STSAFE-A110

[tobbymathew]

Hello All,,

 I am using STSAFE-A110 with stm32f429zit6 for secure boot, I want sample code / library for the same. 

Also my another query is will I have to sign the firmware using openssl externally. can anyone provide me complete step to finish the secure boot.

Thanks in advance!!!!!

Hi @tobbymathew 

can you take a look at STSAFE-A integration within OpenSSL security stack STSW-STSA110-SSL - STSAFE-A integration within OpenSSL security stack - STMicroelectronics

Hi @tobbymathew,

For Secure Boot on STM32, please reference to the X-CUBE-SBSFU package.

You will find in the UM2262, the STSAFE-A is used only with STM32L4.

Regarding the firmware signing with OpenSSL, this will depends on the FW image you need to sign.

To generate a signature, you will need to use the openssl dgst feature with -sign to generate hash + signature of the image then, you will need to generate the full image with the signature.

Best Regards,

Benjamin
