根文件系统是cramfs，把mtd一个分区挂载为yaffs2格式的，挂载点是根文件系统上的一个目录home，用mount -t yaffs2 /dev/mtdblock3 /mnt挂载成功，建立文件或拷贝文件出现下列错误:
**>> yaffs chunk 12352 was not erased
**>> yaffs chunk 12353 was not erased
**>> yaffs chunk 12354 was not erased
**>> yaffs chunk 12355 was not erased
**>> yaffs chunk 12356 was not erased
**>> yaffs chunk 12357 was not erased
**>> yaffs chunk 12358 was not erased
**>> yaffs chunk 12359 was not erased
**>> yaffs chunk 12360 was not erased
**>> yaffs chunk 12361 was not erased
**>> yaffs chunk 12362 was not erased
**>> yaffs chunk 12363 was not erased
**>> yaffs chunk 12364 was not erased
再次写文件时，会出现Cannot allocate memory
有哪位大侠遇到过,请指教啊
