AM29LV065D FLASH read, erase, program?

Hi all,

1. create these dev files in ROOTFS project in IDE:

@mtd3,c,90,3

@mtdblock,b,31,0

@mtdblock,b,31,1

@mtdblock,b,31,2

@mtdblock,b,31,4

build,upload ROOTFS

2. config MTD, MTD_CHAR

build kernel

3. download netflash from uClinux-dist-2005...tar.bz2

compile it, copy to NFS share dir.

4. after uClinux boot up, I test netflash# netflash -bfkn -r /dev/mtd3 192.168.168.0 testfile

error: open("/dev/mtd3") permission denied

Any suggestion , please?

BTY, flash is AM29LV128 (16MB). My Altera maps is:

Creating 5 MTD partitions on "Altera NDK flash (AMD)":

0x00200000-0x00c00000 : "romfs/root"

0x00000000-0x00200000 : "loader/kernel"

0x00c00000-0x00e00000 : "RW zone/jffs2"

0x00e00000-0x00f00000 : "User configuration"

0x00f00000-0x01000000 : "safe configuration"

I'd like to test ACCESS mtdblock3(mtd3?).
