STM32L151CB-A not booting from internal FLASH with RDP = BB (Level 0)
Dear all,I have a question regarding the read-out-protection on STM32 L1 series (STM32L151CB-A) and I was wondering, if the same problem occurred to anyone of you before.I am booting from internal flash memory (BOOT0 = GND) and set the option bytes R...
Bootloader + Application Issue - Not working with Nucleo-wb55rg and STM32U585 discovery kit
Hello,I've two STM32 development kit and would like to implement and test the secure boot loader, however it's not working. There is NO serial print after programming boot loader G0_BL.bin load or Application G0_App4BL.bin. I read the location of 0x0...
Using MX to locate IVT in RAM
I am using the STM32F746VET6 which was setup with STM32CubeMX project. In the code it creates I see there's a STM32F746VETX_RAM.ld linker file and a #define VECT_TAB_SRAM to locate the IVT in RAM, but I don't see in MX where I specify that I want the...
How to use SHA1 function in STM32CubeIDE?
I am trying to implement the sha1 function using the cryptographic library offered from STMicroelectronics. I believe I have properly imported the library as per the directions in Security:Getting started with the Cryptographic Library - stm32mcu. Fr...
Is there a user manual for the STM Cryptographic Library V4?
Is there a manual for the STM cryptographic library V4? I know the legacy V3 cryptographic library has a manual (https://www.st.com/resource/en/user_manual/dm00215061-stm32-crypto-library-stmicroelectronics.pdf), but I cannot find an updated manual f...
Resolved! Unable to reallocate Application at other than base address
I aim to load my application at 0x08002000 instead of 0x08000000(base address) and secure the first two sections which will be used to store CRC and other firmware update information.I use a post-build script to calculate the CRC using srecord utilit...
Error in STM32H753 reference manual related to AES-GCM ?
I've found an inconsistency between different reference manuals of STM32 embedding the CRYP peripheral, about the management of IVs in GCM mode:The HAL seems to implement the second solution.Could you confirm ?Best regards
