STM32 Trusted Package Creator v2.12.0 creates incorrect option bytes which have 8 rows and no "reserved" last row As per AN5054, it should have exactly 9 rows The option bytes csv created from STPC v2.12 This leads to SFI programming failure. Am I mi...
A packet with CRC error has both SUBGHZ_IT_RX_CPLT and SUBGHZ_IT_CRC_ERROR flag set.In stm32wlxx_hal_subghz.c, this leads to both RxCpltCallback() and CRCErrorCallback() being called.https://github.com/STMicroelectronics/STM32CubeWL/blob/main/Drivers...
I have an existing STM32L433 project (CubeIDE 1.8.0) to which I want to add AES functionality via the CMOX crypto stack (https://www.st.com/en/embedded-software/x-cube-cryptolib.html). I am unclear as to where I am supposed to put the .a file, and al...
It seems that 32 bytes (256 bits) is the maximum key size. If so, is there a list of elliptic curves that will work with keys of this size?
Hello guys, how are you?Currently i have an interesting problem happening with my STM32WB5M. I have a project that uses SBSFU alongside with a firmware that uses the BLE peripheral with CPU2 and etc. I don't use the BLE loader, i developed i customiz...
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...
