    Embedded ST-LINK/V2-B The ST-LINK/V2-B on STM32F429I-DISC1 is embedded as a programming and debugging tool. Virtual COM port and USB mass storage features are supported by the ST-LINK/V2-B only for Mbed compatibility. The ST-LINK/V2-B makes the STM32F4429I-DISC1 boards Mbed Enabled. The embedded ST-LINK/V2-B supports only SWD for STM32 devices.
