i2c wr failed #5

Closed rickwookie closed 6 years ago

rickwookie commented 7 years ago

Had a bunch of issues getting this to compile and run on a clean RPi 3 raspbian install (Linux raspberrypi 4.4.26-v7+ #915 SMP Thu Oct 20 17:08:44 BST 2016 armv7l GNU/Linux), but got there in the end.

Anyway, trying to use this it seams that there's a problem communicating with the dabstick hardware:

lsusb gives me: Bus 001 Device 004: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T

and running ./dab_cmdline I get:

... Found Rafael Micro R820T tuner samplerate set to 2048000 Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=09 len=1 r82xx_set_freq: failed=-9 going to tell the world no ensemble, quittingwe told the world ofdmProcessor is shutting down

Any ideas where to start with this?

r82xx_write: i2c wr failed=-9 reg=09 len=1

Are you sure that the stick is supported by the osmocom driver? best jan

ok so I just installed rtl-sdr, the ran rtl_test -t and get: Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6 Sampling at 2048000 S/s. No E4000 tuner found, aborting.

Which I think is normal right?

Then I did rtl_fm -M wbfm -f 92.6M | aplay -r 32k -f S16_LE -t raw -c 1 and I get: Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001

...and from the headphone jack on the RPi3 I can hear the radio station.

JvanKatwijk commented 7 years ago

I am not able to reconstruct the behaviour you are describing, that makes it more complex to "debug". The error line is Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=10 len=1 The expected output here would be as stated in your previous mail.

Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6

So I can precisely tell you in which line of the code it goes wrong, but since it happens in a function contained in the rtlsdr library. so I have to dig somewhat deeper

Thanks.

Further info, my versions of librtlsdr and libusb: pi@raspberrypi:~ $ dpkg -s librtlsdr0 librtlsdr-dev libusb-1.0-0 libusb-1.0-0-dev | grep Version Version: 0.5.3-3 Version: 0.5.3-3 Version: 2:1.0.19-1 Version: 2:1.0.19-1

hope that's useful.

Is there difference in behaviour if you run the program as root? I never us the rtlsdr package that is part of the distribution, I download recent sources and build a version jan

Hmmm there's a suggestion here: http://www.hamradioscience.com/raspberry-pi-as-remote-server-for-rtl2832u-sdr/#comment-27496 that it could be power related, but I've tried a few power supplies and rtl_test never fails on me with that error, only dab_cmdline. Also I can listen to FM radio using rtl_fm with no issues. It's not likely that a power issue would occur ONLY when running dab_cmdline is it?

I'll try to build rtl-sdr from source. Does that create librtlsdr-dev too?

rickwookie commented 7 years ago

I've removed the repo packages librtlsdr0 librtlsdr-dev rtl-sdr and built rtl-sdr from source as you've suggested. The only difference now is an extra line in the output of both rtl_test and dab_cmdline: [R82XX] PLL not locked!

Done a bit more digging and it seems that the RPi 3 could well need a 5V 2.5A PSU. Best I've tried is 5.1V 2.1A. I'm awaiting delivery of a couple of 5V 3A adapters and I'll let you know if this is the issue.

Edit: I've just tried hooking up an independent 5V 2.5A PSU to the USB bus, but still this error persists. I have to conclude that the power thing may be a red herring

I've finally got DAB!

IT was the shockingly bad DAB signal that was the reason I wasn't getting it before. Managed now using the local ensemble and holding the antenna VERY HIGH.

This output message still persists though, although it seems perhaps it can be ignored if it has no effect on the functioning of the program.

Looks interesting, I wonder then where the error messages are coming from. One would suspect that the frequency is not set prior to the samplerate setting (the thing reports that the PLL is not locked).

I'll look into the rtl-sdr code best jan

Hi, I've the same issue with my Astrometa DVB-T2 stick (ID 15f4:0131 HanfTek). The stick was not found by ./dab_cmdline when using librtlsdr from wget http://sm5bsz.com/linuxdsp/hware/rtlsdr/rtl-sdr-linrad4.tbz

JvanKatwijk commented 7 years ago

Seems to me that something is double, very well possible. Apparently the list of supported devices for the osmocom software is larger than the more specialized - and older - library from linrad.

The error you are getting is seen before, since I cannot reconstruct it here it is a little difficult to react. From what I ve seen before, the stick functions, regardless of the error message -9, and if it functions it sends data. Apparently no ensemble was received, since that is what the report is telling : no ensemble found.

The difficulty with command line versions is that you do not see anything, no signal no constellation so there is no way to tell whether the signal is decent or not.

It looks like, dab_cmdline is performing a scan using the given channel (e.g. "-C 5C"). The gain value seems to be important. Audio is played using the default ALSA device.

BUT... unfortunatelly I have to execute dab_cmdline very often (>50 times) to get it working like above. All the other tries are not successful.

I'm not the expert and I'm just thinking loud... Could it be, that the detection of a valid starting point of the stream could be improved? Is 'Autogain' supported, that I do not need to care about it?

JvanKatwijk commented 7 years ago

The gain value is extremely important. Note however that - from an implementation point of view - the qt-dab and dab-cmdline are equivalent. I do not know the receiving conditions in your area, but it is my experience that using the settings as seen optimal for the qt-dab are also working good for the dab-cmdline version.

I'll think on the autogain, might be a good suggestion

Hi Jan, to give you a feedback: I tried the latest sources and after rebuilding I tested the command: ./dab_cmdline -C 5C -P "Deutschlandfunk" -Q It does not play. Error: no ensemble, ... Where as when ommiting option -Q it is working (probably, because of a default gain value?).

andimik commented 7 years ago

Then I would say: Use another stick. Nowadays people are throwing away or at least selling them as there are no DVB-T signals in lots of regions any more (Munich included). Try to get one with E4000 tuner, which were quite rare. NOXON-Stick v2 might be the right one but nobody would sell it.

I have 6 different sticks at home.

JvanKatwijk commented 7 years ago

I do not know much about the sticks, I seldom use one, but is the autogain value dependent on the reglar gain value that is set? If so, use both gain and autogain since in the implementation first the gain is set then the autogain'

@andimik I tried a NooElec NESDR SMArt (having a R820T2 tuner IC, as I can not help with E4000) with command: ./dab_cmdline -C 11D -P "BR-KLASSIK" -Q and this stick is working (!!!) even the same error is displayed: Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=09 len=1 r82xx_set_freq: failed=-9 r82xx_write: i2c wr failed=-9 reg=07 len=1

@JvanKatwijk I just saw sth strange with the command above and using my Astromety stick again: Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=09 len=1 r82xx_set_freq: failed=-9 r82xx_write: i2c wr failed=-9 reg=07 len=1 program (1): D314 BR-KLASSIK in the list program (2): D313 BAYERN 3 in the list program (3): D911 Bayern 1 Schw in the list program (4): D412 Bayern 2 Sued in the list going to tell the world no ensemble, quittingwe told the world ofdmProcessor is shutting down

Is strange to me, as BR-KLASSIK is in the list, but not found, then?

I also tried: ./dab_cmdline -C 11D -P "BR-KLASSIK" -Q # not playing ./dab_cmdline -C 11D -P "BR-KLASSIK" -G 80 # playing ./dab_cmdline -C 11D -P "BR-KLASSIK" -G 80 -Q # not playing

If I understood you right, then the third command should play radio?

The confusion may arise that you see program names passing by. However, the decision whether or not an ensemble is found ismade by having recognized - or not - the name of the ensemble. If that happens, then it is assumed that the synchronization has reached its final offset and is further switched off. That is just a choice.

Since the software (at least the qt-dab software) should run on a rpi 2, and since the synchronization as such is pretty heave, synchronization takes two threads to execute, and they obviously have to talk to each other. In my experience, switching sync off on the ensemble name is more reliable than switching off on a program name

Wrt the last question: I do not know wat autogain is doing related to the regular gain setting, all I am saying is that the current implementation first does the regular gain setting, then the switches the autogain on (my stick in mechanically extremely weak, and sdrplay and airspy outperform a stick to such an extent that I only use the stick for specific tests)

@andimik https://github.com/andimik I tried a NooElec NESDR SMArt (having a R820T2 tuner IC, as I can not help with E4000) with command: ./dab_cmdline -C 11D -P "BR-KLASSIK" -Q and this stick is working (!!!) even the same error is displayed: Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=09 len=1 r82xx_set_freq: failed=-9 r82xx_write: i2c wr failed=-9 reg=07 len=1

@JvanKatwijk https://github.com/JvanKatwijk I just saw sth strange with the command above and using my Astromety stick again: Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=09 len=1 r82xx_set_freq: failed=-9 r82xx_write: i2c wr failed=-9 reg=07 len=1 program (1): D314 BR-KLASSIK in the list program (2): D313 BAYERN 3 in the list program (3): D911 Bayern 1 Schw in the list program (4): D412 Bayern 2 Sued in the list going to tell the world no ensemble, quittingwe told the world ofdmProcessor is shutting down

Is strange to me, as BR-KLASSIK is in the list, but not found, then?

I also tried: ./dab_cmdline -C 11D -P "BR-KLASSIK" -Q # not playing ./dab_cmdline -C 11D -P "BR-KLASSIK" -G 80 # playing ./dab_cmdline -C 11D -P "BR-KLASSIK" -G 80 -Q # not playing

It is not the best idea to start testing a stick with this command line tool. Please try qt-dab or welle.io first, then you will see, which gain parameter is the best for your area, your stick and your hardware.

Every stick is different and supports lots of gain settings. In your case 29.

Have you tried dabtools as well?

MkMunich commented 7 years ago

Dear andimik, thanks for your hint - I know that both sticks are working in qt-dab and in dab-cmdline, when using the correct gain values + other settings. Perhaps you did not know, that when using in a driving car an 'Autogain' function is not just nice to have?

JvanKatwijk commented 7 years ago

The autogain function works pretty well with an sdrplay device, so the first thing that we have to find out is what the combination autogain on and gain setting does - and can be influenced - for simple sticks. The sensitivity of the sticks is obviously limited and they deliver only 8 bits, one sign bit and some noise and you have a or 4 bit left which does not deliver enoughto decode

I'll dig up my stick and run a few tests with qt-dab to see what the behaviour is with gainsetting/autogain

It turns out that after setting autogain "on", you better set a gain value, so I made a change in that direction on the dabstick handling software.

Hi Jan, I've a short question: I saw, that the configuration could be set from outside. This is a very good idea! But I do not know, how to call it, so I commented out the if statement in CMakeLists.txt like:

Mk if(DEFINED DABSTICK)

set(DABSTICK true)

Mk endif ()

Could you give an example, how to call the build of e.g. DABSTICK ?

MkMunich commented 7 years ago

Hi Jan, your update is looking ok. the command: ./dab_cmdline -C 11D -P "BR-KLASSIK" -G 80 -Q is now working. This is what I thought, that the order was wrong before. GREAT!

The error: Supported gain values (29): r82xx_write: i2c wr failed=-9 reg=09 len=1 r82xx_set_freq: failed=-9 r82xx_write: i2c wr failed=-9 reg=07 len=1 is still present, but not causing damages. I did not dig into it, and I'm only guessing, that it might be a wrong access to the gain value table? This would be a typical error from myself ;-)

JvanKatwijk commented 7 years ago

the cmake command understands -DDABSTICK=ON, so assuming you created a build directory cmake .. -DDABSTICK=ON

Wow Jan, you're so quick :-) The latest sources solved the i2c wr issue.

There are 2 comments to build dab-cmdline: 1) Is there a need for python 3.5.*? The installed python version in Jessie is 2.7.x. I got 3.4 with: sudo apt-get update sudo apt-get install python3-dev Then I had a need to adjust all paths to point to '/usr/include/python3.4m' in ~/dab-cmdline/dab-library/CMakeLists.txt

2) There is a small dependency issue in the build order, because of the new default, that PYTHON is set in ~/dab-cmdline/dab-library/CMakeLists.txt. The quick&dirty solution for me was to comment line:

set(PYTHON true)

And built using the following commands (in my case!): cmake .. -DDABSTICK=ON make -j4 sudo make install Then I deleted the '#' and did the same commands again.

Have a nice weekend.
