Hi Team,I've updated only the UserApp RAM region. I came across a post stating that SBSFU and the application are independent, so I followed that approach. However, after modifying the RAM region and uploading the sbsfu.bin file to the MCU, I get an ...
Hi,We are using an STM32U585 with the application running from external flash, on an octospi bus. We are also using external SRAM. The external memory architecture on our board is heavily influenced by the B-U585I-IOT02A design (same ports, slightly ...
Hi there, I'm under mass production with yours STM32L051x8 device. I use the internal EEPROM to keep some data. Note that is not en emulation eeprom on flash, is just 512bytes on internal EEPROM. In addition, I protect my code with ReadOutProtection ...
I am conducting operational verification of the sample application of X-CUBE-SAFEA1 by connecting NUCLEO-L476RG and X-NUCLEO-SAFEA1B.I have some questions regarding the operation of the sample application "STSAFEA1_WRAP_UNWRAP".My questions are as fo...
Hello,Thanks for all of the help so far. Another question, this one regarding SFI process for the STM32U5 series. In AN4992 section 3.3.1 for STM32L/U/W series, it describes a secure bootloader that is split into 2 parts, one of which is responsible...
Dear ST Community,I am currently using the STM32F407G-DISCOVERY board for my project and would like to implement the SBSFU (Secure Boot and Secure Firmware Update) bootloader on this board. However, upon reviewing the X-CUBE-SBSFU package, I noticed ...
Hii Sir,Recently I have got Nucleo-H563ZI nucleo board and i was trying to do programming for blinking led present on the board with the trust zone activated, but i am unable to get how to do it.The process i follow is;1) Created new stm32 project ->...
Hello all,I have been working on a bare metal Rust implementation of the PKA engine in the STM32WBA55CG microcontroller. So far, I managed to properly initialize the PKA engine, and run both modular addition and subtraction by writing and reading the...
Hello,We are using an STM32H573 with the Secure Manager provided by ST running in the secure environment. In the non-secure environment, we are calling PSA functions. These calls work before ThreadX is launched but fail afterward.According to the pag...
Greetings,I would like to know, in summary, what are the key main differences between RDP (ReadOut Protection) and PcROP (Proprietary Code Readout Protection), which one is safer and use cases.Thank you!
