这是LPC2200系列芯片内部Flash和外部Flash同时装载程序的分散加载文件使用示例。 ext_in.scf为分散加载文件，具体请读者自行分析，我们不对此示例提供技术支持。 在示例程序生成目标的test_ext_in.i32文件夹下有2个文件 / ROM_EXEC －－－ 写入内部FLASH / ROM_EXEC1 －－－ 写入外部FLASH (在选择文件的时候，请选择下拉所有文件*.*) 将两个文件分别写入后，选择跳线Bank0－FLASH，Bank1－RAM，BootSel－Inside 写入内部Flash，可用ISP方法下载。-This is the LPC2200 series chip Flash and external Flash loading procedures at the same time load the file using the sample dispersion. ext_in.scf for decentralized load the file, specifically requested the readers on their own analysis, we do not provide technical support for this sample. In the sample program to generate goals test_ext_in.i32 folder two files under/ROM_EXEC--- write the internal FLASH/ROM_EXEC1--- write external FLASH (in the choice of document, select the drop-down all the files*.* ) will write two files, select jumper Bank0-FLASH, Bank1-RAM, BootSel-Inside write the internal Flash, available methods to download ISP.
