Add STM32F4 support and USART device model

[PATCH v2 0/3] Add STM32F4 support and USART device model

Posted by fanyihao@rt-thread.org 3 months, 3 weeks ago

From: Yihao Fan <fanyihao@rt-thread.org>

This patch series introduces basic support for the STM32F407 SoC and
a new STM32F4spark machine in QEMU, along with a USART device model.

This series includes:
- A new SoC model (STM32F407) with initial integration.
- A board model called STM32F4spark to instantiate and test the SoC.
- A USART device implementation for STM32F4xx family.

For a new board model there are a couple of things we'd like
to see that aren't in this patchset:

(1) Documentation. This lives in docs/system/arm/. For
this board you want to add it to stm32.rst.

(2) A test case in tests/functional/ -- generally this is
something that downloads an image file from a public stable
URL, runs it in QEMU and checks for some output from the
guest on the UART indicating success. Lots of examples
in this directory to see how to do it.

Hi ,

Thanks for the review and helpful suggestions.
I will update the board documentation and provide a functional test case in the next version.

Best wishes,
Yihao Fan

Hi,
Just a gentle ping on this patch series:
  [PATCH v2 0/3] Add STM32F4 support and USART device model
https://patchew.org/QEMU/20250721201134.13270-1-fanyihao@rt-thread.org/



This patch adds support for the STM32F407 SoC, a new STM32F4spark board,
and a USART device model. Feedback would be greatly appreciated.



This patch will be applied in the /hw/arm directory.



Let me know if any changes are needed or if I should rebase it on a newer tree.
Best regards,
 Yihao Fan

Hi; thanks for the ping. This series is on my list to review,
but right now we are in the freeze period for the 10.1
release, so I've been concentrating on bug fix patches which are
going into the release. It may be a little while before I
can get to it. (Other people are of course welcome to review
it instead!)

thanks
