Hi,I'm working on a project that needs AES256 encryption, I requested the X-CUBE-CRYPTOLIB software, but it's being validated by STM32, my question is, why does this validation exist? Is there any criteria for them to make the software available? Wha...
I have an undefined reference error to several secure engine functions, for example SE_APP_GetActiveFwStateI have read this thread:https://community.st.com/s/question/0D53W000017PGUKSA4/how-to-call-secureengine-functions-from-my-applicationAnd what I...

Dear all,For an IoT project I would like to run the demo of the AWS package provided by ST but for some reason I could not manage to debug the demo project.To do so I have downloaded the X-CUBE-AWS_v2.0.0 package and used the following ressources : S...
Currently I write locked the first few sectors of my STM32U575xx. However I would also like the unlock the write protection. Since both J-Link and the ST-Link cannot do this I thought about writing a small application and run it from RAM to reset the...
According to the integration guide (an5056) it should be possible to use the flash memory to store user data (chapter 8.2) . However, when turning on the MPU protect define the controller goes into a memory fault when accessing the eeprom for reading...
Dear allI want to check flash integrity with CRC checksum – IAR workbench has built-in features to calculate and add the CRC to the firmware.Under STM32CubeIDE I use a post buildsrec_cat.exe firmware.bin -binary -stm32-l-e 0xEFFC -o firmware_withCRC....
Hi,I have seen, that for the bootloader with just one image, it is only possible to use the YMODEM with UART for updating the firmware with the SBSFU. Now what I'm am concerned about is, that the YMODEM seems not to be very error tolerant. So, what f...
