I want to know how to access data which is protected in firewall for the STM32L073

[yweic.1]

I set the start address about RAM is 0X20002000, and disable shared but execution.

Than, I set a function which data is 0x20002004 to change the protected data.

when system enter the function, it will reset.

Hello @yweic.1​ ,

I suggest checking this application note AN4730. It should help!
