I’m trying to work a Linaro Ubuntu desktop on a zynq 7000 through an SD Card. After making the two partitions on the SD card and inserting in the FPGA, I get this message on my host PC (linked to the card through a serial port using UART) :

EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) on device 179:2.

Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

The error tells you that the system cannot find init.
The system could not mount your drive hence the error devtmpfs: error mounting -2
Your files might be corrupted or your SD card is not recognized and connected properly.
You might need take a look at your file system. Make sure that all the folders like /bin /boot /dev /etc /home /install /lib ... are all in / . Remove the extra directory if you have it.

You may need to check the location of init in your filesystem as the error seems to point out that init is not locatable.
Further, the devtmpfs: error mounting -2 seems to convey that the devtmpfs mounting point is not present in the root partition.
Check whether whether rootfs is available or not in the root partition of card

А подключенный к VGA монитор ничего не отображает. Может ли кто-нибудь помочь мне понять причину этой проблемы?

Лучший ответ
Ошибка сообщает вам, что система не может найти init.
Системе не удалось смонтировать диск, поэтому возникает ошибка devtmpfs: error mounting -2
Ваши файлы могут быть повреждены или ваша SD-карта не распознается и не подключается должным образом.
Возможно, вам потребуется взглянуть на свою файловую систему. Убедитесь, что все папки, такие как /bin /boot /dev /etc /home /install /lib ..., все в /. Удалите лишний каталог, если он у вас есть.

Возможно, вам потребуется проверить расположение init в вашей файловой системе, поскольку ошибка указывает на то, что init не может быть обнаружен.
Кроме того, devtmpfs: error mounting -2, похоже, указывает на то, что точка монтирования devtmpfs отсутствует в корневом разделе.
Проверить, доступен ли rootfs в корневом разделе карты

I’m trying to run a recent enough kernel (4.9) on an Inforce 6540 board, a single-board computer with a Qualcomm Snapdragon 805 (Also called APQ8084, a SoC with four Krait 450 Cores, ARMv7-A).
The system starts, and print a trace on the serial interface, but can’t run init.
Starting init: /sbin/init exists but couldn’t execute it (error -117)
The error code may also be -2, in both case it makes no sense to me.
I also note that devtmpfs failed to mount. The ext4 rootfs is told to be mounted successfully.
Usual explanations are:
- The kernel lacks devtmpfs support. I checked my config, devtmpfs is enabled.
- The filesystem is corrupted. I replaced the kernel (and the devicetree) with the old custom 3.10 kernel originally used by the board, the old kernel manage to launch init (a link to systemd, which stops a little after, as we may expect from a userland built for a 4.9 kernel running on a 3.10 one). (the kernel and the devicetree are not on the rootfs partition, and are loaded by u-boot).
What may explain that init can’t be run ?
Hereafter follows the whole boot trace from the kernel.

What am I missing so the boot process fails with these two errors?
Я собрал вставлено MLO и uboot.img файл в MMC — карты и теперь пытается загрузить «корневой файловой системы «.there проблема в loading.Following являются линии в конце LOG..:

Паника в ядре — не синхронизация: нет init. Попробуйте передать init = параметр в ядро. См. Руководство по Linux/init.txt для руководства.

Является ли проблема связана с rootfs или uboot или переменными окружения?
