Thank you for sharing your project but I didn't reproduce the issue and the application passed SCB_EnableDCache() step and I see this screen (stepped over SCB_EnableDCache():(

Your project is running well in debug and in standalone.

Try maybe to use the latest tools CubeMx/CubeIDE and clean/rebuild your project.

Hello @Oussama_Baklouti and welcome to the community.

Where did you call SCB_EnableDCache()? before MPU config? if yes, need to move the call after the MPU config.

Could you please share your code? you attached a rar containing only .cprojet file!

Please attach your complete projet.

Does the frame was sent ?

SofLit · ‎2024-08-19

Which frame?

Your problem was: "when debugging i found that the code blocked in an endless loop in SCB_EnableDCache() function"

So the issue was that your application was not even passing the first two lines in the main.

Did you already solve that issue or not? or it's a new one? if yes please close that thread and create a new one with a new description.

The problem isn't solved ,the code blocked in an endless loop in SCB_EnableDCache() function .And while debugging this is what happen

As suggested, did you try to use the latest version of the tools: CubeMx/CubeIDE?

Do you have another board to run the same test?

As I didn't reproduce the issue, the issue is not in the code itself.

In any case, I'm attaching the project I used for the test.
