| Target Device | Atmel SAM4L |
| Target Architecture | ARM Cortex M4 |
| Hardware Crypto | Yes |
| Supported Apps | Simple Serial Enc/Auth |
| Status | Released |
This board supports the Atmel SAM4L microcontroller. The default build has the Atmel ATSAM4LC2AA-AU, which has 128KB flash and 32KB SRAM.
Hardware AES
The SAM4L has a hardware AES module, with optional countermeasures that can be enabled.
Programming
An external programmer is needed for this target. The SAM4L has an internal bootloader you can use via an external serial port, which is not yet supported directly by the ChipWhisperer-Capture software.
JTAG Programmer
The 20-pin JTAG port (J6 on CW308 Board) can be used with the ATATMEL-ICE which is Atmel's JTAG programmer. You can use any other ARM programmer you might have as well (i.e., OpenOCD, Segger J-Link, etc).
Using Atmel SAM-BA
Atmel SAM4L has a built-in bootloader. Not this bootloader is NOT ROM-Resident - if you reprogram the device the bootloader is lost, since it is stored in flash memory. It is recommended to use an external JTAG programmer for this target, as since the bootloader is not ROM-resident it can easily be overwritten by accident (i.e., if connecting a JTAG programmer).
SimpleSerial Program
The SimpleSerial-AES program can be built for this target. This can use either hardware crypto or a software AES. This project is currently built via the Atmel Studio IDE, and the project file is located at hardware/victims/firmware/simpleserial-aes/ide_projects/asf/sam4l-simpleserial-aes with the ChipWhisperer release.
This uses the SAM4L HAL that is part of the build process. An automatically generated makefile can be modified to built in Linux, but currently has not been integrated into the rest of the system.
