If the Read Protection is set to RDP Level 1 in the Option Bytes, does the above claimed vulnerabilities affect STM32F7xx or STM32H7xx MCUs?
FLASH memory protection is different between STM32G070 and STM32G071.But there is no stm32g070 in the sample project of x-cube-sbsfu package, only stm32g071.Based on project NUCLEO-G071RB, I commented out two protections and compiled them. I wonder i...
Hi,We are using STM32F769BIT6 based system for our product. We like to enhance the system with security.Is it possible to add secure boot and encrypted boot to the system without any hardware modification?
Hi everyone,I am using STM32L4A6 with FreeRTOS running on it. I integrate SBSFU according to UM2262 and AN5056. After jumping to application, the firmware triggered Firewall reset when calling osKernelStart() .I already turned SysTick off before jump...
I'm going to play with "Secure User Memory" and RSS feature (explained here) on STM32H753 ,and wonder if it is possible to reset the secure mode using debugger.Of course, unless RDP level 2 is active.Is there a window of time after power-up for a deb...
Hello, I've adapted SBSFU (X-CUBE-SBSFU) example projects for a STM32L4R9 in single bank (flash) mode. I get a firewall reset when accessing SRAM1 that's outside of the defined protected area. Only a small section of SRAM1 is protected by the SBSFU ...
I am trying out the sample projectSTM32CubeExpansion_SBSFU_V2.2.0/Projects/NUCLEO-H753ZI/Applications/1_Image.I have completed the following build steps:prebuild.pyBuild SECoreBinBuild SBSFUBuild UserAppThe last step postbuild.py (which is SECBOOT_EC...
Hi,I am new the the development and I have been testing the hardware aes module.I have tested against a known vector and the results differ from what is expected, I have checked the test vectors using AES provider in .NET and I get the results I expe...
I have a module that uses the STM32F091RC MCU and trying to connect it with software using C# language.At the first the connection has worked properly, then I've used the CRC32 to verify the sent data but it didn't work.Ive read the "Application note...
Hi,I have (for example) a byte array with the size of 6. Now I want to calculate its crc32 value. The first 4 bytes are no problem - I put them in as word, but what about the last 2 bytes?Thanks for the Help in advance.BRNico
