Mini Maestro on the Nvidia Jetson Nano

I have been using the Mini Maestro 18 on a Windows 11 machine and a Raspberry Pi 4 and I can confirm that the Pololu Maestro Control Center application works on them.

However, I am attempting to use the Mini Maestro 18 on a Jetson Nano and while the devices are visible, I get this strange error that states: “Error loading settings from the device. Failure has occurred while loading a type.” Whenever I try to select one of them.

I have two Mini Maestros connected to the Jetson Nano via USB mini and can confirm that the connections are tight and the cable works since it worked on my PC and RPi 4.

I am in serious need of help as It appears that the Jetson Nano does not have any drivers for the Mini Maestro unlike my PC or RPi 4.

Hi,

Unfortunately, the engineer most knowledgeable about the Maestro software is out this week. Hopefully he can help you troubleshoot and possibly get it working once he’s back, but my understanding is that the Maestro Control Center tends to have issues on ARM-based Linux machines (so I’m surprised it worked for you on the Raspberry Pi 4). Can you accomplish what you want to do using the Maestro command-line utility usccmd instead?

I just tried that and I got this message:

Hello. I am sorry you are having trouble using the Maestro software on your Jetson Nano.

Could you please run the following command to get a list of all mono-related packages installed on your system, and post the full output from it?

dpkg --get-selections | grep mono

Also, what is the output of these commands?

cat /etc/lsb-release
cat /etc/os-release

Also, here are links to download two older versions of the Maestro software for Linux. Do either of these work for you? If not, what error messages do you get when you try to use them?

maestro-linux-220509.tar.gz
maestro-linux-201002.tar.gz

So here is what I get from dpkg --get-selections | grep mono:

And from cat /etc/lsb-release and cat /etc/os-release:

I can confirm that the two older versions of the Maestro software do work, but I do get an error code 1 on both of them. Hopefully it is nothing important.

Thanks for the details. I was able to find a solution and release a fixed version of the software, so if you download the latest Maestro Linux software from the user’s guide, it should work.

I have downloaded and tried it and I can confirm that this new release works. Thanks!
