Is it possible to debug STM32 code without any hardware (no board, no ST-Link, no QEMU)?

Hello everyone,

I’m working with STM32CubeIDE (v1.19) and STM32 projects, but currently I don’t have any STM32 board or debug probe available.

What I want to achieve is not real hardware simulation, but something like:

• Step-by-step execution

• Breakpoints

• Variable watching

• Logical flow debugging

Constraints:

• :cross_mark: No STM32 board

• :cross_mark: No ST-Link / J-Link

• :cross_mark: No QEMU / Renode / Proteus

• :white_heavy_check_mark: Only PC-based development

So why not QEMU? It is pure software and free. ARM (Keil) provides a software simulator that works with their IDE & debugger.

So long as your code doesn't rely on any STM32 hardware interaction, you could build and run it in a PC native environment.

You can "stub" parts that would rely on STM32 hardware.

This is also a great way to test your embedded code!

(I am currently doing this to test/debug some STM32 accelerometer handling)

As @Pavel A. said, Why do you preclude QEMU? It is not a hardware simulator.

Anyhow, something like a Nucleo board is cheap - why not just get one?

If you use HAL for all your hardware interactions, you could just "stub" the HAL functions...
