No CRYP in project configurator

[mkrk]

Why is there no CRYP (Cryptographics) peripheral enabling/configuration option in project configurator (CubeMX/CubeIDE) for STM32H747 ? I tried v1.15.0 and v1.16.0

It does not show up:

But it exists in register callback list:

And it exists in H7 HAL driver library: https://github.com/STMicroelectronics/stm32h7xx_hal_driver

PS.
The project is already using STM32 Cryptographic library but there are strange problems (long story). I want to see the source code and understand what's going on. Pre-compiled library does not allow it.

I also found this post where somebody has same question but different solution.   https://community.st.com/t5/stm32-mcus-security/problem-implementing-cryptographic-library-in-stm32h747/td-p/149901
I want to use peripheral through HAL, no closed source.

Hello @mkrk 

This is only available for MCUs that feature Cryptographic acceleration (such as the STM32H757 that has exactly the same features but add the Cryptographic accelerator). For the STM32H747, you may can use the X-CUBE-CRYPTOLIB (the one used by the client on the post you mentioned) and include it to your project directly following this article.

Best Regards.

Hello @STTwo-32 

I see... reference manual is the same for H747 and H757 so I naturally expected H747 to have CRYP. My bad.

The project is already using X-CUBE-CRYPTOLIB, but it has strange issues and that's why I was thinking about using peripheral directly. I have to think whether to ask about those issues or use some alternative.

Thanks!

Here you need to refer to the related datasheet especially "features and peripheral counts" table not to the reference manual as the latter is common to many devices.
