Emulator for STM32H745

Hello,

We are using a hardware with STM32H745 controller with FreeRTOS.

Can you please suggest a good PC Emulator which can be used to emulate above controller with FreeRTOS.

Also we use UART, SPI, LED, CAN peripherals on the actual hardware. Can these peripherals be emulated?

Some options I looked at are QEMU and Renode but not sure about STM32745H7 support or FreeRTOS support.

Thanks & Regards,

Anuj

The hardware structure of the STM32, especially the Cortex-M7 based STM32F7 and STM32H7 is so complex that an emulator or simulator would be much too expensive. In this respect, the answer is: no, there is (currently) no emulator or simulator .

However, there are universal evaluation boards called NUCLEO with which you could test all of them live.

    Hi 

    Thanks for the super quick reply:)

    Do you mean to say there no ready made emulator /simulator or STM32H745? 

    Few options I checked QEMU, Renode, Proteus. Your thoughts on the same?

     

    Also If I want to simulate only the software with RTOS and not the hardware then are there any good options?

    Thanks & Regards,

    Anuj

    Yes.

    With on-chip debug and low-cost boards like Nucleo, there's really no call for it nowadays.

    See the Windows simulator link, above.

    As @Peter BENSCH said, emulators haven't been viable for decades now.

    Instead, microcontrollers have debug built-in - accessible via JTAG or SWD.

    So you can use actual target hardware, while getting all the internal access that Emulators used to give.

    To examine FreeRTOS features which are independent of the target hardware, there's a Windows simulator:
