how to get rid of STM32 Secure Engine , but still using STSAFE-A110 to connect to AWS.

[jiangpen]

I just start a project to connect STM32H7 device to AWS IoT using STSAFE-A110 , and I am not doing the secure booting.

I have couple of questions

1) STSAFE-A110 has a ST CA certificates in in zone 1, so my understanding is to retrieve this certificate and register to AWS IoT, this device should be authenticated. am I missing anything?

2) Currently the STM32 demo project mix bootloader project with main application . Bootloader build a se_interface_app.o for application to link. I understand it is for demo and safety. My question is if I only want to do the AWS IoT authenticate, how to get rid of the STM32 Secure Engine /bootloader part?

thanks a lot

Hello,

I guess you are using X-CUBE-AWS 2.2.0 package ?

you mention STM32H7 and STSAFE. The STM32H7 example in X-CUBE-AWS doesn't use STSAFE. Only the B-L4S5I-IOT01A example use STSAFE. So are you using a STM32H7 or a STM32L4S5 ?
