NUCLEO-L152RE_2_Images_UserApp post build fails

[jeroenjvdb]

I have the nucleo l152RE board and am trying to use this for following the mooc on sbsfu. It is possible for me to build (in cube IDE) both SECoreBin and SBSFU images. however, when building the UserApp it fails on the postbuild script. During build, I can see the UserApp.elf being created and showing up in my file explorer, but when the post-build script fails, the .elf file is also removed from my system.

According to the build output, the file "OEM_KEY_COMPANY1_key_AES_CBC.bin" can not be found, but I can see it in my directory structure.

I have the following build output:

Hi,

I just tried the compilation but couldn't reproduce your issue.

Could you try extracting again the whole L1 project from the zip file, import the project in new workspace and compile?

Also, if you go in directory with command line

Projects\NUCLEO-L152RE\Applications\2_Images\2_Images_UserApp\SW4STM32\NUCLEO-L152RE_2_Images_UserApp\Debug

and type

dir ..\..\..\..\2_Images_SECoreBin\SW4STM32\..\Binary\OEM_KEY_COMPANY1_key_AES_CBC.bin

Does it display the file?

Best regards

Jocelyn

hi Jocelyn

I tried unzipping the file again and put it in the Downloads folder (as I did before). This gave the same error as before.

The next thing I tried was putting it inside C:\STM32SecuWS\L4 (like it was done in the course), then it ran succesfully. Maybe the path is too long when putting it inside the downloads directory?

Before I did this, I tried to type the dir command from the debug folder and it displayed the file correctly.

Hi,

yes this long path could also be the issue.

This is an issue that comes regularly but I forgot about it this time :)

Good to see you solve the issue anyway

Best regards

Jocelyn
