散加载描述文件供ARM-ADS链接器使用，用来决定各个代码段和数据段的存储位置，下面为一个添加注释后的.scf文件例子：<br /><br /><br />代码:<br />;YL-LPC2294片内FLASH分散加载文件;Internal Flash 256kBytes， Address range:0x00000000～0x0003ffff;Internal SRAM 16KBytes， Address range:0x40000000～0x40003fff;External Flash 2MBytes，SST39VF1601， Address range:0x80000000～0x401fffff;External SRAM 512KBytes，IS61LV25616，Address range:0x81000000～0x81080000ROM_LOAD 0x0 ;ROM_LOAD:Name of the load region. ;0x0:Start address for ROM_LOAD region.{ ROM_EXEC 0x00000000 ;ROM_EXEC:Name for the first execute region. ;0x00000000:Start address for the execture region. { Startup.o (vectors, +First) * (+RO) ; Place all code and RO data into this exec region, ;and make sure the 'vectors' section from 'Startup.o' ;be placed first. } IRAM 0x40000000 ;The second execute region;start address is 0x40000000. { Startup.o (+RW,+ZI) ; Place all RW and ZI data from Startup.o here. } ERAM 0x81068000 ;The third execute region;Start address:0x81068000. { * (+RW,+ZI) ;All reset RW/ZI data to be placed here. } HEAP +0 UNINIT ;The fourth execute region;Start address:Follow the ;end of ERAM region. { heap.o (+ZI) ;All ZI data from heap.o to be placed here. } STACKS 0x40004000 UNINIT ;The fifth execute region. { stack.o (+ZI) ;All ZI data from stack.o to be placed here. }}<br /><br /><br />一般一个简单的分散加载描述文件包含三部分：Loader region、Execute region、Input section。各部分的格式及定义细节参见文件：ADS_LinkerGuide.pdf<br /><br /> |
