DL1JM Libresdr-DVBS2 firmware

[itaniepitas]

My opinion on the highly advertised firmware of the DL1JM.
I have a PlutoLibre that works wonderfully. I have set up the USB port as well as the Ethernet port.
Out of curiosity, I thought to try the so-called Libresdr-DVBS2 (4Gigs) firmware.
I write it to a freshly formatted SD card with Balena and place it in the slot.
I connect the USB cable to the device, trying, based on the instructions, at least to have it recognized as a Pluto by SDR-Console via the USB connection.
I did not connect Ethernet because I did not want, for the moment, to change any settings related to the IP ports, which I had already set.
The only thing I managed to observe is that each time you connect it to the computer, it gets a different COM port.
Nevertheless, it was impossible to get it to work.
Also, even with the Ethernet port connected, it was not recognized by the application.
So, it went straight to the recycling bin.
It is not acceptable that someone should have to mess with their existing settings for questionable firmware that also has no documentation and circulates by word of mouth like the Holy Grail secret.
Back on road with knows works well firmware.

the big fw (with modulator and webpage) ONLY WORKS VIA ETHERNET!!!
once set up correct it works superb and in my view it IS ACCEPTABLE to mess with settings on a freshly formatted sd card ... how should manfred know what ip number you wanna use??
if you do not know HOW to install and use a fw ... you should not moan about it ... ASK SOMEBODY FOR HELP would be the right way

ASKING YOU TO STOP THE OFFTOPIC MUMBLINGS. go to manfred's github, thank you!

[DG9BFC]

its not offtopic .. the topic is/was "DL1JM Libresdr_DVBS2 firmware" so please stop comment on my posts
all others: FEEL FREE TO ASK FOR HELP IF YOU WANT TO TRY ONE OF THE TWO FW FROM MANFRED

[gretel]

so please stop comment on my posts all others

sei so gut und fasse dir bitte an die eigene nase.

[DG9BFC]

sidenote .. on the same mega folder you will find a fw "libresdrx0426" ... that has NO MODULATOR AND NO WEBPAGE ... only ptt out and 10mhz sync ... and works via usb and ethernet ... so if youi want to use usb ... and do not need the datv modulator ... then try the smaller one

[itaniepitas]

Yes blah blah blah. This firmware it's rubbish if not followed by clear documentation. Ask who ? You or them? No thank you. Here the firmware have a superior support. You keep what you like and leave us to comment what i found. Have a nice stay with them.

[itaniepitas]

I return to the section because I need to add some things so that the whole picture exists of what is happening with the mentioned firmware.
I am not a supporter of anyone, and I do not take a side for any reason of interest for or against. I will refer to the latest conclusions I have noticed in the past few days.
Unlike the first firmware, the so-called DATV, I have nothing more to add.
I wrote it at the beginning. However, there is also the second one that has been posted, and here things are completely different.
This is a simple boot firmware from DL1JM (libresdrx0426) which really impressed me.
First of all, I should say how I connect my SDRs.
They connect directly to the computer via Ethernet without a router or switch in between. Also, sometimes i use USB connection for test.
Unlike the first one firmware, this did not require any changes at all in these network settings that I have made on my computer.
So, I wrote this firmware to an SD card and started the SDR.
It works fantastic both in narrow and wide band. The truth is truth. Especially in clock locking. I use external 10MHz external timing.
Its stability is something I am seeing for the first time. A rock steady.
Also, nothing unnecessary utils it runs in the background, and overall, it is top-notch firmware. Because the correct things also need to be written.
I will use it; Yes.

at first you have moaned about the "datv" fw not running on usb and now you tell us that you use ethernet direct?!? that makes me wonder a bit .. but ok .. if you like it .. use it (via usb or ethernet)
the bigger one with datv modulator has the same stability (locked via 10mhz)
BOTH FW can be used via dhcp .. or with modding a file can be set to fixed ip but only the x0426 runs also on usb
the big one can be switched to "SDRMODE" (means similar to the small fw with no modulator and all unneeded things switched off) .. or to "Performance mode" (datv modulator and webpage running) ...
so what fw to use depends on if you use your sdr ONLY in IQ MODE (then the smaller fw will be ok for you) or if you also want the modulator inside the sdr and stream direct from obs to the device (similar to what dozens of users do with a pluto and evariste fw)
....
yes you can ask ME ..or MANFRED ... or a few others (who already use that fw) ...
that FW from Manfred was at first made only as a private project ... that is why there is no github folder, no source files and not the very best documentation ... and after a few others were asking to get a copy he made that mega folder and uploaded the fw there
there just exist no real source files cause the fw is "stitched together" from a few different fw (libre and pluto) plus some handwritten (or edited) files from Manfred to get all that working ... me is/was one of the beta testers for him .. that is why i know a few things about it
...
so you like the x0426?? fine :-) ... (you still can ask if you need further help)
sidenote: i can get up to 26mhz bw over ethernet with that "small" fw!!! ... and yes with locking to external 10mhz it is ROCK STEADY and does not do "jumps" up down on the last digit of the tuning DAC ....
in normal the 12 bit resolution is too coarse ... but with a clever programming trick it can be made finer (and as we can see it works fine)

Hi Sigi...Can you put the link to the source archive (mega folder I guess). About DATV in tezuka, for users with 7020 fpga, dvbs2 modulator in fpga is nearly ready to deploy.

[DG9BFC]

hello Evariste .... you should maybe use some parts of manfreds fw for your fw (the 10mhz is working superb and does NOT JUMP on the last digit up down!!)
and he is using YOUR FPGA modulator already (copy from pluto fw)
hmm?!?!?
greetz sigi dg9bfc

[F5OEO]

and he is using YOUR FPGA modulator already (copy from pluto fw)
No, this version of modulator is running on the arm of Zynq. Efficient, but could be cpu intensive at high Symbolrate.

[DG9BFC]

here:
https://mega.nz/folder/x6hFxCgK#GCcuiII_XcBPNLPDq88Osg
small one without datv (but usable via ethernet and usb) is libresdrx0426
just unzip and save on an sd card ... boot via usb and edit the config file (similar to pluto fw) ...
big one with datv modulator is datvlibre126
that needs to be "burned" on sd card (its an IMAGE FILE) so needs windiskimager or similar to be used
also in that firmware you find a settings file where you can change from dhcp to a fixed ip (yes that needs some editing)
questions about what files need to be changed?? ASK!! (either me or direct to dl1jm manfred)
Evariste it is NOT a folder with sources to compile ... it is "only" a working image cause it is "stitched together" from different sources and then manually edited a few things until all worked
and manfred is still working on it to make things better or adding new things like "testpattern" tx direct from webpage
(means you should check that link every few weeks or so)
as noted ... before moaning about it ... ask for help (install may be a bit tricky depending on your own setup)

Yes, that's a result..not the source.
I see a note from Manfred :
_"The Datv-project for Fishball is closed now, because of incompatible hardware
compared to the private Libre-project versions 1.2x and above.

It takes too much time to check all different hardware-models on the market
and it should stay here a private-project for the LibreSDR only."_
That's why Tezuka exists ! Focus on applications, contribute and you will be compatible with all boards !

I understand that it was a personal project, not intended to be public, but opensource community need to be collaborative : every contribution empower the whole project.

[DG9BFC]

the only reason why i "poke your nose" onto manfreds fw is that you maybe can grab a few things for your own fw and for other users (with a libre) to use manfreds fw if they want a datv capable fw with good 10mhz ref working (or use the naked one if you only want raw iq mode with sdrtv and sdrconsole)... at least one can try out if that fits their needs and i only offer help cause i know so many details about that fw

[itaniepitas]

Sigi
I would ask you to finally stop presenting yourself as an expert on everything and in every forum.
We are not some passersby from the hobby.
When I have a system that I have set up to work the way it works, and every firmware change does not require me to change my home network settings, it is welcome for test or use. However, when I have to do it for something for which there is no functional documentation, I simply don’t do it and throw it in the recycle bin. It’s that simple.

[DG9BFC]

i am an expert on several things or at least "know something" .. and if i can help .. i do (thats living ham spirit .. nothing else!!)
doing the hobby now for over 40 years so yes i have "some" knowledge accumulated over the time
and yes i also write in other forums ...
about the fw from manfred .. it was me who brought him onto the libre sdr and we both together made that fw (ok main work from him .. i was "just" betatester" and helped him on some problems with brainstorming on a few phone calls, email exchange etc etc ) ... that is why i know some internals of his fw .. what file contains what .. where to set fixed ip instead dhcp or other things like preset and offset setting (needed for 10mhz to properly work) ...
if you find the bare "non datv" fw useful .. just use it and have fun with it
.....
why did i write about his fw in tezuka forum?? cause tezuka does NOT work good with the 10mhz reference (yet!!) and i hoped that evariste "jumps on the train" (copy the 10mhz regulation) in his fw ... manfred is using evaristes modulator so its a give and take
its a hobby and why can we not each "learn from the other" ... hmm??

[itaniepitas]

I would suggest to you completely friendly and without any intention of further confrontation to get down from the chair you have climbed on to appear taller than the others. Just My Two Cents.

[DG9BFC]

i just like to help if i can and i spend a lot of time in our hobby ... i am betatester on several soft and hardware things and love to try new things out ... or in other words i am very active in several things ... i do NOT want to appear taller .. why should I ??
at least that is not my goal here or on any other forum where i write
confrontation?? I never want that .. so please no flame-throwing ... it just hobby and you are free to not read my postings if you do not want to
best 73

Note that latest 0.3.12 version has now datv modulator integrated (on FPGA) and works with EasyDATV as plutodvb2 compatible. The missing part compared to Manfred : input clock - it is planned.

[DG9BFC]

hopefully you can get it as smooth as the other firmware does (no jumps on last digit)

[itaniepitas]

Give him instructions on how to do it. And if he fails, take back the programming degree you gave him.

[gretel]

that is a very expert thing to say, i'm very impressed by your skillset and the way you present yourself.
