I have a project based on an Stm32F767. If I load the hex file and then manually enable readout protection to level 1 with the STLinkV2 utility, the board fails to begin to execute code after reset. Why? What is the correct way to use this feature?
I have a strange issue with my Stm32F767 project. We've seen with some boards randomly RDP will be enable to level 1, and BOOT0/1 are set to 0xffff. ESD seems like a potentially likely cause, but is there really enough energy in an ESD event to cause...
Hi ST community,I have a fully functional application on my STM32L072. The problem is when I tried to enable RDP, nothing works anymore.After flashing the application I tried to connect with ST-Link, the option bytes are set correctly and it is not p...
IAR would fill unused flash and optionally append a crc to aid with the integrity check some of us need to do for regulatory compliance But since IAR's been replaced what provisions are in Atollic to fill unused flash and optionally append a crc? Is ...
We are using a STM32H7 microcontroller for our project ans would like to use the HW CRC embedded in the Flash module.We are designing a custom bootloader that will calculate the CRC and then write it in a reserved section of the flash. Since the devi...
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 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...
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 ...
Posted on February 28, 2017 at 13:05Hello All,I have been trolling across several forums in order to be able to read protect my stm32f334 flash memory from within the code. I tried to use the hal functions provided in the stm32f3xx_hal_flash and stm...
Posted on January 25, 2018 at 06:42I am using ♯, where I tried to calculate the 32- bit CRC of my flash using ♯ register.How I can ensure if the CRC calculation of my flash is correct.CRC Configuration I used is :hcrc.Instance = CRC;hcrc.Init.Defaul...
