Software description:

The JTAG of RV debugger + can be used without driver in Windows and Linux. Theoretically, macOS is the same. The official system has integrated FT2232 driver. RV debugger + simulates a standard FT2232HL. In theory, it is compatible with FT2232 simulation environment and can be used. It is recommended to use the OpenOCD tool chain. No driver is required to use the virtual serial port. If unknown hardware appears under Windows, please use a third-party tool to install the driver (such as the driver wizard).

The maximum communication rate of RV debugger + JTAG is 2.5Mhz, and the baud rate supported by the virtual serial port is up to 2MJTAG. Gowin FPGA is not supported temporarily.
(Later firmware update can be downloaded from:

About secondary development:

The main chip BL702 of the RV debugger+ integrates the BLE function, so the debugger reserves the corresponding impedance matching circuit and 20x12mm ceramic patch antenna pads when leaving the factory. If you need secondary development, please refer to the official website link of Boliu Smart for the software SDK. For the hardware part, please go to the Sipeed download site to obtain the corresponding HDK.

Pressing the BOOT button without releasing it and then connecting to the computer will make the RV debugger+ enter the download mode. With the official Bouffalo engineer BLDevCube, it can download the firmware to the debugger. See the tool usage guide:
