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...
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...
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...
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...
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...
I have the zip file for X-CUBE-SBSFU. But I don't know how to add it to STM32CubeMX. I tried install from local on embedded software packages manager. But it did not work.Thanks!
We are developing an application where the host controller will drive two radio modules.But Host controller software should have MISRA 2012 compliant SDK with RTOS support and should support FIPS-certified crypto library.Do anyone can help us to find...
I am use this code for write page with disabling WRP:FLASH_Unlock(); if( FLASH->WRPR != 0xFFFFFFFF ) //WRP is active for any pages { FLASH_EraseOptionBytes(); NVIC_SystemReset(); //according to the manual } if( FLASH_ErasePage( address ) != FLAS...
HelloSince the STM32f42xx series has no intial value for the CRC I'm wondering if there is a way to stop a crc calculation (store the DR value) and resume it by writing the DR register with the stored value and some calculation??Something like this:c...
