{{Warningbox|ChipWisperer v5.1.3 before commit 3557 and arm-none-eabi-gcc before q2-2018 can produce non-working binaries for the STM32F3. The only fix is to update either ChipWhisperer or gcc}}

== Hardware AES ==
The STM32F21x, and STM32F41x/43x have hardware crypto modules (AES, DES, TDES) along with hardware hash (SHA1, MD5). Hardware crypto for the STM32F4 has been integrated into the Hal build system on the develop branch. To use the hardware crypto, call HW_AES128_Init() at the beginning of your program. You can update the key with HW_AES128_LoadKey(), encrypt plaintext with HW_AES128_Enc(), and decrypt data with HW_AES128_Dec(). == CAN Connection == A 6-pin header is present for devices which have CAN hardware support (not all devices have this). A CANoodler can be plugged in to provide the physical transceiver. This header is not normally mounted, unless the board is part of an 'automotive bundle'. The header is left unmounted as it can impede sweeping a probe over the surface of the chip.
== Programming Connection ==
=== ChipWhisperer Programmer via Bootloader ===
See further down this wiki page for details.
=== JTAG Programmer ===
The 20-pin JTAG port (J6 on CW308 Board) can be used with the [https://www.digikey.com/product-detail/en/stmicroelectronics/ST-LINK-V2/497-10484-ND/2214535 ST-LINK/V2] which is a low-cost JTAG programmer.
== Example Projects ==
SimpleSerial builds for each of the STM32Fx Devices. Each device is a separate HAL, these . These HAL's modules have been copied from ST's HAL (not the CUBE) and greatly reduced in size by deleting unused files (such as headers for unused devices), and combining several C-source files into a single low-level C-file. Many example projects are available via Jupyter Notebooks: https://chipwhisperer.readthedocs.io/en/latest/tutorials.html. Note that all of these examples were created for the CWLITEARM (equivalent STM32F3) target. You will need to make changes based on which target you have to run the tutorials. For some tutorials, changing the PLATFORM variable in the first block to the one you're using is enough to get the tutorial working:<syntaxhighlight lang=python>SCOPETYPE = "OPENADC"PLATFORM = "CW308_STM32F4" #For STM32F4 target, was originally "CWLITEARM"</syntaxhighlight>
=== Building ST Example on Command Line ===
The regular firmware build process works with the STM32 devices. For example, to build `simpleserial-aes`, navigate to the folder `chipwhisperer\hardware\victims\firmware\simpleserial-aes` and run the following command on the command line:
<code>
make PLATFORM=CW308_STM32F0 CRYPTO_TARGET=TINYAES128C
</code>

=== Rev -03 Schematic ===
The current revision of the target is -03. The following shows this schematic:
[[File:CW308T_STM32F_03.png|1100px]]
=== Rev -02 Schematic ===
The original board sold was the -02 revision. The revision is part of the part number, for example these boards will be marked STM32F-02. The -02 revision also does not have the CAN connector:
