We have created, following the instruction on wiki-xilinx-linux web page, a system Zybo + embedded linux kernel (I want to remark that we didn't use PetaLinux but we have built all the file with the Xilinx tools).
When we turn on the system everything works fine and this is the output at the boot time:

It is clear that there is an error with the "mounted filesystem":
zynq> EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) on device 179:2.
Trying to move old root to /initrd ... /initrd does not exist. Ignored.
Unmounting old root
Trying to free ramdisk memory ... failed
devtmpfs: error mounting -2
Why does this happen? Why before I can do everything with the system and, suddenly, I have a crash? Yes, the system crashes when I am doing nothing on it and not when I am working with it.
Are there some advice to solve this? to not to have anymore these crashes?
From the Linux Kernel Command line I can see "root=/dev/mmcblk0p2" and also the target is started with initial ramdisk image "uramdisk.image.gz". So the init process or scripts inside ramdisk image should be responsible to mount the real file system from SD i.e. from /dev/mmcblk0p2 and remove the used memory of ramdisk. To narrow down the problem, you need to analyze the steps taken in ramdisk image to mount the real filesystem and make sure you have the proper RFS flashed inside SD in /dev/mmcblk0p2. I can also seen some missing directories to mount the /dev/mmcblk0p1 and /dev/mmcblk0.
++ Mounting filesystem
mount: mounting /dev/mmcblk0p1 on /mnt failed: No such file or directory
mount: mounting /dev/mmcblk0 on /mnt failed: No such file or directory
In simple words, check the init scripts inside the ramdisk image and make sure the RFS is mounted properly.

I am following Bootlin's embedded Linux training which aims to put an embedded Linux system on an Atmel SAMA5D4 Xplained board (theory slides, practical lab instructions) and I am stuck a putting the whole system on the NAND flash.
They ask me to put the DTB, the kernel, the root filesystem and a data filesystem in a UBI image to be written to the flash but I cannot access the UBI partitions once I flashed it (the access fails with error code 22, or -22 in an embedded Linux environment).
Detailed description
(to see my actual questions, go to the end of the question)
In U-Boot, the partitions are defined by mtdparts:
device nand0 <atmel_nand>, # parts = 8
#: name size offset mask_flags
0: bootstrap 0x00040000 0x00000000 1
1: uboot 0x00080000 0x00040000 1
2: env 0x00040000 0x000c0000 1
3: envbackup 0x00040000 0x00100000 1
4: dtb 0x00020000 0x00140000 0

7: datafs 0x01000000 0x01660000 0
active partition: nand0,0 - (bootstrap) 0x00040000 # 0x00000000
defaults:
mtdids :
mtdparts:
With printenv mtdparts, I get:
mtdparts=mtdparts=atmel_nand:256k(bootstrap)ro,512k(uboot)ro,256k(env)ro,256k(envbackup)ro,128k(dtb),5M(kernel),16M(rootfs),16M(datafs)
and printenv mtdids
mtdids=nand0=atmel_nand
The UBI image was created with ubinize and the following configuration:
[dtb]
peb=0x20000
min_io_size=0x800
mode=ubi
image=dtb.img
vol_id=0
vol_size=128KiB
vol_type=static
vol_name=dtb
vol_alignment=1
[kernel]
peb=0x20000
min_io_size=0x800
mode=ubi
image=zImage
vol_id=1
vol_size=5MiB
vol_type=static
vol_name=kernel
vol_alignment=1
[rootfs]
peb=0x20000
min_io_size=0x800
mode=ubi
image=root.img
vol_id=2
vol_size=16MiB
vol_type=static
vol_name=rootfs
vol_alignment=1
[datafs]
peb=0x20000
min_io_size=0x800
mode=ubi
image=files.img
vol_id=3
vol_size=16MiB
vol_type=static
vol_name=datafs
vol_alignment=1
and this command (the sama5-ubinize.cfg is the above configuration)
ubinize -o ubi.img -p 128KiB -m 2KiB sama5-ubinize.cfg
The PEB is indeed 128KB (0x2000) and the page size is 2048B (0x800). I added those parameters based on this answer.
Both UBI partitions have been make with the following commands:
mkfs.ubifs -e 124KiB -c 132 -m 2KiB -r nfsroot/ root.img
mkfs.ubifs -e 124KiB -c 132 -m 2KiB -r nfsroot/www/upload/files data.img
I then write the UBI image to the flash with the following commands (in U-Boot):
nand erase 0x140000 0xfec0000
tftp 0x21000000 ubi.img
nand write.trimffs 0x21000000 0x140000 0x880000
When trying to access the partitions from U-Boot with ubi part rootfs, I get the following error:
ubi0: attaching mtd1
ubi0: scanning is finished
UBI init error 22
For now I am booting Linux from a SD card. The Linux boot arguments are (from printenv bootargs):
bootargs=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait
When booting Linux, I get the following log:

Enter 'help' for a list of built-in commands.
It detects all but one partition, but I cannot access them either. When trying to attach any of them (with ubiattach -m 5 /dev/ubi_ctrl), I get the following error (the error stays the same for all partition numbers):
ubi0: attaching mtd5
ubi0: scanning is finished
ubi0 error: ubi_read_volume_table: the layout volume was not found
ubi0 error: ubi_attach_mtd_dev: failed to attach mtd5, error -22
ubiattach: UBI_IOCATT: Invalid argument
My questions
What exactly goes wrong my setup?
Should there be any preparation for the DTB and the Linux kernel before I put them in the UBI image?
Used tools and versions
U-Boot 2017.09
Linux 4.18
busybox 1.29.3

Thanks for the very well described problem and questions. It's a pleasure to help you in such conditions :)
There are a few things don't seem right, or which at least are not in the spirit of Bootlin's lab.
You don't have the mtdparts settings in the kernel command line. As a consequence, you're working with the default partitions.
You're flashing your UBI image into the 5th MTD partition (from the offset you're using) but are trying to attach UBI to the 6th partition. No surprise that you have UBI attach issues.
When erasing and flashing the UBI images, you should use partition names instead of offsets. This will clarify things and reduce the risks of errors.
You should group the dtb, kernel, rootfs and datafs partitions into a single MTD partition called "ubi", which you will use to flash the UBI image and then to attach UBI. So instead of MTD partitions, you will have 4 UBI volumes, as described by your ubinize configuration file.
This should definitely help. Don't hesitate to come back if you're still facing issues after doing this.
Happy hacking and learning
Michael (from Bootlin)
I raised another thread as a followup
bootlin kernel doesn't boot from UBIFS
hope Michael can review it too

What is very weird is that I have the same version of OpenWRT system with a Linux 2.6.32 and it works well. Do I have additionnal kernel options to configure for linux 3.12.X for making it works with Qemu 2.0.0 ?
Thank you in advanced for your helps and comments.
There may be something wrong with your bin/x86/openwrt-x86-sgc_qemu-rootfs-ext4.img file. Where did you get that file from?
Also, you're specifying a disk device as the root filesystem for the kernel (root=/dev/sda) . This is wrong. You're suppose to specify a partition not a disk device. So you probably meant to say "root=/dev/sda1". It's safer to specify a UUID instead of a partition name (e.g. root=UUID=3552064b-7e4d-4e3a-ae48-943b333267d9 ) in case your root partition isn't actually /dev/sda1.
You can extract the UUID for your virtual root partition by creating loopback devices from your disk image:
losetup -P /dev/loop1 bin/x86/openwrt-x86-sgc_qemu-rootfs-ext4.img.
You should see new devices created called /dev/loop1p1 , /dev/loop1p2 , etc. Your virtual partition /dev/sda1 will be created as /dev/loop1p1, /dev/sda2 will be /dev/loop1p2 etc. You can then determine the UUID using parted or gparted on /dev/loop1
You may also need to specify something like "format=raw" in your qemu command, if the disk image is a raw disk image, or you may need to convert it first to a qcow2 image (qemu-image convert).

I've try boot from SD card on real T4240RDB board, it happen the same error.
Please help me.
Thanks in advance
Because the warning:
WARNING: Host distribution "Ubuntu-16.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.
I have tryed build on Linux Ubuntu 14.04 LTS, but the same error when I boot the image and rootfs.
I'm attempting to get a persistent distribution (Linaro) on an SD card, up and running on the ZedBoard. I built the kernel from the linux-xlnx source, and have run into a number of issues during startup. I've managed to overcome most of the kernel hangs I've been experiencing at bootup, but I'm stuck at "Registering SWP/SWPB emulation handler".
I've noticed an option in the .config file "CONFIG_SWP_EMULATE=y", but even if I comment this out (and I don't know if I should be doing this anyway, to be honest), when I go to rebuild the kernel with "make UIMAGE_LOADADDR=0x8000 uImage", this line just gets re-enabled in the .config file for whatever reason, and the problem persists.
The original configuration was created using "make xilinx_zynq_defconfig". I then used "make menuconfig" to enable earlyprintk and low-level debugging in the kernel hacking menu (displaying the output on UART1). From there, I directly edited the .config file each time the kernel got stuck at some point. The notable changes from the "xilinx_zynq_defconfig" thus far are:
CONFIG_DEBUG_LL=y
CONFIG_DEBUG_ZYNQ_UART1=y
CONFIG_EARLY_PRINTK=y
# CONFIG_SERIAL_XILINX_PS_UART is not set
# CONFIG_RTC_HCTOSYS is not set
CONFIG_ARM_THUMB=y
CONFIG_ARM_THUMBEE=y
Any suggestions on how to overcome this issue would be appreciated. Thank you in advance :)

Registering SWP/SWPB emulation handler
I was provided with a 3.0.35 linux kernel for an arm i.mx6 board that uses the older "board file" format, as well as an older (2013.02) buildroot repo that has been used to generate the proper images and rootfs.
My goal is to use the latest buildroot public repo commit so that in the future it will be easier to keep packages up to date. Currently, I have to manually edit package files (OpenSSL, lighttpd, etc) to make the latest version available via buildroot.
I tried replicating my board configuration within the latest buildroot (post-2016.05). Everything remained more or less the same, except the toolchain had to change to support the newer systemd (Linaro 2013.01 -> CodeBench ARM 2014.05). Results:
Buildroot: build succeeds
U-boot: image works
Kernel: image causes a kernel panic
My questions really are:
Can I use my older kernel with the newer buildroot/toolchain, or is this an incompatibility? Do certain toolchains not support older kernels?
If it is an incompatiblity, is there an easier way to keep my older buildroot's packages up to date?
If both above are not options, is there any sort of tool to help migrate from a board file to device tree? Is it easy to convert to dts, or is this a long project?
EDIT:
Changed to Linaro 2014.09 toolchain. I was previously using systemd 202 as my init system. Since the newer buildroot requires a toolchain built against kernel headers >= 3.10 for systemd, I had to switch my init system to systemv. Here is the crash I'm receiving:

As I stated in a comment, the crash looks very similar to the one in Freescale 3.0.35 kernel crash. If so, the crash happens in memset.S. The top two commits in memset.S in upstream kernel whose SHA1 begins with c2459d3 and 1bd4678, respectively, should solve that issue.
