Errors building TFM example for U545

[Kazimierz Król]

Hi, I'm trying to build TFM example applications from the B-U585I-IOT02A directory to work on Nucleo-U545RE board. THe documentation says it's possible. I have updated the project settings, but I'm getting errors from the STSAFE library:

 

C:/Work/OldCourse/SecureBootTesting_ST/Projects/B-U585I-IOT02A/Applications/TFM/TFM_Appli/Secure/Src/stsafea_service_interface.c:92:51: warning: implicit declaration of function '__HAL_RCC_GPIOF_CLK_ENABLE' [-Wimplicit-function-declaration]

 91 | #define STSAFEA_VREG_GPIO_PORT GPIOF

The problem seems to be coming from the fact that this MCU does not have GPIOF port. Instead of editing the file I would prefer to disable the STSAFE altogether, because I have no intention of using it.

I tried to remove the STSAFE_A110 definition, but then I got more compilation errors.

Also tried to set TFM_PSA_API to zero, but it didn't change anything.

Is there an official way to disable STSAFE?

Hello @Kazimierz Król ,

According to readme, STSafe usage is disabled by default. It should be enabled using PSA_USE_SE_ST flag.

So, I guess this configuration was not properly tested.

You should be able to remove any file related to STSafe from compilation, starting from this stsafea_service_interface.c

Now I didn't check if this was enough on my side

Best regards

Jocelyn

Thanks. I managed to build the example without errors by disabling compilation for:

• stsafea_crypto_interface.c
• stsafea_service_interface.c
• Middlewares/stsafe_a directory
