Hello, When I'm learning "STM32 security in practice MOOC". I ran into the below scripts to make raw binary of signature and public key. I thought it was not easy to use and explain to others. Is there a better way to make a raw binary of signature a...

I'm looking for a better way to make raw binary of signature & public key when I'm making a secure bootloader.

After testing the firewall example, NUCLEO-L476RG is resetting continuously even running a simple blinking example with no firewall function.

Re: Hello, I am porting SBSFU to STM32L496 and want to use USB Virtual port to replace UART2, Now SNSFU failed at calling __IS_SFU_RESERVED(); What could be the problem? Thanks
