Hi all,
I am comfused about choosing the sector size in wear levelling example.
I want to use near about 250kb of flash for file system so I have to use sector size 512kb because 4096kb sector size rquires minimum 512kb of flash for file system.
but I actually very confused that what is the difference in this sector sizes(CONFIG_WL_SECTOR_SIZE 512kb & 4096kb)?

Re: Wear Levelling library sector size
Yes. ESP32 SPI Flash sector size is 4096 Bytes only. So, You need to erase minimum 4096 bytes to write data into particular section.burkulesomesh43 wrote: ↑Sat Sep 01, 2018 4:22 pmHi all,
