Trouble getting MTD to run -- permission denied messages

[Subodh Nijsure]

I have defined my NOR flash layout as follows I am able to see the
contents of the flash when I do

dd=/dev/mtdblock1 of=/tmp/myflash

However I created a jffs2 image on my workstation and tried to "burn"
it to flash by executing following command  and I see messages "This
doesn't seem to be valid MTD flash device.

# ./flashcp /initrd.jffs2 /dev/mtdblock1
mtdblock_open
ok
This doesn't seem to be a valid MTD flash device!
mtdblock_release
ok

Also mtdinfo -a display following message

# /mtd/mtdinfo -a
Count of MTD devices:           3
MTD_open
libmtd: error!: cannot open "/dev/mtd0"
        error 13 (Permission denied)
mtdinfo: error!: libmtd failed get MTD device 0 information
         error 13 (Permission denied)

I must have missed some basic step in getting things setup for NOR
flash, would appreciate a nudge in right direction...



static struct mtd_partition my_flash_partitions[] = {
        {
                .name = "Linux",
                .offset = RW_PART2_OF,
                .size = RW_PART2_SZ,
                .mask_flags = MTD_WRITEABLE
        },
        {
                .name = "ramdisk",
                .offset = RW_PART3_OF,
                .size = RW_PART3_SZ,
                .mask_flags = MTD_WRITEABLE
        },
};


struct map_info my_flash_map = {
        .name = "My device",
        .size = WINDOW_SIZE,
        .bankwidth = 2,
        .phys = WINDOW_ADDR,
};


When I boot my board I see following messages :
