Hi @Jocelyn RICARD GreetingsWe have a query from our support team"known vulnerability in the STM32U5 series related to the JTAG lock when using RDP (Readout Protection) Level 2." Is it advisable to proceed with this implementation, or should we consi...
Working on setting RDP (read out protection) on STM32H750. We are using an external loader to be able to read from/write to external flash. The internal flash only contains a bootloader.1. Setting RDP to Level 1 doesn't prevent reading external flas...
Hello, My project is based on the STM32H753 chip.I Using the STM32CubeProgrammer and try to set the RDP level from 0 to 1, I get the error "Error: Expected value for Option Byte "RDP": 0xBB, found: 0xAA".I only enable the Secure Protection.How can I ...
Hi ST Team, Currently i am using STM32H523RCT6 mcu for one of my project. In this i want to set the read out protection of level 1. Currently i am using below sequence to set the read out protection of level 1 protection.. // Unl...
I am using STM32U585 and I stumbled upon the following problem:If a device is configured with TrustZone enabled (TZEN=1) there is different behavior in the following situations:1. SPI is configured without DMA and CPU is running non-secure code in pr...
Hello,I am using SBSFU on the STM32U5 microcontroller, and I have implemented a function to determine the cause of the system reset by reading the RCC register flags. However, every time I enter the function, it always returns an 'unknown reset' valu...
Hi,I am working with SBSFU on a STM32U575 microcontroller, and I want to use the __attribute__((section(‘.ram2’))) to place a variable in the secure SRAM2 memory section so that the variable can write to it. However, the secure SRAM2 memory is reset ...
EDITED:Resolved, but leaving here for the next person who stumbles into this issue.I'm using the STM32G030K6 and encountered two issues:Errata 2.2.3 - which correctly describes a serious issue when using readout protection level 1: if nBOOT_SEL is no...
Hello to all,I was wondering if there was a way to implement a secure update via USB stick using X-CUBE-SBSFU software.Moreover, the application software would be installed on external flash, custom bootloader immutable in internal flash.Maybe instal...
Hi,I'm using F4 series board (STM32F423ZHT6). also I'm using F4 and scripts say L series - are they compatable?STM32CubeProgrammer version: STM32CubeProgrammer 2.14.0 - This is support SBSFUX-CUBE-SBSFU version: 2.6.2I follow the https://www.youtube...
