fail to mount ( rw option, type 1DX... )

[openclosed]

I purchased the i.MX6QP SABRE Board.
Here is an SD card with Android porting.
And I want to connect murata type 1dx wifi module to i.MX6qp saber.
The murata guide document says to copy the Type 1DX firmware to the "/etc/firmware/bcm" folder.
However, the "/etc/firmware/bcm" folder is "read only" and cannot be copied.

So I did the mount command.
sabresd_6dq: / # mount -o rw, remount / system
However, with the following error, "rw" was not an option.

Buffer I / O error on dev dm-0, logical block 0, lost sync page write
EXT4-fs (dm-0): re-mounted. Opts: data = ordered
sabresd_6dq: / #
sabresd_6dq: / # Buffer I / O error on dev dm-0, logical block 360954, lost sync page write
JBD2: Error -5 detected when updating journal superblock for dm-0-8.
Aborting journal on device dm-0-8.
Buffer I / O error on dev dm-0, logical block 360954, lost sync page write
JBD2: Error -5 detected when updating journal superblock for dm-0-8.

Why does this happen?
 Is there any way to copy Type 1DX firmware to "/etc/firmware/bcm" folder?

Hi. igorpadykov

Thank you very much for answering my question.
I have seen Linux, Android guide documentation.
Since copying files to / system folder is a phenomenon of i.mx
You may be able to answer here.
Do you know why there is a problem mounting?
