每次DDR校验后，要手动修改flash_header.S，好麻烦，所以写了个C程序自动转换，下面是代码，不足之处请指教。 编译：gcc -o ddr_convert main.c 使用：./ddr_convert Elmo.inc
#include #include #include #include #include #define FILENAME "Elmo.inc" int main(int argc,char *argv[]) { FILE *fp; char StrLine[1024]; char *ptr; char reg[11],val[11]; unsigned char item=1; unsigned int len; char *file_name=FILENAME; if(argc>1) file_name=argv[1]; printf("inc file:%s ",file_name); if(access(file_name,R_OK)!=0){ printf("file /'%s/' can't be read! ",file_name); return -1; } if((fp = fopen(file_name,"r")) == NULL){ printf("open file /'%s/' error! ",file_name); return -2; } while( fgets(StrLine,1024,fp)){ //printf("%s ", StrLine); if(0!=strncmp("//", StrLine,2)){ //printf("%s", StrLine); if(0==strncmp("setmem /32", StrLine,10)){ //printf("%s", StrLine); ptr = strstr(StrLine, "0x"); strncpy(reg,ptr,10);reg[10]=0; //printf(" %s", reg); ptr = strstr(ptr+1, "0x"); strncpy(val,ptr,10);val[10]=0; //printf(" %s ", val); if(0==strncmp(reg,"0x020e0" ,7)){ printf("MXC_DCD_ITEM(%d,IOMUXC_BASE_ADDR + 0x%s,%s) ",item++,®[7],val); } else if(0==strncmp(reg,"0x021b0" ,7)){ printf("MXC_DCD_ITEM(%d,MMDC_P0_BASE_ADDR + 0x%s,%s) ",item++,®[7],val); } else if(0==strncmp(reg,"0x021b4" ,7)){ printf("MXC_DCD_ITEM(%d,MMDC_P1_BASE_ADDR + 0x%s,%s) ",item++,®[7],val); }else{ printf("get a wrong item... "); } } } } item--; len=item*8+4+4; //printf("len=0x%x ",len); len=(len>>8)|((len&0xff)<<8); printf("0x%x ",len); len=item*8+4; //printf("len=0x%x ",len); len=(len>>8)|((len&0xff)<<8); printf("0x%x ",len); fclose(fp); return 0; }
