Unable to access NANDrive Data

amitmodi010 — Wed, 18 Aug 2021 05:41:42 GMT

Hello,

I have a custom board. and Board has

1. TQM5200 Module (it has MPC5200 processor)

2. Mother Board having an FPGA

There is one flash memory on TQM5200 of 64 MB, and one NANDrive of 1GB on the motherboard which is controlled by MPC5200.

My problem is: I am trying to read the data of NANDrive(available on Motherboard) and trying to mount. I have tried some methods to mount but I couldn't.

but after typing dmesg on the serial console it shows the NANDrive.

IDE: found hda hard disk 1 GB NANDrive : ND B642J: 0000000000R1813B

IDE: found hda1

some commands I have tried to mount and the output of those command are shown

$ mount -v /dev/hda /mnt/data
mount: /dev/hda on /mnt/data: Device or address doesn't exist
$ ffsck -vf /dev/hda
superblock damaged, root inode number is 0
number of inodes is 0, number of blocks is 0
superblock hopelessly damaged (no file system?)
(aborting)

The MPC5200 does not support NAND Flash. It supports NOR Flash and HDD ATA.

See the MPC5200B User's Manual:

Perhaps NAND drive on your board is connected to MPC5200 ATA.

Thank you @Pavel for Response,

yes NAND drive( GLS85LD1001T / GLS85LD512 Industrial Grade PATA NANDrive)

is interfaced with ATA controller on the MPC5200.

It looks like that there is no file system on your device /dev/hda.

Try to use the following command:

mount -v /dev/hda1 /mnt

@Pavel I have tried this command also But it didn't work. Is there any other way so that i can access the drive.

one more question How can I know that drive is password protected or not or any other type of security issue.

Create new folder. Check permission. Enable reading/writing for this new folder.

What message happens if /dev/hda1 is mounted to this new folder?
