I have installed DVBSDR according the guideline in BATC Jetson Nano Wiki, but got a list of warnings. The TX script seems to run.
Before I proceed with connecting the Jetson Nano to Portsdown and LimeSDR I would like to know if those warnings are serious and I should work on them first.
Although initially a mumber of OMs copied my instructions and they worked perfectly, I have heard a few weeks later that people have had problems, probably due to shared libraries being updated. However, unlike the Portsdown, I don't monitor for problems with this build as there are not enough hours in the day. These instructions are not part of the "supported" Portsdown build.
It's difficult to help you without knowing what the error messages were.
If the warnings included
Code: Select all
limesdr_dvb.cpp:643:2: sorry, unimplemented: non-trivial designated initializers not supported
It wasn't until today I had a chance to check the components.
I'm using vMix on a laptop with HDMI out to an LKV373; this sends UDP through a small dedicated network to my Jetson Nano, Portsdown controls the Nano inputs and outputs.
After a process of elimination it looked like my Jetson was heading back to Nvidea. Then I wondered about that connector which links the two boards; J2 a SODIMM connector, I'd had problems with these in a laptop where they are used to mount memory cards. So as not to invalidate the warranty I decided just to dismount the sub board and then ensure it was pushed fully home.
Much to my delight it did the trick and I'm back in business.
that's exactly the problem I had with the same set up except I use OBS rather than Vmix.
I still suffer from the same problem occasionally but find that by running the jetson_nano script with Videosource_IP and turning off the resolution calc (ie telling the script 1920x1080 resolution) the system starts to work at which point the RPI can take over control and all is usually fine.
I will try your solution and see if it makes my system more stable. I have my Jetson in a little metal box and cooling fan on top.
Thanks for the tip !
When I posted this up I thought it unlikely anyone else would have a similar problem. It's still working fine and still a mystery, possibly just a tarnished contact. Good luck it's worth a try.
Yes mine's in a box because I nearly killed it off tripping over a wire; I use this one; it's bomb proof.

Is anybody use the DVBSDR on the Jetson to stream info to Adalm Pluto ?
I tried here but no way... Just setting the Freq OUT, choosing IP as output and write the ip of the Pluto will be enough ?
Portsdown does not work with the ADALM-PLUTO.
There are programs that do, DATV Express and there is firmware, e.g. Plutoweb that you can load to the Pluto that can send and receive DATV, but not anything to do with BATC. See here:

Can we add this to the Wiki as this must be at least the 5th time someone has asked.
