6. All f iles present on your local PC i n “qemu-arm-img/workdir” will n ow b e present in a
directory called “workdir” on your emulator, similar to the below image:
7. To compile your program, run the following command: “gcc -o
filename>.s -g”
a. “-o ” determines the name of the resulting executable
. “.s” specifies which ARM source file to attempt to assemble
c. “-g” links the program for debugging
