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...
Hi,I'm using STM32F423ZHT6 MCU board. I want to implement the FOTA as well as Scure Boot on my EVAL board. But I don't have much knowledge about Secure Boot. So, I refer https://www.st.com/en/embedded-software/x-cube-sbsfu.html and AN5056. The SBSFU ...
I'm struggling with entering RDP level 1 using the ST Cubemx code examples. I am stuck with OPTVERR bit set and never being successful in getting FLASH_OPTR RDP bits set to 0xBB AND written into flash so that it boots using 0xBB and not 0xAA. (I ca...
Hi, I followed all the steps from the UM2851 documentation about TF-M application. At point 10.2 I ran the regression.sh script, with the below output: regression script started Regression to RDP 0, enable tz -----------------------------------...
