Does it make a difference if you explicitly specify the file system type,
by adding "-t ext3"?
I have tried to specify the system type by adding "-t ext3" or "-t ext4",
but it has no change anything.
I attached the qspi test logs file. Please see it.
"renesas_spi qspi.0: master is unqueued, this is deprecated"
So this is indeed a very old version of the rspi driver.
Which 3.10.31-ltsi are you using? The one from renesas-backports?
The source code is link below:
http://ltsi.linuxfoundation.org/sites/ltsi/files/patch-3.10.31-ltsi.gz
This qspi is added on rspi driver together that i am using. I think that
It was back-ported from a upstream version. I think this message does
not causing of the problem.
I have enabled ext2,3,4 file systems when configuring the kernel.
and I saw that the qspi driver code is same with upstream version code
that
be good.
maybe the problem related to mtd (m25p80.c) (?)
I attach the logs files when making a spi-flash partition and mount it on
rootfs.
It looks like the file system wasn't written correctly to the device.
Do you see anything suspicious in the kernel log (dmesg)?
No, I don't see anything suspicious in the kernel log. It is normally log
for qspi.
Strange.
Can you check that writing works using some other way, e.g. using dd?
I have checked the writing works using other way (using dd command
directly) as below:
