= Setting up the Hardware =
This tutorial uses the [[CW1173 ChipWhisperer-Lite]] hardware. This hardware does not require any special setup - it should be ready to go out-of-the-box.
This tutorial uses the [[CW1002_ChipWhisperer_Capture_Rev2]] hardware along with the [[CW301_Multi-Target]] board. Note that you '''don't need hardware''' to complete the tutorial. Instead , you can download [https://www.assembla.com/spaces/chipwhisperer/wiki/Example_Captures example traces from the ChipWhisperer Site], just . Just look for the traces titled ''AVR: AES256 Bootloader (ChipWhisperer Tutorial #A5)''.
This example uses the Atmel AVR in 28-pin DIP programmed with a demo bootloader. You can see instructions for programming in the [[Installing ChipWhisperer]] section, this tutorial assumes you have the programmer aspect working.
The Multi-Target board should be plugged into the ChipWhisperer Capture Rev2 via the 20-pin target cable. The ''VOUT'' SMA connector is wired to the ''LNA'' input on the ChipWhisperer-Capture Rev2 front panel. The general hardware setup is as follows:
<blockquote>[[File:hw-1.jpg|image]]
# 20-Pin Header connects Multi-Target to Capture Hardware
# VOUT Connects to SMA Cable
# SMA Cable connects to 'LNA' on CHA input
# USB-Mini connects to side (NB: Confirm jumper settings in next section first)
</blockquote>
Jumpers on the Multi-Target Victim board are as follows:
<blockquote>[[File:hw-2.jpg|600px|image]]
# NO jumpers mounted in XMEGA Portion or SmartCard Portion (JP10-JP15, JP19, JP7-JP8, JP17)
# 3.3V IO Level (JP20 set to INT.)
# The 7.37 MHz oscillator is selected as the CLKOSC source (JP18)
# The CLKOSC is connected to the AVR CLock Network, along with connected to the FPGAIN pin (JP4)
# The TXD & RXD jumpers are set (JP5, JP6)
# Power measurement taken from VCC shunt (JP1)
# The TRIG jumper is set (JP28) (NOTE: Early revisions of the multi-target board do not have the TRIG jumper and you can ingore this).
For more information on these jumper settings see [[CW301_Multi-Target]] .

== Building/Programming the Bootloader ==
TODO. Notes to self:* Make sure bootloader code is in repo* Makefile* Describe code (aes, bootloader, supersecret)
