Попала в мои руки плата аргуссофта AS-9260 (аналог атмелевской at91sam9260ek)
Пытаюсь разобраться с тем как там все работает. Из-за того, что исходников u-boot и linux в комплекте нет, тока бинарники решил начать с того что бы собрать свои версии u-boot и linux.
с первым проблем не возникло, u-boot-2009.01 вроде бы работает без проблем. скомпилирована для arm-elf-gcc.
а вот linux никак не дается.
Перепробовал кучу тулчейнов, несколько версий ядра - компилируется, но при загрузке выдает вот такой лог.

Конфигурацию линукса брал из arch/arm/configs/at91sam9260ek_defconfig
т.к. в логе исходной версии линукса в на месте ошибки идут строчки

то насколько я понял в этом месте должная ити инициализация spi - пробовал компилировать вот с такими строчками
CODE
#
# SPI support
#
CONFIG_SPI=y
CONFIG_SPI_MASTER=y
# CONFIG_W1 is not set
# CONFIG_POWER_SUPPLY is not set
# CONFIG_HWMON is not set
CONFIG_WATCHDOG=y
CONFIG_WATCHDOG_NOWAYOUT=y
# SPI support

CONFIG_SPI=y
CONFIG_SPI_MASTER=y
# CONFIG_W1 is not set
# CONFIG_POWER_SUPPLY is not set
# CONFIG_HWMON is not set
CONFIG_WATCHDOG=y
CONFIG_WATCHDOG_NOWAYOUT=y
результат абсолютно тот же.
Прошу сильно не ругаться, если ошибка на поверхности лежит, и тыкнуть носом куда надо)
