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..
