There is a lot of information on how the Internet giving more detailed explanation.Įcho 1 | sudo tee /proc/sys/net/ipv4/ip_forward > /dev/null It only works if your host PC doesn't have a firewall enable.
HOW TO USE CARELINK USB DEVICE HOW TO
The following shows how to enable, test, and disable. If your host PC is connected to the Internet (through WiFi or Ethernet), then you can allow the target device to share the host PC's Internet connection. Look at the values of RX packets: and TX packets.īridging host PC to allow device to reach the Internet On the host PC, verify the number of packet sent and received is not zero With the route showing the default gateway is using usb0 With an entry from the route output that looks likeĭestination Gateway Genmask Flags Metric Ref Use Iface G_ether gadget: high speed config #1: CDC Ethernet (ECM)įor this simple example, fixed IP addresses are assigned to the both the host PC USB network interface and the target device USB network interface. When you connect the cable, in the target device console, you should see: TX packets:1 errors:0 dropped:0 overruns:0 carrier:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 On the host you can verify the new usb0 interface exists by running:

HOW TO USE CARELINK USB DEVICE INSTALL
Selects: FEATURE_HAVE_RPC & FEATURE_SYSLOGīuild the SDK and install the new images to the target hardware.Īfter booting the target hardware to a shell prompt, run: Prompt: Support mounting NFS file systems
If you want the target to mount a host PC directory using NFS, then also enable NFS mount support in busybox: Prompt: Ethernet Gadget (with CDC Ethernet support)ĭefined at drivers/usb/gadget/Kconfig:628
HOW TO USE CARELINK USB DEVICE DRIVERS
Generally it is best to build USB gadget drivers as modules instead of building them into the kernel so you can unload one and load another. The USB Ethernet network gadget driver caused the device to appear to be a USB network dongle when connected to a host computer.
