最开始用stm32的flash保存数据的方法都是用原子的例程,STM32F1的话,原子的方法大概是创建一个1K或者2K的缓存,修改数据的时候,先把该扇区的所有数据写到该缓存,然后查看是否需要擦除整个扇区,一般在一个地方写的话,必须要擦除,要想不擦除,就需要一个变量记录下一次要写的地址,和数据一块保存。STM32F4的话,因...
1. 确保您的硬件支持较高的擦除速度。检查 SPI Flash 芯片的数据手册，了解其性能指标。2. 检查 SPI...
我代码运行启动是使用的STM32f407内部flash,我烧录完程序运行起来后,代码区占内部sector 0-4扇区。我现在需要在程序运行期间在线升级软件。但是我用FLASH_EraseSector函数擦除0-4扇区时,卡死在FLASH_EraseSector函数里,具体问题在:执行FLASH->CR |= FLASH_CR_STRT;这个语句后就卡死。但是我擦除5-11扇区测试都...
The flash sector size is 32kB, so sector 15 has range 0x78000-0x7ffff. When writing the data, J-Flash erases sector 15, and part of the code is lost. We solved that for GDB by using the J-Link command "SetFlashDLNoRMWThreshold = 0xffffffff", and I want to do the same for J-...
I am using MIMXrt1020 evk .I want to erase sector number 593. But whenever I enter in this instruction flexspi_nor_flash_erase_sector(EXAMPLE_FLEXSPI, 593 * SECTOR_SIZE); my controller goes into fault. Please suggest me the solution Tags: flexspi mimxrt1021 nor erase sector erase 0 ...
Describe the bug I am facing a similary problem with my disco_l475_iot1 board which has stm32l475 MCU. I am using mcuboot for updatehub app. I am not able to erase flash memory partition. A clear and concise description of what the bug i...

When the number of defects in a Flash sector becomes large, the whole sector is remapped. Yet another improvement is the use of a write cache to reduce the number of writes to the Flash EEprom memory, thereby minimizing the stress to the device from undergoing too many write/erase cycling...
Describe the bug I'm unable to use cargo-flash, probe-run, and cargo-embed due to the below error while using a Jlink EDU Mini with a feather M0 proto Caused by: 0: Failed to erase flash sector at address 0x00000000. 1: The execution of ...
