Manual stm32f4 smallest single erase space for 16 k, I want to write 2 k a brush 2 k, can you change the underlying program

CodePudding user response:

Not, generally need to operate according to the available RAM size, 16 k first data into RAM, if enough RAM, then wipe, then the modified data is written to, if not enough RAM, or 16 k do not use full, or use a multiple sectors for caching, of course the latter will affect the life

CodePudding user response:

Only by the page size to erase, write several times can

CodePudding user response:

After a brush is 16 k brush to write, wants to keep the original array will have a large enough data, read after the deposit, the new data assembly into the array, then write, if have how many bytes can be erased every time want to write
