Minimal demo of STM32H753 Secure Access mode
Dear experts,I'd like to try the Secure Access mode of H753, but overwhelmed by the SBSFU and SFI documentation.I'm thinking about a minimal test for the "secure user memory" - without SFI, Secure Package Creator etc., or as little as possible:Burn a...
How to append a CRC footer to .hex/bin file with STMCubeIDE ?
Hi all,I am writing an application on STMCubeIDE and i need to append the its CRC at the end of the generated hex/bin file. Is there any shortcut or functionality in order to do that on STMCubeIDE? And if not, how would you suggest me to do that? Tha...
BUG: CubeMX 5.3.0 doesn't generate CRC.c for STM32G474
The compiler cannot find the function MX_CRC_Init()The reason is that STM32CubeMX 5.3.0 doesn't generate CRC.c for STM32G474 when the CRC module is enabled.The CRC.h header is correct generated.This happens only in the STM32CubeIDE with the integrate...
About STM32H7 SPI CRC length
Hello,I need to enable CRC on my SPI communications. My STM32H7 is the Master and it will send most of the times 4 bytes commands to the Slave. I have chosen DSIZE = 32 bits to speed up the processing, since the copy of data to the FIFO is done by so...
Is it possible to download firmware again after trying out the SBSFU projects?
I tried the SBSFU examples (did not change any code) on a NUCLEO-L476RG board and it worked fine. Now I can not use STM32CubeProgrammer to connect the board. Is there any way to download a new firmware ( I mean, a firmware to replace the SBSFU firmwa...
Optimizing X-CUBE-CRYPTOLIB for memory constraint
Hello!I want to use Asymmetric Crypto algorithms like ECC or RSA for my FreeRTOS project running on STM32F051K8. The controller has 64 KB of flash. Since X-CUBE-CRYPTOLIB occupies quite large memory footprint, my FLASH is getting overflowed by the .t...
Setup CRC via STM32CubeIDE 1.02
I am trying to set up the CRC in an STM32L072 to process data from a 1-wire device.In the CubeIDE (editing the .ioc file), if I leave the default values, it will generate an appropriate MX_CRC_Init(void) function.But if I want to set my own polynomia...
Can't reset RDP from level 1 to level 0; Nucleo L476RG
Hi,I was testing with the Nucleo STM32L476RG board, BSP example project FLASH_DualBoot.I made small changes in the example code (LED blink stuff) and programmed bank 1 and 2 several times. I also manually checked/toggled the option bytes BFB2 bit a f...
