일반 SDRAM 128M를 쓰고 싶어요...

안녕하세요...

SDRAM을 128MByte 를 쓰려고 합니다..

현재 ez-x5 보드의 커널을 기본으로 쓰고 있는데요...

linux/arm/mach-pax/ez-x5.c 파일에서

// SDRAM 을 선언하는 부분이다. -- 64Mbyte
SET_BANK (0, 0xa0000000, 64*1024*1024);
SET_BANK (1, 0xa4000000, 64*1024*1024);
//mi->nr_banks = 1;
mi->nr_banks = 2;

와 같이 했구요.. arch/arm/kernel/setup.c 파일에서

#ifndef MEM_SIZE
//#define MEM_SIZE (64*1024*1024)
#define MEM_SIZE (128*1024*1024)
#endif

와 같이 하였습니다..

그런데 컴파일을 하니 아래와 같이 커널 패닉이 나오네요..

메세지를 보면 일단 메모리는 128MB 로 된것 같은데 커널 패닉이 나오는 것으
로 보아...
다른 세팅이 더 있는것 같은데 혹시 알고 계신분 있으면 알려주심 감사하겠습
니다..

ps) 메모리를 128메가 장착한 상태에서 ez-x5와 같이 64MB로 세팅해서 쓰면
잘 돌아갑니다...
