Creating and use jffs2 partition on MicroZed ZC702x

[sconvertini]

Dear all,

I'm using the MicroZed board mounting the ZC702x.

I'm trying to create a further partition in the flash memory.

To do this I modified the device tree as follow:

ps7_qspi_0: ps7-qspi@e000d000 {
			bus-num = <0>;
			compatible = "xlnx,ps7-qspi-1.00.a";
			interrupt-parent = <&ps7_scugic_0>;
			interrupts = < 0 19 4 >;
			is-dual = <0>;
			num-chip-select = <1>;
			reg = < 0xe000d000 0x1000 >;
			speed-hz = <200000000>;
			xlnx,fb-clk = <0x1>;
			xlnx,qspi-clk-freq-hz = <0xbebc200>;
			xlnx,qspi-mode = <0x0>;
			#address-cells = <1>;
			#size-cells = <0>;
			flash@0 {
				compatible = "n25q128";
				reg = <0x0>;
				spi-max-frequency = <50000000>;
				#address-cells = <1>;
				#size-cells = <1>;
				partition@qspi-fsbl-uboot {
					label = "qspi-fsbl-uboot";
					reg = <0x0 0x100000>;
				};
				partition@qspi-linux {
					label = "qspi-linux";
					reg = <0x100000 0x500000>;
				};
				partition@qspi-device-tree {
					label = "qspi-device-tree";
					reg = <0x600000 0x20000>;
				};
				partition@qspi-rootfs {
					label = "qspi-rootfs";
					reg = <0x620000 0x590000>;
				};
				partition@qspi-data {
					label = "qspi-data";
					reg = <0xBB0000 0x50000>;
				};
				partition@qspi-bitstream {
					label = "qspi-bitstream";
					reg = <0xC00000 0x400000>;
				};
			};
		} ;

I added a partition named qspi-data of 320kB to handle some files I need during the normal execution.

I try to format the partition as a jffs2 type as follow:

zynq> flash_eraseall -j /dev/mtd4
Erasing 64 Kibyte @ 50000 - 100% complete.Cleanmarker written at 40000.

and it seems to work well.

Then I created a new folder to mount the new partition as follow

zynq> mkdir /tmp/data
zynq> mount -t jffs2 mtd4 /tmp/data
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00040000: 0x19ff instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00040004: 0x000c instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00040008: 0xb0b1 instead

And I get this error. Anyway the partition is mounted and it seems to work. But if I create some file in the mounted partition as follow:

zynq> cd /tmp/data
zynq> touch file1.txt file2.txt

If I unmount and re-mount the partition, I get the following errors

zynq> umount /tmp/data
zynq> mount -t jffs2 mtd4 /tmp/data
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00040000: 0x19ff instead

jffs2: warning: (683) jffs2_do_read_inode_internal: no data nodes found for ino #3
jffs2: Returned error for crccheck of ino #3. Expect badness...

I also tried to create a jffs2 image and write it into the /dev/mtd4 partition, as follow:

zynq> mkfs.jffs2 --pad --no-cleanmarkers -d /tmp/data -o rootfs.jffs2
zynq> nandwrite -p /dev/mtd4 rootfs.jffs2
Writing at 0x00000000
Writing at 0x00010000

And this time, if I unmount and re-mount the mtd4, it seems it works well, but if I restart the board, make a new directory /tmp/data I get the following:

zynq> mkdir /tmp/data
zynq> mount -t jffs2 mtd4 /tmp/data

Any suggestions?

Thank to all for any help!

Hi @sconvertini,

Not sure but you should try with mtdblock instead of mtd:

#clean QSPI
#
flash_eraseall -j /dev/mtd4

#create a directory
#
mkdir /tmp/data

mount -t jffs2 /dev/mtdblock4 /tmp/data

cd /tmp/data
touch file1.txt /tmp/data/file2.txt

echo "this is a test" > file1.txt
echo "this is a test" > /tmp/data/file2.txt

# re-mount
#
umount  /tmp/data
mount -t jffs2 /dev/mtdblock4 /tmp/data

# copy and compare files
#
cp /tmp/data/file2.txt .

dif file1.txt file.txt

Cheers,

Trigger

[sconvertini]

Hi,

thank you for you answer.

I cannot unmount /tmp/data. I goot this message

umount: can't unmount /var/volatile/tmp/data: Device or resource busy

even if a execut the sync command, the directory is busy.

Please, could you explain the last two rows command?

cp /tmp/data/file2.txt .
dif file1.txt file.txt

 Thank you

Hi @sconvertini,

Try to mount in an other folder /mnt :

umount: can't unmount /var/volatile/tmp/data: Device or resource busy

#clean QSPI
#
flash_eraseall -j /dev/mtd4

#create a directory
#
mkdir /tmp/data

mount -t jffs2 /dev/mtdblock4 /mnt/qspi

cd /mnt/qspi
touch file1.txt /mnt/qspi/file2.txt

echo "this is a test" > file1.txt
echo "this is a test" > /mnt/qspi/file2.txt

# re-mount
#
umount  /mnt/qspi
mount -t jffs2 /dev/mtdblock4 /mnt/qspi

# copy and compare files
#
cp /mnt/qspi/file2.txt .

diff file1.txt file.txt


Diff is used to compare files.

Cheers,

Dear Trigger,

I can mount and unmount jffs2 partition.

The problem is after rebboting the system.

If I attempt to mount the mtd4 partition in /tmp/data I get the following errors

zynq> mount -t jffs2 /dev/mtdblock4 /tmp/data
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00040000: 0x19ff instead

jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00040008: 0xb0b1 instead

Bye

HI @sconvertini,

Maybe you should take a look to CRC methodology and erase_block size

Cheers,

Trigger

[gudishak]

Hi @sconvertini,

Have you tried with Erase block size 8K? Also make sure that you have a valid rootfs in qspi-rootfs partition.

Can you share complete boot log?

Hi,

what is the complete command to erase the partition with a block size of 8k?

I usually use flash_eraseall.

Thank you
