To secure USB against unauthorized usage while maintaining regular operation, implement authentication and encryption for all USB communication, ensuring only authorized devices or users can access the interface for parameter and log management, open...
Section 6.1 of AN5056 (for X-CUBE-SBSFU) states that the projects are delivered with the highest level of compiler optimizations turned on for size aspects.If the Optimization Level was set to 'None', then how much larger is the generated code expect...
Hello STM32 Community,I’ve successfully built a Zephyr RTOS blinky application for the NUCLEO-H533RE board. Flashing the zephyr.hex using west flash or STM32CubeProgrammer works perfectly — the LED blinks and the serial terminal prints the expected s...
Hi ST team,I am using STM32U5G9 as secondary MCU. It has simple firmware upgrade feature. It would be reset by main MCU and enter system memory bootloader using Boot0 pin. The system memory bootloader would receive upgrade image (application) from ma...
Hi All, Does anyone know how to enable the MCO2(PC9) output after secure manager enabled? its work in project without secure manager and it could be enabled in systemClock config function as below: ,but it's not work any more after secure manager o...
Hi teams,CPU: STM32U0Current RDP level: Level 1OEM1 RDP lock: Enabled.I had set the 128bit OEM1 key to the OEM key registers [FLASH_OEM1KEYWyR ]accordingly, and the written OEM1 key values was verified using their CRC values by reading OEM1KEYCRC r...
Hi,I am trying to send encrypted data between a C# application and STM32 in AES GCM mode.Currently, I am only doing encryption of a known test vector.Key and IV are both all zeros.AAD length is 0.My testvector is: 00 00 00 00 00 01 00 00 00 00 00 00 ...
Dear,For a given HDPL, how many 256-bit AHKs (Application Hardware Keys) can be stored in the option byte keys?And how many of those are:only usable by SAES?usable by software?The reference manual states the following:5.2 FLASH main features:"Up to 1...
How can the debug interface on the STM32H573 be permanently locked via nonvolatile configuration or fuse?The SBS chapter of the manual saysThe debug configuration can be locked thanks to DBGCFG_LOCK in SBS_DBGLOCKR.SBS_DBGCR is then no longer writabl...
Do all the STM32WL series MCUs support STSAFE ? If yes, how it can be done?
