Hello,
I am testing the am335x processors using a Beaglebone Black. I am trying to boot using RNDIS and tftp to do an initial dataload. It would make life easier if this could be managed from a VirtualBox linux machine.
On the beaglebone, I have zeroed out the eMMC so there is nothing on the board. When the USB mini cable is plugged in, I get a USB RNDIS device on my Linux Host. I can see DHCP requests over the USB network device.
To move this to Virtualbox, I have used vagrant to configure a virtual machine like this:
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/xenial64"
config.vm.box_check_update = false
config.ssh.forward_agent = true
config.vm.synced_folder "../../tisdk/build/arago-tmp-external-linaro-toolchain/deploy", "/yocto_deploy"
config.vm.provider "virtualbox" do |vb|
vb.memory = '256'
vb.customize ['modifyvm', :id, '--usb', 'on', '--usbehci', 'on']
vb.customize ["modifyvm", :id, "--ioapic", "on"]
vb.customize ['usbfilter', 'add', '0', '--target', :id, '--name', 'Texas Instruments AM335x USB', '--vendorid', '0x0451', '--productid', '0x6141']
vb.customize ["modifyvm", :id, "--hwvirtex", "on"]
end
config.vm.provision "shell", inline: <<-SHELL
apt-get update
apt-get dist-upgrade -y
apt-get install -y tftpd-hpa tftp isc-dhcp-server
SHELL
end
But when the Beaglebone Black is plugged in, the VirtualBox log file says:
00:09:35.220858 ERROR [COM]: aRC=NS_ERROR_FAILURE (0x80004005) aIID={872da645-4a9b-1727-bee2-5585105b9eed} aComponent={ConsoleWrap} aText={Failed to create a proxy device for the USB device. (Error: VERR_READ_ERROR)}, preserve=false aResultDetail=0
Other USB devices can be inserted into the virtual machine without any issues. It's just the AM335x processor in USB boot mode that has an issue.

Has anyone managed to get USB boot working with an AM335x processor under VirtualBox?
Thanks,

Hello,
I am testing the am335x processors using a Beaglebone Black. I am trying to boot using RNDIS and tftp
Not being able to use a Virtual Machine is a real problem for me as I run Ubuntu and don't want to mess up my machine configuration with the RNDIS / DHCP configuration.
Although VirtualBox does not currently support RNDIS devices (at least I couldn't find a solution), I found a work around by bridging network devices into the virtual machine.
1. On the Linux Host, setup UDEV to run a script when the Sitara RNDIS device is inserted:
/etc/udev/rules.d/40-setup_rndis.rules:
ACTION=="add", SUBSYSTEM=="net", KERNEL=="usb*", RUN+="/usr/local/bin/setup_rndis.sh start '%E{INTERFACE}' %k %n"
ACTION=="remove", SUBSYSTEM=="net", KERNEL=="usb*", RUN+="/usr/local/bin/setup_rndis.sh stop"
2. On the Linux Host, edit /usr/local/bin/setup_rndis.sh
IF=${INTERFACE}
cat <<EOF > /etc/NetworkManager/conf.d/$IF.conf
[keyfile]
unmanaged-devices=mac:$(ifconfig $IF | head -n 1 | awk '{print $5}')
EOF
service network-manager force-reload
ifconfig ${IF} 0.0.0.0 up
ifconfig br0 up || brctl addbr br0
brctl addif br0 ${IF}
3. In VirtualBox, make your network interface "Bridged" to br0
Yes, you are bridging your VBox interface to a bridge. :) The USB interface frequently goes up and down, so adding it to a bridge stabilizes the connection between the Host and VM.
Now, whenever the RNDIS device is inserted, the USB Interface will be added to the br0 bridge. The virtual machine is bridged to that interface, so it will get all network traffic from the Sitara. The VirtualMachine can run the DHCP server and TFTP and serve u-boot, zImage, etc to the Sitara.
