Can I use Software Cryptographic Library for STM32H743?

[oleksandr.karbivsky]

Hi. I got Cryptographic Library from ST. I added M4_CryptoFW_2_0_6.a to my project and tried calculate SHA256. But got hardfault when call SHA256_Finish function. Hardfault message is " A precise data access error has occurred (CFSR.PRECISERR, BFAR) at data address 0x40023008". I found that this address is CRC_CR register for STM32F4 series.

Crypto lib last release:

• M4_CryptoHW_2_0_6.a: First official release of optimized STM32 Cryptographic Libraryfor STM32F41x famillies.
• M4_CryptoFW_RngHW_2_0_6.a: First official release of STM32 Cryptographic Library Firmware version with Hardware RNG pheripheral for STM32F4xx famillies.
• M4_CryptoFW_2_0_6.a: First official release of STM32 Cryptographic Library Firmware version for STM32F40x famillies.
• M3_CryptoHW_2_0_6.a: New official release of optimized STM32 Cryptographic Libraryfor STM32F21x famillies.
• M3_CryptoFW_RngHW_2_0_6.a:  First official release of STM32 Cryptographic Library Firmware version with Hardware RNG pheripheral for STM32F20x famillies.
• M3_CryptoFW_2_0_6.a: New STM32 Cryptographic Library Firmware version release for STM32F10x and STM32F3xx.
• M3_CryptoFW_L1xx_2_0_6.a: New STM32 Cryptographic Library Firmware version release for STM32L1xx famillies.
• M0_CryptoFW_2_0_6.a: First STM32 Cryptographic Library Firmware version release for STM32F0xx famillies.

So, Is it real to use this soft crypto lib for STM32H743?

ST ties the library to STM32 parts by testing the CRC generator is present. I think one would need to patch that or push for an F7 and H7 variant of the library. ​
