Добрый день!!! столкнулся вот с такой проблемой.. Купил плату SK-MAT91SAM9XE512 c камнем SAM9XE512. Закинули all.bin (который был на диске) в датафлеш и Bootstrup в flash. Linux грузится и все работает, теперь стало актуально загружать файловую систему с MMC карточки, все сделал по этой инструкции, http://code.google.com/p/sim1/wiki/RootBoot но файловая системы так и не монтируется (хотя карточка при загруженом Линуксе монтируется).
Help please.........

R<0>Kernel panic - not syncing: Fatal exception in interrupt

давненько я таких длинных логов не видел.. аж в глазах рябит :-/

Код

Loading: *checksum bad
checksum bad

вот это смущает.. а попыток загрузки надеюсь была не одна?

Код

U-Boot> setenv bootargs root=/dex v/nfs ip=192.168.0.136 nfsroot=192.168.02 .2:/home/vitaly/felabs/linux/modules/nfsroot

это относится к загрузки рутовой с NFS

Код

Kernel command line: root=/dev/nfs ip=192.168.0.136 nfsroot=192.168.0.2:/home/vitaly/felabs/linux/modules/nfsroot

и это тоже
у буржуя с вашей ссылки слегка не так:

Код

SIM.ONE> set bootargs console=ttyAM0 root=/dev/mmcblk0p1 rootwait

ключевое для накопителя SD/MMC root=/dev/mmcblk0p1 (или 2,3 и т.д. если разделов на флешке не один)

Да, последний скрин сделаный при попытке закрузки по tftp...
как один из вариантов при безнадежном монтировании файловой системы с СД карточки....согласно http://code.google.com/p/sim1/wiki/RootBoot,
Но при долгом ковырянии, и подправлении booarges, монтирование c SD начиналось но в результате все равно .... (как и анололгично по tftp)
......
R<0>Kernel panic - not syncing: Fatal exception in interrupt

очень все сумбурно и неотчетливо
допустим ваше ядро понимает переопределение параметров при загрузке, допустим корневую скопировали и развернули правильно
попробуйте в командную строку для ядра добавить rootwait или rootdelay=12
первая заставляет ядро ждать готовности накопителя, вторая (в случае цифры 12) ждет 12 секунд и пробует загрузиться с указанного накопителя..

когда у меня на плате стояло 32МБ, то я грузил с такими параметрами ядра
root=/dev/mmcblk0p1 rw mem=32M console=ttyS0,115200 rootwait

Вот мои шаги..
1. Ставлю во Flash - dataflash_sk_mat91sam9xe512.bin
2. Записываю в Dataflash (CS0) - all.bin
3. По ссылке http://code.google.com/p/sim1/wiki/RootBoot создаю файловую система на СД карточке
4. Вставляю СД-ку в плату, запускаю, торможу на загрузке U-boot и прописываю такие параметры
bootargs=console=ttyAM0,115200 root=/dev/mmcblk0p2 rw rootfstype=ext2 rootwait
в результате команды printenv получаю следущие:


bootcmd=run boot_df

bootdelay=2

baudrate=115200

tftp_update=tftpboot 20400000 zlinux; cp.b 20400000 c0038000 3e7fff; boot

(На /dev/mmcblk0p1 просто пустой раздел, файловая система лижит в /dev/mmcblk0p2 )
но я так понимаю что это просто файловая система розвернулась в оперативке, а не ка основная файловая всей системы...

Еще раз зашел в настройки U-boot (перед загрузкой ядра) и в параметрах добавил:
set bootargs rootfstype=ext2


после запуска системы командой BOOT вроде как картина поменялась и по моему мнению че-то начилось монтироваться:

R<0>Kernel panic - not syncing: Fatal exception in interrupt

R

Но все закончилось неудачей (как и с моим ранешним вариантом загрузки по tftp)(((((((( R<0>Kernel panic - not syncing: Fatal exception in interrupt

хм.. как я понял проблема загрузки с накопителя SD отпала? и что помогло?
смущает вот это сообщение:

Код

mmcblk0: p2 size 3823470 limited to end of disk

лень смотреть - какой размер архива из вышеприведенной ссылке? и в какой объем он развернулся на mmcblk0p2?
и заодно посмотреть, что делает команда:

Код

mkfs.ext2 -b 1024 -m 0 /dev/sdb1

может сначала пойти по простейшему пути - создать на SD одну партицию, форматнуть ее mkfs.ext2 /dev/sdb1, развернуть рутовую. а уж потом пилить на разделы..

нижайшая просьба - выкладывайте логи по существу, мозоль натер скроллировать..

в кору выпало "патамучто":

Код

Kernel command line: rootfstype=ext2

сплохело кернелу из-за отсутствия параметров

Hint Находясь под управлением Uboot после setenv иногда полезно писать saveenv, тем самым запоминая переменные окружения юбут во области флеша..
