I have made a FUOTA project and I want to add security to it. I found SBSFU but I see that they must connect the ship in order to update it, and that's not what I want.So my question : is it possible to do a FUOTA with a SBSFU example ? is so how ?
Hi, i am looking for a small MCU with ARM trust zone, ROT, SFI and other security features similar to STM32L552.also fast SPI timing req similar to 401 family ( 401 reference only for timing)STM32F401CBU6, does not have the mentioned security feature...
When I compile a simple programm, using the CRC feature I get the following warning:In file included from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal_def.h:30, from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal_rcc.h:29, ...
I'm trying to become familiar with the security options for STM MCU's before picking an MCU. Where is the best place to learn about what security options exist, what they do, and how/if they impact the price of the MCU? Does a table exist that compar...
In the eLearning course 'STM32L4 Training' (community.st.com - Academy) there is an error in the content : when you open the section 'STM32L4 training: 02.4 - Hands-on CRC unit', it actually plays contents about I2C, not about CRC. Please correct thi...
I tried disable ROP level 1 to level 0 by ST-LINK Utility and STM32CubeProgrammer, but it is not success.Thanks in advance.
Hi i have a STM32G474. I want to build a pmbus on that. The stm has a default CRC32 module.In pmbus for the pec calculation crc8 is using. Can i change my default crc32 module to crc8 for the usage on pmbus?
The SBSFU framework allows users to employ multiple image signing keys, ECCKEY1, ECCKEY2, and ECCKEY3.Is there a method to blacklist ECCKEY1 and replace it with ECCKEY4, which may be transmitted via a key replacement update package if the private key...
We have STM32H755XI6 Controller, and we trying to incorporate the secure boot in our current secure boot with RDP level 1 and secure user memory (HDP protection) but our controller is getting locked up and not able to access (using IAR JTAG and ST LI...
