What are the benefits of using QEMU over hardware?
There are several situations where it may be more practical to use QEMU instead of real hardware for testing and debugging:
- It allows you to quickly and easily test your code in various simulated environments without constantly deploying it to the target device
- If you don’t have the hardware that the software will be running on or if its availability is limited
- When you need to test software on multiple hardware platforms without having to set up multiple physical machines
- When you want to debug software in a controlled environment, such as reduced memory availability, to observe its behavior
- When you want to validate software that isn’t hardware specific and wish to reduce the time needed for testing, such as flashing, board wiring, and so on
However, it is essential to note that QEMU is a software emulator, which may not be a perfect substitute for real hardware at all times. Therefore...
