Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I thought this would be simple, open up the STMCubeProgrammer, connect to the programmed device, select RDP, select BB read protection (CC means the MCU can never be reprogrammed so no user-done code updates!!) and then Apply!But no, the board screen...
Hi, we have to use a secure bootloader for STM32U585.I have reading documentation about SFI and SBSFU and I am confusing.1) Is theresomewhere a porting of SBSFU on this device?We want to use a custom secureBootloader that only check update inside e...
Hello supportTeam,Have a good day.we are working on the STM32U585ZIT6Q controller. I turned on the trust zone option in this controller.I have a few questions about the priority of peripheral interrupts, which I explain below.1. What happens if an IS...
Hello,Im using STM32F723 and using the Cryptographic Library (https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Security:Getting_started_with_the_Cryptographic_Library).When testing basic cmox_aead_encrypt and cmox_aead_decrypt example it works fine.B...
Hi;I am using STM32U585ZIT6Q controller in my current project. I am enabled Trust Zone option. I am using dual bank option too.I have created two partition in both bank as in attached image.When i try to update firmware using STM32 cube programmer, a...
I have recently adapted the STM32H753ZI-Nucleo SBSFU project to run on the H745ZI-Q, but only on the CM7. I am trying to adapt the project to handle another active image slot dedicated to the CM4, but I am having a bit of a problem with the firmware ...
Having difficulty gaining access a peripheral region in the bootloader and could use some suggestions.In the bootloader we need to MAP the address space described below, this address space works correctly in the application but not in the bootloader....
I have a large block of data to encrypt (about 200 Kbytes). I don't care about preserving the input data and I'd like to save memory.Can t I set the output buffer pointer to the same value as the input buffer pointer using the HAL AES encrypt functio...
The board connects but when I build and run the project, the light does not blink as it says it should. Also, I'm using mac, how do I import cryptolib into an existing project? I followed this instructions and this wiki but it's not working.
Hello everyone,I'm trying to adapt the STM32CubeU5/Projects/B-U585I-IOT02A/Applications/SBSFU at main · STMicroelectronics/STM32CubeU5 · GitHub for another U5 chip. I'm trying to print the non secure app with uart but I am stuck at "Jumping to the fi...
