启动Linux系统时，看到类似下面的启动信息则说明SPI Flash被成功检测到了:
m25p80 spi0.0: mx25l12805d (16384 Kbytes) 1 ofpart partitions found on MTD device spi0.0 Creating 1 MTD partitions on "spi0.0": 0x000000000000-0x000001000000 : "spi-flash"
SPI Flash在Linux系统下的使用方法如下:
# cat /sys/class/mtd/mtd0/size # 以byte为单位 # cat /sys/class/block/mtdblock0/size # 以sector(512 byte)为单位 # apt-get install mtd-utils # flash_eraseall -j /dev/mtd0 # 格式成jffs2的格式 # mount -t jffs2 /dev/mtdblock0 /mnt # mkfs.ext4 /dev/mtdblock0 # 格式化为ext4 # mount -t ext4 /dev/mtdblock0 /mnt
