Steps for Compilation and Run

Perform compilation using below command:

$ scons

Note: For clean compilation, you can use following command:

$ scons --clean

If the compilation is correct, the “rtthread.elf” file will be generated in the BSP directory, which is a target file required for QEMU to run.

qemu-vexpress-a9$ ls -lrt rtthread.elf
    -rwxrwxr-x 1 test test 1866252 Apr 12 16:40 rtthread.elf

Use the ./qemu.sh command to run the Project.

$ ./qemu.sh

The above command will start the virtual machine and BSP project.
The initialization information is displayed and version number information is printed during the start-up of RT-Thread system.
The QEMU virtual machine also starts running as shown below:

Directory /:
dev                 <DIR>

Now run below commands to print “hello RT-Thread”:

msh />echo "hello RT-Thread" hello.txt

msh />ls
