As most of them are occupied by the application, I can give FatFs at most only 1 KBytes. SPI flashes usually have a very large erase unit (e.g W25Q64 is 4 Kbytes size). That's the minimum size that FatFs can operate on the SPI flash. So how do I solve this problem?

WebJul 23, 2024 · No defragmentation is required to fit large files in, because it is all sector based and there is a chain for each file maintaining which sectors are occupied by it. So the file does not need to be contiguous etc. 2. Erasing Sectors: At the moment when FatFS asks me to write a sector, I always erase it first (just to get things working). Web例如对STM32内部Ox8000 0000地址写入一个数据,FMC控制器会控制对应的管脚输出一个满足Nand Flash的时序,发送一个数据到Nand Flash设备。 同理读取读取内部的寄存器,也会生成一个时序从Nand Flash读取一个数据。
