nandwrite 写 yaffs2 文件系统问题求教

821586284 2016-09-21 05:58:56

操作步骤如下：
/mnt/update # flash_eraseall /dev/mtd2
Erasing 128 Kibyte @ 2800000 - 100% complete.
/mnt/update # nandwrite --help
BusyBox v1.22.1 (2016-08-27 10:50:25 CST) multi-call binary.

Usage: nandwrite [-p] [-s ADDR] MTD_DEVICE [FILE]

Write to MTD_DEVICE

-p Pad to page size
-s ADDR Start address

/mnt/update # nandwrite -p -s 0x20000 /dev/mtd2 970fs48.yaffs2

重启之后就出现这样的问题。我的nand flash 一个 block 大小是 0x20000 bytes, 这是什么原因，求帮助
