LabVIEW 2020 Community Edition on Raspberry 3 B v1.2


Recommended Posts

Hey Community,

 

at first I want to introduce myself.

My name is Heiko from Germany. I also ask for understanding for my English as I'm not a native speaker.

I was very happy to hear that the new LabVIEW Community Version was released, because you can now implement very simple projects with the Raspberry.

Immediately I tried to connect my Raspberry 3 B to the LINX Target Configuration to LabVIEW.
Unfortunately there encountered some problems during the installation, which and I hope you can help me with.

After I had successfully connected to my Raspberry, I received the following message during installation.

"The target LINUX partition is only 5GB of the available 7GB. It is recomendet to expant the partition."

After I expanded the partion with the Configuraton tool, I received a message that ererything was sucesfull.

But I have to say that I expanded the LINUX Partition manually bervore (via fdisk) to the mximum capacaty of my 32 GB card.

After I continued with the installation I receided the following message. (copy from the log.txt)

+++++END of the Log.txt+++++

 

In the log text the device type Raspberry Pi 2 B is mentioned, but I have an Raspberry Pi 3 B.

Even if the installation failed, I was able to start the sample project (LED).

After I restarted the system, I was unable to establish a connection to the Raspberry and received the message "Connection to dhcpcd lost".

What can cause this problem and how can I solve it?

So I took a look at the code that pulls the device info and ya, my assumption was correct. Actually, not sure why they are even reporting on the model type. It should just return the generic type. Like Raspberry Pi. No need to report the exact model, since you will always be wrong and really, it doesn't matter.

Thank you for the reply and your support. I followed your instruction and I don't received any message concerning the partition.

So the problem with the partition is solved.

But before the installation was finished the following error message was shown.

+++beginning of the message+++

+++end of the message+++

Never the less the example project was running once.

After rebooted the pi I can't get any connection to it.

The strange thing is that I haven't changes any IP address or network settings.

I also tried to post this problem to the MakerHub forum, but I haven't received any reply.

Ok i found the problem. Since the Raspi did not always connect independently in the explorer project, I replaced the host name "raspberry" in the target configuration under the network settings with the ip address. This has probably destroyed the DHCPCD host.
