Has anyone managed to get the STM32 hardware CRC on STM32F7XX to match the output of srec_cat.exe when using the -STM32_Little_Endian flag?

srec_cat.exe has a flag -STM32_Little_Endian described in the srec_cat manual as "These filters many be use to generate the CRC used by the hardware CRC unit on the STM32 series of ARM MPUs.". I can successfully append a CRC to my firmware file using...

STM32H7 Flash-embedded CRC HW calculation

We are using a STM32H7 microcontroller for our project ans would like to use the HW CRC embedded in the Flash module.We are designing a custom bootloader that will calculate the CRC and then write it in a reserved section of the flash. Since the devi...

CRC32 questions

Hi,I have a general question regarding CRC32 for data read from flash. For example I am reading 2048 bytes of data total 512 bytes chunk each time. My question isdoes it make any difference if I check CRC32 for every 512 bytes read or after read of 2...

readout protection cracked on STM32

Posted on January 08, 2018 at 10:21 Am I correct that readout protection has a major issue and is not working at all? Are all STM32s affected? Any comments on this from ST? See here: https://www.aisec.fraunhofer.de/en/FirmwareProtection.html ...

AES 256 GCM Decryption on STM32L562

Hello,I am trying to decrypt some data on the L5. The data below can be fed directly into a python crypto library and get a valid result. I am trying to understand the 32-bit alignment requirements of the L5 as well as any possible byte swapping ne...

For a new line of products, we are considering STM32F750 but it lacks on-the-fly decryption support. Is there a new line of microcontrollers planned that matches the spec of STM32F750 but includes support for on-the-fly decryption

We need a powerful M7 core running at high speed + GPU support for TouchGFX. It seems that STM32F750 is a perfect match, apart from the fact that it is missing support for on-the-fly decryption (OTFD). As we would like to use external flash memory an...
