RE: Enabling USB Gadget Ethernet on the Ultra96-V2

Hi,

I follow the instruction and running the script obtaining in the windows side:

Looking to the drivers

I tried to update drivers, but it is not the solution.

In the other hand, when I use the Pynq image (2.6 or 2.7), everything goes smooth.

I tested in different Windows machines and in a native ubuntu 20.04 with same results.

Any suggestion?

Best Regards, G

Thank you.

The u96v2_sbv_vitis_2020_2.tar.gz image I got also contains this script and I was able to use it.

Currently I run the script after logging in via UART, but is there an easy way to run this automatically at boot time?

On Ubuntu, there seems to be a way to use /etc/rc.local, but

However, this does not seem to be available in this environment.

Thank you Tom,

This write-up was exactly what I was looking for to get X11 forwarding working between the Ultra96-V2 and my Windows 10 PC [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-26f4edd1-70ab-441b-9ed8-7b67d425bf14/5504.contentimage_5F00_1.png:16:16]

I needed to configure the TCP/IPv4 Properties for the detected RNDIS ethernet driver for a static IP address of 192.168.3.2 to match the address of the Ultra96-V2, which is 192.168.3.1.
Works smooth, thanks again !
Mario.

I'm attempting to run on this to connect a Ultra96-V2 to a Windows 10 64-bit host but the RNDIS driver keeps failing to configure for the Ultra96-V2. The same system works fine with a BealgeBone and RNDIS and I can run the same Ultra96-V2 on a newer Laptop which has USB 3.0 ports just fine. The PC with the issue has USB 2.0 only so I am not sure if that is an issue. The same issue is seen with the latest PYNQ build as well on the same Ultra96-V2

This is what I see when I run the './usb_gadget_ethernet.sh':

It just hangs here.

Also, Device Manager on the Windows host show this for the RNDIS driver:

Updating the driver does not correct the issue.

Looking at this from a Ubuntu VM on the Windows 10 host, it does seem to show an available device and I can assign it to the VM

However, after setting an IP on the VM, the device eventually is disabled and I can not connect to it.

Are there any known conflict on Windows 10 with the RNDIS driver for the Ultra96-V2?

Can I use USB gadget with other Avnet boards, like UltraZed and MiniZed?
