I working with the STM32F446-microcontroller and I need to upgrade firmware and change the option bytes on it using the built-in bootloader (en.CD00167594.pdf, AN2606) using SPI-bus (en.DM00081379.pdf, AN4286). I am able to successfully modify all op...
I am working on STM32L151QD MCU. I want to implement CRC feature in my application using STM hardware CRC block.i am trying below steps to configure HW CRC:uint32_t crc; uint32_t t_buffer[4] = {1,2,3,4}; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_CRC, ENAB...
I'm aware that the STM3240G-EVAL doesn't have a hardware crypto processor, but is it possible to create a software algorithm to do the encryption? Possibly using the X-CUBE-CRYPTOLIB library?
Hello. AllI'm using STM32L151 MCU, stm32 crypto library v.3.0.0.I implemented CMAC according to the sample code but it returned "AES_ERR_BAD_CONTEXT". I could not find any reason.. please let me know to solve this problem.!!Here is my code for CMAC e...
I am trying to use the hardware CRC built into the embedded flash module. When I use the start and end addresses and kick off the CRC, the processor halts and I have to do a full flash erase to get it back. Are the start and end addresses relative ...
I have been using the STM32 serial bootloader, instead of coding my own bootloader, for a while now. But lately I wanted to protect my code, so I tried to enable readout protection (RDP) level 1. This is meant to prevent the user to read the flash. H...
Hi everyone,we have a bootloader that writes new application code to the flash bank 2 in an STM32H7 and afterwards swaps the banks to execute the new code. The procedure for swapping is something like this: unlock OPTLOCK set SWAP_BANK_OPT set ...
