Step 0. Download new Kernel Package

Download the following onto your desktop computer:

and rename itgadgetkernel.tgz

Step 1. Copy New Kernel to SD Card

Copy the new kernel file over to theboot directory of the Jessie Lite card. After you're done burning the SD image, don't eject it just yet. Drag thekernel.tgz file over to the SD card. This way you can ferry the kernel into your Pi without needing network

Step 2. Log into your Pi Zero

Insert the SD into your Pi Zero, connect the console cable, power the Pi & log into via the USB console.

Step 3. Uncompress new kernel package

Uncompress and install thekernel .tgz file

 run the following commands:

• cd ~
• sudo mv /boot/gadgetkernel.tgz .
• tar -xvzf gadgetkernel.tgz

You'll see a long stream of file names ending withtmp/boot/kernel.img

Step 4. Backup and Install new Kernel

Run

• sudo mv /boot/kernel.img /boot/kernelbackup.img

to make a backup of the current kernel. Now run

• sudo mv tmp/boot/kernel.img /boot

You may see complaints about preserving ownership, you can ignore them

Step 5. Install Overlays & Modules

Run the commands to install the new overlays & modules

• sudo mv tmp/boot/overlays/* /boot/overlays
• sudo mv tmp/boot/*dtb /boot
• sudo cp -R tmp/boot/modules/lib/* /lib

Gadget Serial!

Now we'll tell the Pi we want to use theg_serial module

Run

• sudo nano /etc/modules

and addg_serial on a single line at the end, then save

Continue from this step for the rest of Serial Gadget setup and testing

Gadget Ethernet!

Now we'll tell the Pi we want to use theg_ether module

Run

• sudo nano /etc/modules

and addg_ether on a single line at the end, then save
