X-Cube-Crypto Library CubeMX Help

I downloadedX-Cube-Crypto Library from the email and i have the zip. Issue is that i cant seem to find anything that would install it into the CubeMX software. I can browse the zip and see the files and examples included but when i try to install new libraries on CubeMX from local it says ''This Package version is not managed on this version of STM32CubeMX''.

My version is 4.0 for CubeMX. Is there a way to install this lib so that CubeMX is able to create the necessary C source files when project is generated? Question 2 is about the fact that System Workbench is missing from the examples, and support for the F7 series. Is there a plan to add that anytime soon? Thanks Andriy #!stm32-!cubemx-!stm32-stm32f7 Note: this post was migrated and contained many threaded conversations, some content may be missing.

Hi yarema.andriy,

1- The X-Cube-CryptoLib isn't supported in CubeMX now. Your request is shared internally for farther investigation and feasibility analysis.2- SW4STM32 isn't supported only in the examples available under STM32CubeExpansion_Crypto_V3.1.0\Fw_Crypto. However examples under STM32CubeExpansion_Crypto_V3.1.0\AccHw_Crypto support it even for STM32F7.3- What do you mean by ''support for the F7 series'' in your question. What is missing for F7?-Mayla-

The release notes for the HW acceleration specifically only mention support for ''

STM32F756G/STM32F746G 

device 

and STM327x6G-EVAL revA''

The release notes for the Firmware library specifically only mention support for ''

STM32756G-EVAL/ 

STM32746G-EVAL 

boards RevB''

I guess i was looking for a master list of all of the supported boards as well as chips since its good to be sure the crypto library 

doesn't

 have some hidden limitation for the chip we use.

Hi yarema.andriy,

Any STM32F7 device is supported by the library.The boards in the release notes are the ones used in the examples, no limitation on supported devices for the .lib.-Mayla-

I tried the libraries in the examples 

under STM32CubeExpansion_Crypto_V3.1.0\AccHw_Crypto but I get an error:

How do I resolve this?

It suggests a mismatch between the cpu/fpu options between those used to compile the project and those used to compile the library.

I would look at the float ABI, hard vs soft, etc.

-mcpu=cortex-m7  -mfloat-abi=hard  -mfpu=fpv4-sp-d16

You need to compile with FPU option in Hardware  (VFP)  activated in your script  or adapt it with  the right library we provide. with _FPU.

See  Release_Notes.html

Cheers,

I have the flags

-mfloat-abi=hard -mfpu=fpv5-d16

and selected the 

_FPU library, but it still fails.

Thanks.

The error suggests the library was built without FPU support, or perhaps a prior version of the linker.

The error also suggests the expectation of the SOFT ABI, where parameters aren't passed in FPU/VFP registers.

Hi to everyone,

I'm not sure but maybe this could help to you:

The example was made with software acceleration but it's almost the same for hardware...
