Hello all.I have a question about how to use KMS_GenerateKeyPair() function. There are no examples in the code, and API description is not really enough for my little brain. Could somebody provide me an example on how it should be used? What kind of ...

Hello all,Quick question. Why does Secure Engine (SE) consume so much RAM for projects supporting KMS and X509? In sample projects, by default it's around 120 [kB] of RAM assigned for SE. For purely "building" purposes we decreased it down to 36 [kB]...

Hello all,In both files sfu_kms.h and sfu_interface_crypto_scheme.h there is a header guard called SFU_KMS_H.sfu_kms.h:sfu_interface_crypto_scheme.h:Is that a bug or intentional decision?

Hello all,I've encountered an issue while porting 2_Images_KMS B-L4S5I-IOT01 project onto STM32F756ZGTxx.My build fails while compiling nvms_low_level.c file:Source of the issue is FLASH driver for STM32F7, which is different from STM32L4. Do you hav...

Hello all,I'm trying to build B-L4S5I-IOT01A, 2 Images KMS project and I'm encountering the build issue related with missing function definition for KMS_LL_Finalize(). Build fails during linkage phase.Is that issue related with the wrong version of K...

That fixed the problem.Of course I've encountered another one later, but that's a different story related with CA_ECCkeyGen().

Regarding debugging capabilities - yes, I'm aware of a need to change optimization level, the thing is that we don't have enough space so I had to operate on what was currently available. Regarding the main issue though, that looks like potential sol...

I would like to refresh the topic.So I've put such a code (which is basically the copy from example):void generate_ecdsa_keys(void) { SE_KMS_Initialize(NULL); CK_SESSION_HANDLE session_handle = 0; CK_SLOT_ID slot_id = 0; SE_KMS_OpenS...

Much appreciated! That's what I needed.

Yeah, usually that's true. But we've narrowed down the issue to the SysTick function, which halts counting. Right after jumping to that function, HardFault is triggered.
