6. BLDevCube start guide

This document mainly introduces the use of Bouffalo Lab Dev Cube for code programming. For more details, please refer to BLDevCube user manual

6.1. Download Bouffalo Lab Dev Cube

  • Download the version suitable for your operating system from the developer community, download address:https://dev.bouffalolab.com/download

    • For users who do not have a registered account, click on the guest portal

  • After the download is complete, you can use it after decompression

6.2. Configure tool download method

  • Double-click BLDevCube.exe, in the Chip Type drop-down box, select the corresponding chip model, click Finish to enter the Dev Cube interface

  • Enter the interface, select MCU under View in the menu bar to enter the MCU program download interface

select mcu

  • Select the corresponding download method in the Interface column under Image, and choose according to your actual physical connection

  • Image file configure the absolute path of the downloaded image, click Browse to select the Bin file

  • When you click click here to show advanced options, the advanced mirroring configuration will be expanded, usually keep the default configuration; it should be noted that Flash Clock will affect the clock frequency of Flash and PSRAM at the same time , If you need to use PSRAM, you can increase the clock frequency to get better performance

6.2.1. Download with UART

  • COM Port is used for UART download, select the COM number connected to the chip, and click Refresh to refresh the COM number

  • When Uart Speed is used for UART download, configure the appropriate baud rate, the default is 2M

  • Please make sure the hardware configuration is correct before downloading:

    • Use Type-C USB or Mini USB to connect to the corresponding USB Type-C port or Mini port on the board.

    • Press the Boot key on the board, don’t release it

    • Press the RST key on the board, now you have entered Boot ROM model, you can release the two keys

    • At this time, you can see the corresponding serial port COM number from the Bouffalo Lab Dev Cube, if it does not appear, please click the Refresh button to refresh

  • After completing the above configuration correctly, click the Create&Program button to download

  • After the download is successful, you will see the status bar turn green and display Success

download success!

6.2.2. Download with Openocd

  • Download using openocd is basically the same as using serial port download option configuration, just switch Interface to Openocd

  • The hardware connection needs to be changed to a debugger connection that supports Openocd (this tutorial takes Sipeed RV Debugger as an example):

      1. Connect the RV debugger to the USB port of the computer, open the device manager, you will find that the debugger is recognized as two serial ports (note: not the serial port on the board)

      1. Download the zadig-2.4 replacement driver from sipeed. Download link: http://dl.sipeed.com/MAIX/tools/sipeed-rv-debugger/zadig-2.4.exe

      1. After downloading, double-click to open zadig-2.4.exe, and check List All Devices in Options.

      1. Find JTAG Debugger (Interface 0), then select the replacement driver as WinUSB and click Replace Driver to replace

      1. Open the device manager again and see that one of the serial ports has been replaced with a universal serial bus device, indicating that the installation is successful

      1. Connect the JTAG pins of the debugger with the JTAG pins of the board

  • After completing the above configuration correctly, click the Create&Program button to download

  • After the download is successful, you will see the status bar turn green and display Success
