Re: [Yaffs] How can I mount yaffs2 on ubuntu 12.04

Thanks again.


It sounds has been mounted correctly, but about the second way to check, where I have to create my files to see this changes. Is there any special path for this? (I create a folder contains some files on desktop but, it did not change.)

After that is there anyway for changing and improving the code? for example how I can change something in the source code of yaffs2?

I have to mount it again after change again? or I can change it without mounting after that?

There are a few ways to check everything is there:

1) cat /proc/filesystems
That lists the file systems available. You should see yaffs2 in the list.
Without yaffs2 in the list, mount -t yaffs2 ... will not work anyway.

2) cat /proc/yaffs
This will show info on the currently mounted yaffs partitions. You should see
things change if you create files etc.

3) dmesg
This shows kernel messages. There should be some yaffs messages. You can
control yaffs tracing by using the yaffs tracing mechanism.

That sounds correct.

That only tracks certain file systems. It does not track all file systems.
