Gen 3 Verification and Test OS (VTOS) is for PCB test and flash programming support for 32-bit ARM Cortex MCUs from ST Microelectronics.
Supports processors in the STM32 L1 family that use ARM Cortex-M3. VTOS program NOR USB programs NOR flash device while using a USB connection for file transfers. Reportedly produces flash programming results 2.5x faster than ST Link Utility and 12x faster than ST DFU. VTOS Scan Core tests GPIO, I2C, SPI, and UART devices. VTOS Scan USB tests USB device interface. VTOS Scan ADC tests ADC interfaces. VTOS Developer tool is for test creation and running tests interactively. VTOS Runner tool automates running of tests and programming steps.
