Resolved! MPU configuration in combination with sbsfu (secure boot and secure firmware upgrade) package.
I'm currently porting an existing project so it can be updated using the sbsfu bootloader project from ST. My userproject is using the MPU to protect the ethernet tx and rx descriptors from ending up in the d cache. However, if i enable the MPU the F...
Factory bootloader CRC command?
I noticed that in STM32FLASH programming utility, there is support for a CRC bootloader command. From what I can tell in the source code and commit history, this command is 0xA1 and was introduced around June of 2014. But from the ST documentation, ...
Is there any way to implement BigNumbers on a STM32F4?
I need to implement some BigNumber math on an STM32F4 (bn.h, conv.h, modular.h). I would like to use functions such as W8_to_Big(), StAllocBig(), and InitBig(). Unfortunately I cannot find any information on how to use these functions. Are there any ...
Resolved! How do you generate public and private keys for RSA?
The user manual (UM1924) says in section 15 RSA Algorithm:There are two structures that pass keys to the functions:•RSAprivKey_stt for the private key•RSApubKey_stt for the public keyAll members of the above functions should be filled by the user bef...
Resolved! Port the SBSFU to STM32F730 in XiP mode
Hi, I just went over the X-Cube-SBSFU material and tried to compile the example projects to get an overall picture of this function.The MCU I used is STM32F730I8 and I am using the STM32F7308-DISCO board.As only 64kB flash is available in STM32F730 s...
CRC16 for STM32F030
I am trying to use the hardware peripheral on the STM32F030 to calculate a 16-bit CRC for a modbus RTU application. But I don't know how to do it.
Protection against code dump from the flash memory (hacking)
Dear all. How secure is STM32 MCUs to prevent hackers from dumping the firmware from the flash memory? I've searched on the internet and on Taobao (like ebay) China and I found there are plenty of companies that claim they can crack and dump the fla...
Does STM32L073RZT6 actually have "128‑bit AES hardware encryption"?
For example, Im looking at the STM32L073RZT6 This documentation from ST states there is "128‑bit AES hardware encryption".https://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/brochure/6c/48/c0/f1/bb/35/4a/b4/brstm32ulp.pdf...
STM32 with Mbed Support and Hardware Encryption?
Is there a list of STM32 based Mbed supported MCUs that have hardware encryption?I'm looking for the cheapest options.Many thanks
