How to import assembly files and compile them in STM32CudeIDE ?
When I create a .s source file in a project, I cannot even save the file, and STM32CudeIDE only reports an error:

Save failed

AST is empty

Can you create any other files?

This worked for me:

1. select a Source folder in your project
2. right-click and choose New > File
3. name it <whatever>.s
4. edit as required
5. save
6. build

Thank you for your reply.
Yes, I can. If I edit and input the C code into the new file, it will work properly. However, when entering ASM code, an error will be reported.
I tried to modify startup_stm32h750vbtx.s in the Startup folder for testing purposes, and then saved it, but the same error occurred.
I speculate that STM32CudeIDE treats the. s assembly file as C code and attempts to establish a syntax tree to provide editing assistance This may be a bug in STM32CudeIDE.

Mine (v1.13.0) recognises .s files fine, and will create, edit, and build them correctly.

There must be an issue in your installation.

My IDE version is 1.18.0, I will try reinstalling it to see if it can solve the problem. Thanks a lot.

"AST is null" is from Eclipse

I just reinstalled 1.18.1, and the problem still exists.

Have you installed some Eclipse add-on from eclipse store?

Edit the assembly file in any other editor.

After installing multiple different versions of the IDE, I solved the problem by creating a new workspace. Thank you very much!
