MiniZed doesn't recognize USB Ethernet

Question

Hi, I'm trying to add a usb ethernet port to connect to the MiniZed via wired Ethernet. It does not seem to be recognizing the Ethernet hardware. How can I get the hardware recognized and get drivers installed to get the hardware operational.

Thanks,

Brada

You'll need to add USB ACM & CDC drivers to your kernel build in Petalinux. I have this working for a Sabrent Ethernet dongle, which uses an ASIX chipset.. You could try this:

$ petalinux-config -c kernel

Kernel Config GUI:

Device Drivers

-> USB Support

<*> USB Modem (CDC ACM) support

Device Drivers

-> USB Support

-> USB Gadget Support

<m> CDC Composite Device (Ethernet and ACM)

Device Drivers

-> Network device support

-> USB Network Adapters

<*> Multipurpose USB Networking Framework

... add your chipset if you see it

You may also need to add the following to your /etc/network/interfaces file:

# Wired or wireless interfaces
auto eth0
iface eth0 inet dhcp

If you're not connecting to a DHCP router/switch, then you'll need to set the IP address manually in your interface file. Something like this:

iface eth0 inet static
        address 192.168.7.2
        netmask 255.255.255.0
        network 192.168.7.0
        gateway 192.168.7.1
