Cryptographic Library VFP support on STM32F7

[Russeree]

Currently working on a Bitcoin hardware wallet on the STM32F7 Discovery platform. I wanted to use the cryptographic library to secure information stored in the EEPROM as well as perform hashing functions.

VFP is not supported in libSTM32CryptographicV3.0.0_CM7_GCC_ot.a

Is there anybody that works at STM that would compile an object file with GCC and DM me with a copy.

Where:

Floating-point unit = 'FPv5-SP-D16'

Floating-point ABI = 'Hardware implementation (-mfloat-abi=hard)'

Mcu = 'STM32F746NGHx'

Board = 'STM32F746G-DISCO'

I have seen this done before here...

Found the solution for F7 users.

Download patch 3.1.3 for the crypto lib and use the libraries for the H7 series chip.

The lib you are looking for is 'STM32CryptographicV3.1.3_CM7_GCC_ot_fpu.a'
