How to use MTD util: nandwrite

How to use MTD util: nandwrite

[Wanghao.Yu]

Hi,
I met a problem when I used nandwrite to copy file to NandFlash.
The command I used is as follows.
#nandwrite /tmp/hello /dev/mtd0 (copy file named hello to /dev/mtd0)
The error message is 
MEMGETINFO: Inappropriate ioctl for device.
Before using nandwrite, I have already used "flash_eraseall -j /dev/mtd0" to erase the NandFlash.
I don't know where the problem is.
Could anyone help me?

Best Regards,

I last tried this a year ago and it worked. But I wouldn't be surprized
if someone broke the utility. So I'd suggest you to debug
nandwrite/kernel.

Hello Yu Wanghao!

   It's seemed that you made a low level mistake.

   Plz read the the nandwrite's usage and code carefully:  "Usage:
nandwrite [OPTION] MTD_DEVICE INPUTFILE" ,  but your command is :
"nandwrite /tmp/hello /dev/mtd0 ."

   RTFM !
