe is the obvious equivalent fix to
e6a8672631a0 but without the cleanup that breaks tuning on my card.
Please review and merge

Mauro,
I'm yet to receive a response from you on this clear regression introduced
in the 2.6.31 kernel. You attention would be appreciated
Thanks
-Rob
Robert,
The changes in question (mostly authored by me) are based on
documentation on what offsets are to be used with the firmware for
various DVB bandwidths and demodulators. The change was tested by Terry
on a Leadtek DVR 3100 H Analog/DVB-T card (CX23418, ZL10353, XC3028) and
some other cards I can't remember, using a DVB-T pattern generator for 7
and 8 MHz in VHF and UHF, and live DVB-T broadcasts in UHF for 6 MHz.
(Devin,
Maybe you can double check on the offsets in tuner-xc2028.c with any
documentation you have available to you?)
I haven't been following this thread really at all as the board in the
subject line was unfamiliar to me, so sorry for any late response or
dumb questions by me.
May I ask:
1. what are the exact problem frequencies?
2. what is the data source from which you are getting the frequency
information?
3. what does tuner-xc2028 debug logging show as the firmware loaded when
tune to one of the the problem frequencies?
Robert,
I just found that ACMA has a very nice compilation licensed DTV
transmitters in Australia and their frequencies. Have a look at the
Excel spreadsheet linked on this page:
http://acma.gov.au/WEB/STANDARD/pc=PC_9150
The DTV tab has a list of the Area, callsign, and DTV center freq.
The Glossary tab mentions that DTV broadcasters can have an offset of
+/- 125 kHz from the DTV center freq.
If you could verify that the frequencies you are using for the problem
stations match the list, that would help eliminate commanded tuning
frequency as source of the problem.
Regards,
Andy
BTW, I note that in linux/drivers/media/dvb/dvb-usb/cxusb.c:
cxusb_dvico_xc3028_tuner_attach(), this declaration
static struct xc2028_ctrl ctl = {
.fname = XC2028_DEFAULT_FIRMWARE,
.max_len = 64,
.demod = XC3028_FE_ZARLINK456,
};
really should have .type = XC2028_AUTO or .type = XC2028_D2633, but
since XC2028_AUTO has a value of 0, it probably doesn't matter.
Regards,
Andy

(Devin, Maybe you can double check on the offsets in tuner-xc2028.c with any documentation you have available to you?) At this point the extent to which I've looked in to the issue was validating that, for a given frequency, the change resulted in a crappy SNR with lots of BER/UNC errors, and after reverting the change the signal looked really good with zero BER/UNC. I haven't dug into *why* it is an issue, but I examined the traces and looked at the testing methodology and can confirm that there was definitely a regression and Robert narrowed it down to the patch in question. I was kind of hoping that one of the people that helped introduce the regression would take on some of responsibility to help with the debugging. ;-) I take responsiblity for the change. However, if fixing a known problem unmasks another problem, then is that a regression? I puzzled over the docs for a while until I had the Aha! moment and understood what they were saying. I'm really confident about the freq offset changes - especially since using the wrong center freq in channels.conf is an easy way to mask incorrect freq offsets in the driver module. I'm less confident about the xc3028 firmware segments as extracted and repackaged for linux. I was not involved in that development and I conveniently (for me) assume it is correct -- although that may be an assumption worth challenging. I also do not know the source of the commanded DTV freq's that are in use in the reported problem case. Using the wrong DTV center freq can cause the same problem symptoms as moving the offset used in the tuner-xc2028 module (two wrongs making a right). I just found a nice authoritative Australian source on DTV freq licensees (see my other foloow-up email), so hopefully Robert can double check that. Of course testing with a DVB-T generator instead of a broadcaster's signal would eliminate any doubt about the center freq in use. I think I have one of the boards that will demonstrate the issue (a Terratec board with xc3028/zl10353), and will try to find some time with the generator once I wrap up the xc4000 work for the PCTV 340e. OK, thanks. I have no hardware with which to test.

Sometimes it works, sometimes it doesn't, the end result is that I cannot leave the device plugged-in if I want to use it. I've also got a siano card, but in my case it's embedded in my Dell laptop, so yanking it out and plugging it back in isn't even an option.

I've tried the firmware you're referring too, but there's also a request for sms1xxx-nova-b-dvbt-01.fw in the dmesg and this is asked for first (in my case), with a siano supplied one sought if it can't find this first one. I'm not having problems with cold restarts, but suspend/hibernate sees the things go bad on resume. I've added some stuff to /etc/pm/sleep.d which unloads the modules and then reloads then on resume.
