Hello, I am using STM32F103c6 cortex-m3. I am using 100 micro controllers in various boards. In some around 10 micro controllers, I have seen a issue of option bytes getting corrupted. Even though I am writing 0xA5 to RDP to remove read protection wh...
I am trying to run ECDH p384 operation on STM32H753.Using the STM32 Cryptolib 4.5.0, I get the CMOX_ECC_ERR_MEMORY_FAIL error during the operationI increased the stack size to the maximumI was able to run this using mbedTLS + hardware blocks like RNG...
Hi, I managed to enable TrustZone by setting the TZEN-bit to 1 like soSTM32_Programmer_CLI -c port=SWD -ob TZEN=1But I can't seem to manage to turn it off the same way. I've tried doing it from the graphical interface as well, with the same results. ...
Hello!Using h563zi I am trying to update the second bank firmware using an application that has a Secure Part (sectors 0-9) and a Non Secure part with Trust Zone enabled. For easier maintenance the update is done from the Non-Secure part.Settings:SEC...

Hi @Jocelyn RICARD,im trying to enable the secure user memory on my custom bootloader for STM32H755 and STM32H7B3 MCUs.The bootloader is on the first bank and the app on the second bank. The secure user memory is enabled successfully on bank 1 but j...
In current, I am using the NUCLEO-H753ZI of STM32CubeExpansion_SBSFU_V2.7.0 demo project.Hardfault error happens in SFU_SE_STACK_Clean api in case SFU_ISOLATE_SE_WITH_MPU is not used like "#undef SFU_ISOLATE_SE_WITH_MPU"the value of sp is 0.Please le...
Hello,I try to implement a tamper detection for my project. In general, it works. When the device is only powered by a coin cell and a tamper is detected, the backup registers are erased and unfortunately also the backup RAM. When the device is power...
I would like to increase the code readout protection level from 0 to 1 programmatically in an STM32G030. I must be doing something silly and if anyone sees it, I'd be grateful. I've stepped through it with the debugger and the flash and option byte...
Hello,It seems to me that the wiki page: https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Security:Secure_storage-SAES_key_wrapping_for_STM32N6 is unavailable as I get the message: "Page not found".I tried searching for it, to no avail. Is the relate...
