Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I've run into an issue with the section of the UserApp linker script which ensures that the binary size is a multiple of 16 bytes:.align16 : { . = . + 1; /* _edata=. is aligned on 8 bytes so could be aligned on 16 bytes: add 1 byte gap */ ...
I have flashed the SBSFU application with write protection enabled for flash address 0x08000000. After that, I am unable to erase using jlink commander.exe as well as by IAR->project->Download->erase.STM32H743 has SWD interface and i am using jlink ...
I'm trying to enable secure boot for general purpose ARM microcontrollers. Based on my research, secure boot starts with a Root of Trust (ROT). Usually this ROT is hardware based, which means that the microcontroller should have a dedicated immutable...
In previous development project we were able to place several variables with a magic number and checksum of the application at the end of the interrupt vector table that the bootloader could use to check if a valid application existed.Since the STM32...
Hi,I ran the SBSFU example of STM32CubeU5 following what is in the readme file without any problem. Then I disabled TrustZone but I cannot run the projects made with STM32CubeIDE, verification of the downloaded firmware fails. If I try to erase the f...
Dear Sir.I am using the example TFM_Loade_Non_Secure , It compiles I set for Download NonSecure App Image , when I send any file*.elf with TeraTerm.File,Transfer.YMODEM.Send , then the programreply with "Abortes by user".Please Advise
Hi,I want to know a properly way do to that.If i use standard configuration I run hard fault as soon as DMA start (linklist mode) (HAL_HASHEx_SHA256_Start_DMA).I put Fault Analyser details Source/Destination secure bit are set before calling this fu...
Hello all,I am working on the STM32H753 Evaluation board and I have a software architecture with an SBSFU running in the internal flash, that jumps to the External NOR flash to execute the user application (Download and Active slot in External NOR fl...
Hi,I have a custom board built around an STM32U585AII6 that utilizes RDP level 2 to prevent debug access. In the firmware I provided keys to allow for regression from level 2 back to level 0 and have been able to do this regression through the Cube P...
I'm running SPI with DMA and CRC enable between two stm32, slave is stm32f415 MCU.Sometimes it appears that data received is corrupted whereas CRC check gives no error. For instance (polynomial used is 0x1021)Normal behavior:3 words sent: 0xAAA0; 0x0...
