Hi,
Once after the kernel and file system are up, I can see the mtd partitions under /proc/mtd/ .
But, mtd partitions are not listed when I run the df command or mount command.
Following mount command also fails.
#mount -t jffs2 /dev/mtdblock2 /mnt/testdir
Regards,
Prabhu
Once after the kernel and file system are up, I can see the mtd partitions under /proc/mtd/
Can you provide the output of `ls -al /dev/mtd*`?
Also, can you pls attach a complete Kernel log.
Following mount command also fails.
#mount -t jffs2 /dev/mtdblock2 /mnt/testdir
How does it fail (log)?
Regards, Andreas
Output for
mount -t jffs2 /dev/mtdblock2 /mnt/test
tried other types of file system.
That is also failed with the following output.
output for
#ls /dev/mtd*
output for
#mount
Output for
#df
mkfs commands available on the target.
Regards,
Prabhu
Dmesg log is also attached. Taken just after the kernel and file system are up.

Thanks for the additional info, will review first thing next week.

Hi Prabhu,
so reviewing what you sent I see evidence in several places that the Kernel is aware of the following (and only those) flash regions/partitions:
[ 0.208027] 0x000000000000-0x000000080000 : "SBL_STAGE1"[ 0.209140] 0x000000080000-0x000000100000 : "SBL_STAGE2"[ 0.210097] 0x000000100000-0x000000200000 : "DM_APP"
...which get exposed to the system through /dev/mtd*{0,1,2}
All these are raw partitions, containing straight binary firmware images. There is no filesystem associated with those partitions, hence mounting those won't work.
If you want to access these raw-data containing partitions you should use the character device for this. For example, to see the contents of the partition that holds "SBL_STAGE1" you would do this (on my system it's all 0xff - erased)
root@am62pxx-evm:~# hexdump -C /dev/mtd0 | head 00000000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00080000
I suppose you are using an SBL-based bootflow, using the bootloader from the MCU+ SDK. If you want to have a filesystem on your flash you need to edit the device tree file to define additional partition(s), which you can then format with a specific filesystem (using `mkfs.xxxx`), and then you can mount them.
