All-in-one tool makes STM32 microcontrollers more user friendly and secure

By Nick Flaherty

Following on from the acquisition of Atollic last week, STMicroelectronics has launched a new tool for its STM32 microcontrollers to simplify the development process while making it more secure.
The STM32CubeProgrammer (STM32CUBEPROG) upgrade runs on Windows, Linux, or MacOS operating systems to program the on-chip Flash/RAM or external memories using various file formats. It adds whole-memory or sector erase and programming microcontroller option bytes and users can also generate encrypted files for secure programming (Secure Firmware Install/Update) to authenticate production and protect intellectual property.

Access is via the device’s SWD (Single-Wire Debug) or JTAG debugging ports, or the bootloader ports (such as UART and USB), so the tool brings together the ST Visual Programmer, DFUse Device Firmware Update tool, Flash Loader, and ST-Link utilities. ST plans to extend the STM32CubeProgrammer’s capabilities by adding programming access via microcontroller I2C and CAN ports, presumably as a result of the Atollic deal
The tool can be customised and used in standalone mode or integrated and controlled from a custom application. Programming can be done manually or automated using scripts.
