The question below refers to L452.I encounter once in a while a random activation of the readout protection.I suspect the code that disables the watchdog operation before switching to STOP mode (as it updates the user option bytes).Can this affect th...
I have a user bootloader I have used across various STM32 parts over 12 years. In production RDP level 1 is enabled and this has always been fine for various STM32F1, F2, F4 based products we have in production, and for thousands of units in the fiel...
Hello, I'm a bit stuck and I am not sure what to do so I am asking for your help.Here is the problem :I have a custom board with a STM32WB35 that was working fine for a while. But after multiple (incomplete) boot when I was soldering the battery to m...
I'm using STM's cryptographic library on a STMf412ret6 to encrypt a 16 byte message using a 2048 bit public key generated by the Python-RSA 4.8 library, first result on google for "python rsa".I've verified the key being received by the MCU is identi...
i am enable trust zone and I make one part as secure world and another part as a non secure world using (SECWM1, SECWM2) but forget to enable Dbank as (Dbank = 1) now I couldn't make any changes in option bytesmy question is1.how can I enable dual b...
I set the start address about RAM is 0X20002000, and disable shared but execution.Than, I set a function which data is 0x20002004 to change the protected data.when system enter the function, it will reset.
I have configured the STM32CubeExpanision_Crypto_V4.0.1 folder using the STM32CubeIDE. Within the folder is a main.c file for a SHA256 digest located in ..STM32CubeExpansion_Crypto_V4.0.1\Projects\NUCLEO-L476RG\Applications\Hash\SHA2_Digest\Src. With...
Hi,My project is based on STM32L15xx microcontroller. I know, that internal FLASH Read Protection may be enabled during programming an image by STMFlashLoader with --erp option. My question is: can I compile my image with internal FLASH read protect...
Hello,I wanted to try the SBSFU topic 6 step by step youtube video, i accidentally flash the Userapp.bin with the RDP level 1, (and also with Write protection enable in bank1).I try to change the RDP level back to 0, and also disable the Write protec...
looks like the same issue like in: STM32F423 Generating AuthTag for AES crypto is not working
