UBIFS image support? #433
Comments
|
The file size is too large. I am not sure if you must generate the
single large ubifs image or if you can use the rootfs tarball with
following commands.
# burn rootfs
FBK: ucmd source /tmp/mtd.sh; flash_erase /dev/mtd${nandrootfs} 0 0
FBK: ucmd source /tmp/mtd.sh; ubiattach /dev/ubi_ctrl -m ${nandrootfs}
FBK: ucmd source /tmp/mtd.sh; ubimkvol /dev/ubi0 -Nnandrootfs -m
FBK: ucmd source /tmp/mtd.sh; mkdir -p /mnt/mtd
FBK: ucmd source /tmp/mtd.sh; mount -t ubifs ubi0:nandrootfs /mnt/mtd
FBK: acmd export EXTRACT_UNSAFE_SYMLINKS=1; tar -jx -C /mnt/mtd
FBK: ucp _rootfs.tar.bz2 t:-
FBK: sync
FBK: ucmd umount /mnt/mtd

Hi,
I am wondering if there is support to directly transfer the whole ubifs image through uuu.
I build the rootfs by using ubifs for SOC_DEFAULT_IMAGE_FSTYPES in Yocto.
The product is a custom board based on iMX6UL with raw NAND Spansion S34ML04G200BHI (SLC).
I tried something like:
# burn rootfs
FBK: ucmd source /tmp/mtd.sh; flash_erase /dev/mtd${nandrootfs} 0 0
FBK: ucmd mkfifo /tmp/ubifs_pipe
FBK: acmd source /tmp/mtd.sh; ubiformat /dev/mtd${nandrootfs} -f /tmp/ubifs_pipe
FBK: ucp _rootfs t:/tmp/ubifs_pipe
And no surprise it does not work.
So, is there any way to transfer large image into FBK?
Thanks in advance.

Hi thanks for your reply. |

I am not sure if it works, but it is no harm to try
# burn rootfs
FBK: ucmd source /tmp/mtd.sh; flash_erase /dev/mtd${nandrootfs} 0 0
FBK: acmd source /tmp/mtd.sh; ubiformat /dev/mtd${nandrootfs} -f -
FBK: ucp _rootfs t:-

Hi thanks for your reply.
I know tar ball works and I have succeeded on that. And I understand the
tar ball gives us flexibility on strict raw NAND partition.
I am seeking the possibility of new way of packaging whole image, so that
does not break our existing production line too much.

Thanks Allen, It gets stuck at 0%. |

If you boot to the kernel and burn this ubifs image(or a smaller one), does
it work?

Currently not possible. If I boot into a rootfs, I am not able to unmount the ubi partition to run nand format. |
