Здравствуйте!
Есть плата NUC950. Гружу ядро 2.6.35.4 взятого с китайского форума (официального Linux 2.6.35 BSP не нашел). Не грузиться файловая с SD (файловая рабочая проверено на SK-AT91SAM9xe512). В чем может быть проблема?

а строка загрузки ядра доступна для изменений/добавлений?
попробуйте туда добавить
Код
noinitrd init=/bin/sh

или
Код
noinitrd init=/bin/ash

или
Код
noinitrd init=/bin/bash

при удаче выпадете в командную строку..

чтобы проц был чуть пошустрее

я помню, что подключить к МНЮКу рутовую было хлопотным занятием..
- попробуйте вместо rootwait прописать rootdelay=15
- попробуйте в опция ядра включить эмуляцию сопроцессора -
Код
CONFIG_FPE_NWFPE=y

- попробуйте сборку ядра со сменой опции ядра OABI/EABI

Как загрузиться с NAND

вы уверены, что в этом ядре есть нормальная поддержка nand для NUC950?
тогда траектория такая:
- в ядре включаете поддержку нанда, mtd и поддержку ФС во флеше, в файле платы прописываете свой нанд и разбивку на партиции..
далее развилка:
-- формируете образ рутовой в бинарник и заливаете через тулзу по USB
-- грузитесь с любой рутовой (хоть с ramfs) аттачите нанд, форматируете, монтируете и заливаете туда рутовую
далее в строке загрузки ядра прописываете - с какого раздела нанда грузиться и что там за ФС..

описание процесса пилежки нанда на форуме есть..

зы интересно, что в свое время, мы пилили схожий номер ядра, дело заглохло на глючащем USB и полуживом SD/MMC

На любой вопрос есть любой ответ.

То же характерно как для драйвера что шел в комплекте с ядром и взятого с форума
Код
http://starterkit.ru/html/index.php?name=forum&op=view&id=6785&num=23

Вроде Nand распознает:
Код
NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB 3,3 V 8-bit)

Однако настораживает:
Код
Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c0004000

В чем может быть проблема?

Проблема оказалась в кривых драйверах. Сам Nuvoton придерживается странной политики - они не стали делать драйвер MTD для NAND флешки, вместо этого родили SCSI драйвер-прослойку. Тема поднималась:
Код
http://starterkit.ru/html/index.php?name=forum&op=view&id=5168&num=3

Немного покопал по форумам - удалось исправить ошибку в файле nuc900_nand.c. Драйвер вроде заработал. Теперь пытаюсь смонтировать файловую:
Заливаю утилитой Turbo Writer записать ядро, указывая: номер образа - 1, тип - "Execute", Image execute address - 0x8000, Image start block - 1
записать корневую ФС, указывая: номер образа - 2, тип - "RomFS", Image execute address - 0xa00000, Image start block - 20
В файле платы следующие партиции:
Код
static const struct mtd_partition partitions[] = {
{
.name = "Nand-boot",
.offset = 0,
.size = 128 * 1024
},
{
.name = "Kernel",
.offset = 128 * 1024,
.size = 31*128 * 1024
},
{
.name = "Rootfs",
.offset = 32*128 * 1024,
.size = MTDPART_SIZ_FULL
}
};

Файловая так и не грузиться:
Код

попробуйте зайти с другого угла - поддержка сети вроде должна быть живой..
- соберите ядро и маленькую рутовую в единый файл, в составе рутовой основной упор на утилиты работы с флешом
- соберите ядро с поддержкой NFS и держите рутовую на сетке (хоть в той же виртуалке)
цель - получить загруженную систему и консоль, далее утилитами можно пилить нанд..

На любой вопрос есть любой ответ.
