Hi all,I was hoping someone could advise me on the key storage feature of the part number STSAFE-A110 (STSAFA110S8SPL02).We have a device in the market-place at present which is currently undergoing a redesign. The device itself is a network security...
Hello, What is the status of the OEMKEY1 and OEMKEY2 when the RDP regression happens. Are those keys are also erased ? Thanks in advance.Best Regards,Surya S
Hey,I tried to activate the HDP feature / secure software area on H753 following this documentation HDP secure area for STM32H7B3xx microcontrollers - Application note. I did only activate the security option byte not the secure software area itself....
I followed the secure image tutorials as can be seen in AN4992/AN5054 or in videos made available by ST. The process takes place without errors, as can be seen in the images below (start address is 0x08000000).Smart card is valid and working:However...
Hello all,In both files sfu_kms.h and sfu_interface_crypto_scheme.h there is a header guard called SFU_KMS_H.sfu_kms.h:sfu_interface_crypto_scheme.h:Is that a bug or intentional decision?
Hello,I have not been able to debug any of my TrustZone projects. In order to see what was happening I decided to debug and run ST examples, also with TrustZone implemented, from "STM32Cube_FW_L5_V1.5.0" with the following results:- FreeRTOS_Secure_I...
It seems to be a recurring challenge in the community posts of getting firmware MPU configuration to work with SBSFU. We also had the problem of application firmware hanging when running it with SBSFU. A solution of clearing floating point unit flags...
How to exit safe mode when the security position of the chip is 1 and the protection area of the flash of the new chip is from 0x080000000 to 0x082020000, but the content in the flash is erased，Thank you.
Can the internal TRNG peripheral of the STM32U5MCU be accessed on the STM32U575I-EV eval board?
Hi all,In our project we have enabled the ENABLE_IMAGE_STATE_HANDLING flag and download an image via YMODEM transfer to our NUCLEO-L476RG. However, when we try to validate the image by calling SE_APP_ValidateFw(), our STM reboots and does a rollback....
