外挂jffs2一直失败

1. Produce a JFFS2 image on Linux PC
   >sudo apt-get install mtd-tools (这行是什麼,所以我用mkdir iffs2建设资料夹)
   >mkfs.jssf2 -d jffs2/ -o jffs2.img (我从网络下载到mkfs.jssf2用他生成jffs2.img)

2. Produce production ROM image
[Image 5]             (我在mkrom.ini 加入这些生成rom.bin)
Image=jffs2.img
Name=jffs2
Base=0x7F300000
Load=0x7F300000
Active=0
Copy to RAM=0
Execution=0
Compressed=0
File=1
No Footer=1

3. Configure Kernel
File systems --->       (我使用make linux_menuconfig內查看是这样定义没错)
         Journalling Flash File System v2 (JFFS2) support
         JFFS2 ZLIB compression support (recommended)

4. JFFS2 partition address
   \W90P710-uClinux\uClinux-dist\linux-2.4.x\drivers\mtd\maps\w90n7xx_map.c
   {
   name: "data (1024k)",
   size: 0x100000,
   offset: 0
   },
{
   /*if jffs2 can run on this partition the size can not less than 6 sectors*/ (我沒修改原先就這樣)
   name: "user (384k)",
   size: 0x60000,
   offset: 0x00300000 //offset
}

5. Mount the partition on the target board

/> mount -t jffs2 /dev/mtdblock1 /flash (最後出現錯誤)
mount failed: Unknown error 19
/>
