每个flash bank都有一个对应的控制寄存器来设置上述缓存的使用，但是系统复位后的默认设置已经能适用绝大...

解锁Flash,通过HAL库的函数HAL_FLASH_Unlock实现。 如果是BANK1或者BANK2需要擦除,调用函数FLASH_MassErase,然后等待擦除完成,完成之后关闭BANK1和BANK2的擦除请求位BER1/BER2 如果是扇区擦除,调用函数FLASH_Erase_Sector,然后等待擦除完成,完成之后关闭扇区的擦除请求位SER。
>>不可以,以PFlash Blank为最小单位。例如:将多个PFlash Bank设置为A组,其它的几个PFlash Bank为B组,并且要保证大小一致。需要注意:1.TC3Xxx系列只有一个1M的PFlash Bank,其它PFlash Bank均为3M,如果1M的PFlash Bank使用的话,会导致部分内存的浪费;2.需要关掉Fast Path访问本地的PFlash,地址SWAP后,无法...

The implementation mimics what has already implemented for H5. This same problem has already been raised in the past, and exactly this fix has been proposed, but never implemented. See here embassy-rs/stm32-data#464 (comment) At the moment the bank swap is not supported...
STM32H7的两个Flash BANK是独立的,读写和擦除互补影响,256bit带宽,CPU访问是采用的两个64bit AXI总线。 70.2.2 内部Flash框架 关于内部Flash的框架,了解以下几个知识点即可: 256bit为单位,即32字节,并且每个单位配10bit的ECC校验位。正是这个原因要求大家对Flash进行编程时,必须以32字节为单位。
If I perform a bank swap the same behaviour goes but is instead shifted to bank 3 instead of bank 1,namely I crash and lose debugger connection when trying to access flash bank 3 (0x700000-0x7FFFFF). I have also played around trying to reproduce the issue with different binaries and ...
