gl-silabs-dfu

本工程基于 silicon lab xmodem-uart-bootloader 和 silicon lab bgapi-uart-bootloader 进行固件升级。

Getting Start

$ git clone https://gitlab.com/gl.iot/gl-silicon-dfu.git

Run gl-silabs-dfu:

xmodem

gl-silabs-dfu xmodem [Upgrade file path] [Uart] [Reset IO] [DFU enable IO] [-v] [-c]

• -v: Printing the Upgrade Progress
• -c: Thread version checking
• -cb:BLE version checking

bgapi

gl-silabs-dfu bgapi [dfu mode] [Upgrade file path] [Uart] [Reset IO] [DFU enable IO] [-v]

dfu mode

• soft: software reboot triggers the dfu mode. In this mode, you don't need input a dfu-enable IO.

​ Warning: If your device is only software-enabled in DFU mode, any interruption during the upgrade will cause the firmware to mess up and work only by reburning the firmware. So we don't recommend using this mode.

• hard: hardware triggers the dfu mode. In this mode, you need input a dfu-enable IO.

Example

xmodem

# gl-silabs-dfu xmodem ./gl-efr32mg21f768-thread-rcp-v2021-10-19-1fbf6bb-71e4df982.gbl /dev/ttyUSB0 2 17 -v

upload ok. total size:80128
reset chip now...
dfu success!

bgapi soft mode

# gl-silabs-dfu bgapi soft ./test-high.gbl /dev/ttyS1 5 -v

GBL File Creation

环境部署

找到commander.exe的安装路径，并将该路径添加到系统Path环境变量,如下图：

生成未加密的GBL文件

打开工程文件，找到生成的 .s37 文件的路径，并在该路径下打开CMD命令行窗口，输入如下命令格式：

$ commander gbl create <gblfile> --app <filename> [--encrypt <keyfile>]

如下图所示，在当前目录下生成了未加密的GBL文件
