Easy Installer access Ubuntu 22.04 RNDIS USB problem

Hello everyone.

I’m trying to install the Easy installer in the Apalis iMXD6( lxora carrier board ) and open the remote desktop using the VNC, as described here(Downloads & Installers | Toradex Developer Center). I’m using ubuntu 22.04 LTS and I installed the Vinagre VNC client. I followed all the steps provided, but when I tried to access the board using Vinagre(192.168.11.1) I received the message saying that the “connection to host 192.168.11.1 was closed”.

Here are the output messagem from the dmesg | grep usb command:

Could someone please help me?

Best Regards,

Hi @andrehpd-eld ,

Do you have access to the serial interface? If yes, can you please check if the module got the IP 192.168.11.1 before trying to connect using VNC? You can check this by running the command ifconfig.

Best regards,
Daniel Morais

Hi @daniel_m.tx .

Sorry for the long delay in the answer. We found that the network interface wasn’t being properly configured in ubuntu. After activating it, I was able to connect throught VNC in ip 192.168.11.1.

Best Regards,
