Posted on September 08, 2014 at 05:01Hi,
My project with STM32F407 requires save an 100 element array into internal flash(do not use backup SRAM). But first, I have to erase the location sector (128KB), and it take to much time (about 800ms). Someone can confirm me that: ''internal flash programing must erase all bytes in sector or only the bytes save the array?'' and show me the solutions when i need reduce saving time.
Thanks in advance.
Best regards,
Nhan
