| − | The ChipWhisperer-Lite Bare Board consists of two main parts: a multi-purpose power analysis capture instrument, and a target board. The target board is a standard microcontroller which you can implement algorithms onto. For example if you wish to evaluate an AES library, you can program that library into the target board and perform the power analysis.

| + | |
| − | | + | |
| − | <p>The last option is the most reliable, in that it should always work on all platforms. If it doesn't start look for possible missing modules or other useful errors.</p>
| + | |
| − | <blockquote><p>'''hint'''</p>
| + | |
| − | <p>The first time you run ChipWhisperer-Capture or -Analyzer, the default setup of the screen is somewhat insane. You can drag windows around or close them to make it look more like the demos here. See the Video quickstart guide as well for details of that.</p></blockquote></blockquote></li>
| + | |
| − | <li><p>From the "Scripts" directory, run the <code>ChipWhisperer-Lite: AES SimpleSerial on XMEGA</code> script:</p>
| + | |
| − | <p>[[File:cwlite_simpleserial.png|image]]</p>
| + | |
| − | <p>This should connect to the ChipWhisperer-Lite, program the FPGA, and run a few captures. Your screen should look something like this now:</p>
| + | |
| − | <p>[[File:cwdemo_normal.png|image]]</p></li>
| + | |
| − | <li><p>If the previous step fails, you may need to set the path for the "firmware". This is done by going to the "Tools" menu and selecting the "Config CW Firmware" option. Note on MAC OS X a special command is required instead sometimes, see [[MacOSX_Installation]].</p>
| + | |
| − | <p>From there, hit the "FIND" button beside the "FPGA .zip (Release)" option. Point it to the file located at <code>chipwhisperer/hardware/capture/chipwhisperer-lite/cwlite_firmware.zip</code> on your filesystem.</p></li>

| − | # See [[Tutorial_B5_Breaking_AES_(Straightforward)]]for details. Note the hardware setup is slightly different -- but you can skip to step 5.5.3, and should be able to pick up from there. Be sure to use the <code>ChipWhisperer-Lite: AES SimpleSerial on XMEGA</code> script instead of the one referenced in step 5.5.3.

| − | == Important Bugs/Caveats ==
| + | |
| − | | + | |
| − | The following includes various things that might trip you up:
| + | |
| − | | + | |
| − | # If you save the project ''before'' running the capture, you can specify any directory. Traces will be copied to the appropriate location during capture.
| + | |
| − | # If you save the project ''after'' running the capture, you must save the project to the same directory that "default-data-dir" exists in. This is normally the folder from where you invoked the Python GUI.
| + | |
| − | # There are a few warnings/exceptions that come up (i.e. divide-by-zero). Generally just keep going and see if things are still working. A number of those are on the ''TODO'' list to fix but I didn't get around to it yet.
| + | |
| − | # The "Total Ops" window which checks for proper AES operation requires PyCrypto to be installed.
| + | |
| − | # By default the XMEGA device was programmed with a partial AES implementation only. This is done to avoid any crypto export issues. This does not affect your side-channel analysis, but be aware the returned value might not appear to be correct (since only the first couple rounds of AES occurred).

| − | | + | |
| − | == Upgrading SAM3U Firmware ==
| + | |
| − | | + | |
| − | When talking about the ChipWhisperer-Lite's firmware, there is really two parts to this:
| + | |
| − | | + | |
| − | # The FPGA Bitstream file.
| + | |
| − | # The SAM3U USB interface chip firmware.
| + | |
| − | | + | |
| − | The FPGA bitstream alone is what is normally configured by the ChipWhisperer-Capture software. This bitstream is always the most up-to-date, since it's automatically reloaded by the computer every time you power cycle the ChipWhisperer-Capture. The SAM3U firmware however is not automatically updated, but it tends to change less frequently.
| + | |
| − | | + | |
| − | === Checking Firmware Version ===
| + | |
| − | | + | |
| − | The firmware version is printed at start-up. You will see a line that looks like this indicating the version of the SAM3U Firmware:
| + | |
| − | | + | |
| − | <pre>Found CW-Lite, Serial Number = 442031204630xxxxxxxxxxx
| + | |
| − | SAM3U Firmware version = 0.11 b0
| + | |
| − | Programmed FPGA</pre>
| + | |
| − | If your firmware version is outdated, a warning will be printed. You can also see the firmware version in the ''Config CW Firmware'' dialog:
| + | |
| − | | + | |
| − | <blockquote>[[File:sam3fwver.png|image]]
| + | |
| − | </blockquote>
| + | |
| − | Note the main version is 0.11 in this example. The "b0" indicates a "build" number. Typically this will be "build 0", but special versions will use a different build number to indicate a variant of a regular version.
| + | |
| − | | + | |
| − | === Upgrading Firmware ===
| + | |
| − | | + | |
| − | Before updating, you must put your ChipWhisperer-Lite into bootloader mode. Once put into this mode you will need to load a new firmware file. There is two ways of doing it: the ''automatic'' method, and the ''manual'' method. The automatic method is done through the GUI, and works if you have valid firmware image loaded. The ''manual'' method is always guaranteed to work.
| + | |
| − | | + | |
| − | The automatic method is:
| + | |
| − | | + | |
| − | Using ChipWhisperer-Capture GUI
| + | |
| − | | + | |
| − | # Connect to the ChipWhisperer-Lite.
| + | |
| − | # From the ''Tools'' menu select ''Config CW Firmware''
| + | |
| − | # Select the ''Open SAM3U Update Widget'' button.
| + | |
| − | # Press the ''Enable Bootloader Mode'' button.
| + | |
| − | # You will get an error, and the ChipWhisperer-Lite will disconnect. This is normal, and indicates the USB mode changed suddenly.
| + | |
| − | # The blue LED will stop flashing, and the device will reconnect in programmer mode (see below).
| + | |
| − | | + | |
| − | Once you are in bootloader mode, both the blue and red LED will be very dimmly lit:
| + | |
| − | | + | |
| − | [[File:lights_prog.jpg|400px]]
| + | |
| − | | + | |
| − | This indicates it is in bootloader mode. The device will now attach as a serial port. If you are using Windows this may take a few minutes to happen.
| + | |
| − | | + | |
| − | If using Linux, you can use ''dmesg'' to verify the serial port was connected OK.
| + | |
| − | | + | |
| − | If this doesn't work, see the page [[Manual SAM3U Firmware Update]] for details on how to manually enter bootloader mode. You can return to this page for the actual programming - you don't need to install/use the BOSSA utility if you follow those manual directions. You simply need to force the system into bootloader mode using those directions.
| + | |
| − | | + | |
| − | To actually program the file, we use the second part of the dialog box you already had open:
| + | |
| − | | + | |
| − | [[File:sam3uupdate.png|400px]]
| + | |
| − | | + | |
| − | Once we are in bootloader mode, you can follow these steps:
| + | |
| − | | + | |
| − | # Hit "Update List", and select the serial port the SAM3U attached as.
| + | |
| − | # To use the default firmware file, leave the "Built-in" radio-box selected. If you want a custom firmware you can select the "External" mode.
| + | |
| − | # Hit the "Run Program" button
| + | |
| − | # Once completed, unplug/replug your device and it should come to life.
| + | |
| − | # Close the update widgets, and reconnect to your ChipWhisperer-Lite.
| + | |
| − | | + | |
| − | === Manual Update ===
| + | |
| − | | + | |
| − | If the above instructions fail, there is no big problem. The SAM3U chip contains a hardware-resident bootloader. You may need to follow instructions on the [[Manual SAM3U Firmware Update]] page (including using BOSSA) if you are unable to use the automatic system that is part of ChipWhisperer-Capture.

| − | == Mounting Jumpers ==
| + | |
| − | | + | |
| − | Note the ChipWhisperer-Lite main board and target section contain a number of jumper options. By default these are not mounted, and solder jumper bridges on the PCB have been bridged to select the appropriate options when required. Some options are only solder jumpers, which to move the jumper requires a soldering iron to bridge or clear the appropriate connections.
| + | |
| − | | + | |
| − | The following lists jumpers on the ChipWhisperer-Lite / Target Section:
| + | |
| − | | + | |
| − | ; Capture Section Jumpers
| + | |
| − | * JP4 is the "RESET" net for the SAM3U processor.
| + | |
| − | * JP2 causes the SAM3U processor flash memory to be erased. When the chip is erased a rom-resident bootloader takes over. See section XXXXX for bootloader details.
| + | |
| − | * JP5 selects the IO voltage for the FPGA bank which connects to the 20-pin target. By default SJ6 selects this to be 3.3V. It is not recommended to change this, as it is easy to damage the FPGA by feeding an out-of-range voltage in.
| + | |
| − | * SJ1 selects if the power supply comes from the Micro-USB connector (default) or an external 5V supply at the +5VIN pin.
| + | |
| − | ; Target Section Jumpers:
| + | |
| − | * JP7 connects the "MEASURE" SMA to the XMEGA VCC Rail. Shorted by default with SJ4.
| + | |
| − | * JP6 connects the "GLITCH" SMA to the XMEGA VCC Rail. Shorted by default with SJ5.
| + | |
| − | * JP12 can be used to feed an external voltage into the XMEGA VCC Rail. By default SJ3 connects this to 3.3V.
| + | |
| − | * SJ2 selects if the 3.3V rail comes from the 20-pin IDC connector (i.e. ChipWhisperer-Lite board), or via an optional LDO and USB connector.
