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...
I use STM32H755ZI to configure the product, but the market is out of stock, can I use STM32H745/STM32H757/STM32H747 instead?Assuming I'm not using CryptoHash/SFI/SBSFU and MIPI-DSIIs LQFP144 pin to pin?
We would need to implement Secureboot & secure FW upgrade feature in one project.I find both STM32G0B0CE and STM32G0B1RET6 not support RNG.But the blow link shows they both support SecurebootX-CUBE-SBSFU - Secure boot & secure firmware update softwar...
Hi, team.Question about security of the MCU.Is it possible to log illegal access by the debugger in the state of RDP Level 1? Any bits is a available for it?
I am using CubeIDE 1.11.2 with a STM32F3DISCOVERY board and have created an IDE project via the integrated CubeMX GUI.I want to activate read protection via HAL_FLASHEx_OBProgram as well as the write protection for the FLASH area of my firmware (appl...
Hello,I have a B-U585I-IOT02A board and was trying out the TFM Application example from STM32Cube_FW_U5_V1.2.0.After flashing the firmware as instructed, I could successfully run the test application. However, after re-connecting the board, I now get...
Hi All,i have downloaded the STM32U585 firmware package from the official sources and want to implement the TFM SBSFU program code into my development board(U585-IOT2A) using STM32 Cube IDE. The user manual mentions installation not possible using Cu...
The question below refers to L452.I encounter once in a while a random activation of the readout protection.I suspect the code that disables the watchdog operation before switching to STOP mode (as it updates the user option bytes).Can this affect th...
I have a user bootloader I have used across various STM32 parts over 12 years. In production RDP level 1 is enabled and this has always been fine for various STM32F1, F2, F4 based products we have in production, and for thousands of units in the fiel...
