Hi @Jocelyn RICARD Greetingswe are working on the STM32u585 TFM Application and are facing issues when running the code. the issue is after dumping the code using the TFM_Update.sh script first time every operation is normal, but while running for th...
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,I have a use-case with a soldered battery, which I can not power-cycle after programming, however I have to set option bytes to restrict Flash reading.I found online that going into STANDBY mode or rather, returning from STANDBY mode, would upd...
Hello everyone,I am working with the STM32H7B3 and after enabling the secure user memory, i am not able to connect with the debugger anymore:For testing if secure user memory works, i put a "secure_function" in a section at the end of my flash, then ...
Hi, I just accidentally modified the PRODUCT_STATE to provisioning and not able to recover.So, I tried to do the OBKey Provisioning and use DA to regression back to Open State.I've created my OBKey:However, provisioning always failed.Is there any oth...
I am worried about the data that i send through the STM32WL55JC if any outsider with the same board and using the same frequency in receiver mode ,can also get the data that i am sending through the transmitter using same frequency ,How do i secure m...
Hi Good day, Trying to understand the CRYPTO module for MAC generation, particularly AES CBS MAC. Which algorithm mode i have to choose?, found AES CBC not AES CBC MAC.
Hi,I´m trying to implement a simple ECDH test by implementing the functions from the Cryptographic Library V4.2.0.There are two persons A and B generating a pair of private and public keys. The keys are generated by the cmox_ecdsa_keyGen(...) functio...
Hi, how to do signature verification in stm32u575 with RSA-2048?
Hello everyone,i am trying to enable the secure user memory on the stm32h743 using the x-cube-sbsfu project and have the following problem:After activating the security bit, the value of the OPTSR_PRG flash register is not changing, so the security b...
