Hello Now the product is not CD, the information is on the box website, thank you. Product introduction ST-LINK/V2 is an online simulation can be downloaded as well as STM32 and STM8 development tools. Basic properties ST is ST-LINK/V2 sense method for the evaluation of the semiconductor, the development of STM8 series and STM32 series MCU and the design of online simulation and download as one of the development tool. STM8 series through the SWIM interface and ST-LINK/V2 connection; STM32 series through the JTAG / SWD interface and ST-LINK/V2 connection. ST-LINK/V2 through high speed PC and USB2.0 end connection. Supported software Utility v2.0 ST-LINK (and above) Version 4.2.1 STVD (and above) Version 3.2.3 STVP (and above) EWARM Revision v6.20 IAR (and above) EWSTM8 Revision v1.30 IAR (and above) RVMDK Revision v4.21 KEIL (and above) ATOLLIC TASKING Supported devices Support all STM8 Series MCU with SWIM interface Support all STM32 Series MCU with JTAG / SWD interface Function and performance Programming function: can be burned to write ROM EEPROM, FLASH, AFR, etc.. Simulation functions: to support full speed operation, single step debugging, breakpoint debugging and other debugging methods, can see the state of IO, variable data, etc.. Simulation performance: the use of USB2.0 interface for simulation debugging, single step debugging, breakpoint debugging, fast response Programming performance: the use of USB2.0 interface, SWIM / JTAG / SWD download, Download speed Connection interface to the target board ST-LINK/V2 specifies the SWIM standard interface and the JTAG / SWD standard interface. Firmware upgrade Firmware update. ST will launch more stm8 and STM32 models, the new device types added into stvd device support list when you in future development needs using the latest models, stvd upgrade, upgrade the firmware, and will be able to support the new model. Upgrade mode for automatic upgrade.
