-## Instructions for the Env tool
-
-When using Env tools, you need to enter the corresponding BSP directory in the Env terminal.

-### Configuration
-
-```
-menuconfig
-```
-
-Type the `menuconfig` command in the Env terminal to enter the configuration interface, and then configure the BSP:

-
-You can use the keyboard `↑` key and `↓` key to look up and down menu items, use the `Enter` key to enter the selected directory, use the `Space` key to select or cancel bool variables, and use the `Esc` key to exit the current directory.
-
-### Acquisition of software packages
-
-```
-pkgs --update
-```
-
-If a package is selected in menuconfig, download the package using the `pkgs --update` command. 
-
-The alternative and recommended way is by using `menuconfig -s` to select the `Auto update pkgs config` feature, so that when users exit the menuconfig, Env will automatically download and update software packages.

-### Compile

-Compile using the `scons` command, or `scons -j12` means 12 CPU cores compiling.

 After compiling, type `qemu.bat` to start the virtual machine and BSP project. `qemu.bat` is a Windows batch file. This file is located in the BSP folder, mainly including the execution instructions of QEMU. The first run of the project will create a blank `sd.bin` file under the BSP folder, which is a virtual SD card with a size of 64M. The Env command interface displays the initialization information and version number information printed during the start-up of RT-Thread system, and the QEMU virtual machine is also running.
