2) КФС постоянно затирается, при перезагрузке, на дефолтную. КФС записанна во флэш. При установке использовал эту:uramdisk_bb1.8.2.gz Возможно ли как-то сохранять изменения?

Это и называется _ram_ disk

> Возможно ли как-то сохранять изменения?

Да, использовать как корень файловую систему jffs2 на /dev/mtdblock2

[QwerTech]

спасибо попробую

[QwerTech]

Попытался использовать jffs2. Делал по аналогии

Код: [Выделить]

setenv jffs_file rootfs.jffs2
setenv kern_file uImage
setenv kern_fladdr 60080000
setenv jffs_fladdr 60300000
setenv jffs_size 3d00000
setenv fileaddr 0
setenv serverip 10.42.42.1
setenv kern_flash 'tftpboot ${fileaddr} ${kern_file}; erase ${kern_fladdr} +${filesize}; cp.b ${fileaddr} ${kern_fladdr} ${filesize}'
setenv jffs_flash 'tftpboot ${fileaddr} ${jffs_file}; erase ${jffs_fladdr} +${jffs_size}; cp.b ${fileaddr} ${jffs_fladdr} ${filesize}'
setenv bootcmd 'bootm ${kern_fladdr}'
setenv reflash 'echo Re-flashing...; protect off all; run kern_flash; run jffs_flash; imls; echo Re-flash done'
setenv bootargs 'console=ttyAM0,57600n8 root=/dev/mtdblock2 rootfstype=jffs2'


в итоге

VFS: Unable to mount root fs via NFS, trying floppy.
No filesystem could mount root, tried:  jffs2
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)Подскажите, а надо ли предварительно создавать раздел с файловой системой jffs2? Или она там уже есть?

И еще не много не ясна фраза:

Значение переменной jffs_fladdr для Тион-Про2 3d00000, для Тион/Тион-Про 500000

Но ведь 3d00000 не лежит во flash? Или я совсем запутался?

[asv]

В моём сообщении http://www.zao-zeo.ru/forum/index.php?topic=214.msg1046#msg1046
речь идёт о jffs_size, как видно по приведённому коду. Сообщение я исправил.

[asv]

> Подскажите, а надо ли предварительно создавать раздел с файловой системой jffs2? Или она там уже есть?

Flash в Linux уже разделена на три раздела, файловую систему на третьем вы создадите записав образ ФС по адресу 60300000, предварительно стерев весь третий раздел размера jffs_size. Значения адресов, размеров, размеров стираемых блоков можно узнать в U-Boot по командам flinfo и mtdparts.

[QwerTech]

Не подскажете, где можно узнать как задавать соответствующий блок стирания? Или это необходимо для создания сборки КФС?

Вот что выдает mtdparts:

Код: [Выделить]

$ mtdparts

device nor0 <flash>, # parts = 3
 #: name                        size            offset          mask_flags
 0: u-boot              0x00080000      0x00000000      1
 1: kernel              0x00280000      0x00080000      1
 2: fs                  0x03d00000      0x00300000      0

active partition: nor0,2 - (fs) 0x03d00000 @ 0x00300000

defaults:
mtdids  : nor0=flash
mtdparts: mtdparts=flash:512k(u-boot)ro,2560k(kernel)ro,-(fs)Вот так задан bootargs:
bootargs 'console=ttyAM0,57600n8 root=/dev/mtdblock2 rootfstype=jffs2 video=ep93xxfb:vout=1,vmode=16'

Соответствует ли второму разделу(fs) root=/dev/mtdblock2 ?

Если не затруднит, не подскажете как еще можно узнать почему не монтируется КФС?

[asv]

> задавать соответствующий блок стирания?

Указывается при создании образа jffs2 при выполнении mkfs.jffs2

> Соответствует ли второму разделу(fs) root=/dev/mtdblock2 ?

Да

> Если не затруднит, не подскажете как еще можно узнать почему не монтируется КФС?

В U-Boot выполните ls, показывает список файлов?
