Правка файла борды, при каких условиях Опции

[TigerSHARC]

Работаю с платой lcdk omap-l138. использую SDK от TI.
Недавно задумался: что если я захочу в конечном устройстве поменять размер SDRAM с 128 на 256 MB.
Что для этого править надо? Знаю что в строке параметров загрузки ядра можно указать MEM=256MB , что-то ещё править надо? файл борды? там вроде как нет упоминания про SDRAM, там только nand...

прошу прощения, проблема по прежнему не решена.
Вот полный лог загрузки, рабочей системы:

сравнивал логи рабочей и не рабочей системы, зметил что в рабочей версии удивительным оразом всё последовательно настраивается, монтируются разделы UBI файловой системы. В нерабочем враинте всё совсем не так. Хотя конфиги практически идентичны и фалы борды одинаковые. Различаются версии ядер.

[Jury093]

прошу прощения, проблема по прежнему не решена.
Вот полный лог загрузки, рабочей системы:

более интересен лог нерабочей системы, фильтрация из .config (grep UBI, grep MTD, grep NAND) и куски файла борды, касающиеся нанда..

совсем не так. Хотя конфиги практически идентичны и фалы борды одинаковые. Различаются версии ядер.

пробейте по гуглю - может именно в этой версии ядра глючная подсистема (nand, ubifs)
