MDK-ARM

1. Open the MDK-ARM toolchain.

2. Open the multiproject workspace file Project.uvmpw.

3. Select the xxxxx_s project as active project (set as active project).

4. Build xxxxx_s project.

5. Select the xxxxx_ns project as active project (set as active project).

6. Build xxxxx_ns project.

7. Load the nonsecure binary (F8).

(this downloads the \MDK-ARM\xxxxx_ns\Exe\xxxxx_ns.axf to flash memory).

8. Select the Project_s project as active project (set as active project).

9. Load the secure binary (F8).

(this downloads the \MDK-ARM\xxxxx_s\Exe\xxxxx_s.axf to flash memory).

10. Run the example.

STM32CubeIDE

1. Open the STM32CubeIDE toolchain.

2. Open multiprojects workspace file .project.

3. Rebuild xxxxx_Secure project.

4. Rebuild xxxxx_NonSecure project.

5. Launch debug as STM32 Cortex-M C/C++ application for the secure project.

6. Select the startup panel in the edit configuration window, and load the image and symbols of the

nonsecure project.

7. Load the nonsecure project before loading the secure project.

8. Click "OK".

9. Run the example on debug perspective.

5.1.2

Running a first TrustZone-disabled example

Before loading and running a TrustZone-disabled example, it is mandatory to read the example readme file for

any specific configuration or if nothing is mentioned, ensure that the board device has the security disabled

(TZEN=0 (user option byte)). See FAQ for doing the optional regression to TZEN=0.

1. Browse to \Projects\NUCLEO-U575ZI-Q\Examples.

2. Open \GPIO, then \GPIO_EXTI folders.

3. Open the project with a preferred toolchain. A quick overview on how to open, build, and run an example with

the supported toolchains is given below.

4. Rebuild all files and load the image into target memory.

5. Run the example: each time the USER pushbutton is pressed, LED1 toggles (for more details, refer to the

example readme file).

To open, build and run an example with the supported toolchains, follow the steps below:

•

EWARM

1. Open \EWARM subfolder under the example folder.

2. Launch the Project.eww workspace.

Note:

The workspace name may change from one example to another.

3. Rebuild all files: Project → Rebuild all.

4. Load project image: Project → Debug.

5. Run program: Debug → go(F5).

•

MDK-ARM

1. Open the \MDK-ARM subfolder under the example folder.

2. Launch the Project.uvprojx workspace.

Note:

The workspace name may change from one example to another.

3. Rebuild all files: Project → Rebuild all target files.

4. Load project image: Debug → Start/Stop debug session.

5. Run program: Debug → run (F5).
