Hi, good morning, sir/madam.We are using a STM32F423ZHT6 MCU for Smart Lock in our project.We have some security purposes for our lock and need security boot options.So please clarify this MCU has secure boot options. If this MCU has secure boot opti...
Hello We are testing the SBSFU project on STM32U585 released in the cubeu5 project and came to see that the secure project uses 14kb of size and non secure approximate 1.2MB. Our requirement is to add some modules into the secure area and we need to ...
Hello, I am confused in finalizing a secure chip for my iot gateway(linux). I read all the documents for ST SAFE-A110. My gateway has an mqtt broker which is bridged to another broker in cloud. In order to Implement TLS for mqtt i need to provide key...
Is this the right way? if (FLASH_OB_GetRDP() != OB_RDP_LEVEL_2) { HAL_FLASH_Unlock(); // Unlock the flash memory HAL_FLASH_OB_Unlock(); // Unlock the option bytes *(__IO uint8_t*) OPTCR_BYTE1_ADDRESS = OB_RDP_LEVEL_2; // Set RDP2 HAL_FL...
Hi,I've developed a custom board and I want to leave an encrypted signature using the STSAFE-A110 chip. However, I'm coding my board in Python, and I'm having trouble figuring out how to interact with the chip. I found the "STSAFE-A complete set of A...
Hello,I would like to be able to debug the SBSFU application of the STM32U5 microcontroller series. What steps do I have to follow to be able to do it? Thanks in advance
Hello,I am using the stm32u5 SBSFU application and I am trying to implement my own 64 MHz clock. But when I change it from 160 Mhz to 64 Mhz the application does not work. Can the SBSFU clock work with less than 160 MHz or does it have to work only w...
Thissuggests that one cannot execute code from SRAM. Is that really correct?Also there is ambiguity on whether the OTP area (512 bytes plus the control block) is readable in RDP2. Why say "512 bytes" and not just all-OTP?The OTP area must remain usab...
Hello, I have a ARM Keil MDK project with STM32H563ZI and want to protect it against readout. So I want to use the Debug Authentication. The trustzone is not activated. The first time programming is done over UART and then over USB by an own tool and...
STM32U585xx SBSFU source code examples do not build properly.Nice to meet you.If you download and check the en.stm32cubeu5-v1-6-0.zip file (including patch), it contains an example for STM32U585 SBSFU.If you try to build the 'SBSFU' example for 'B-U5...
