请问怎样把IAR生成的bin文件下载到板的nandflash里面然后运行呢？
我的板子是ARM9的板子，uboot 引导linux启动的现在我需要跑裸机程序，由于板子没有norflash，所以不能用jlink直接下载，裸机程序我是用jlink在ram里面调试好了的都好用
我想是用IAR生成bin文件，然后用UBOOT下载到ram里面然后运行，现在是我生成的文件下载到地址0x40000000之后，go 0x40000000，板子没有反应，不知道有没有做过类似方案的前辈？ IAR有两总编译方式，一种是NOR debug 一种是sdram debug，两种不同的ICF,我用哪一个呢？ 由于你的板子没有norflash，所以不能用NOR debug,而你又想下载到nandflash中运行，sdram debug也不行，需要自己写一个配置文件。还有要注意异常向量表的问题，发生中断的时候程序会跳到0x0去 回复【2楼】llf021421马中马

哦，这样啊，我也是用U BOOT下载到SDRAM里面运行的，这样能用sdram debug的配置吗？ /*###ICF### Section handled by ICF editor, don't touch! ****/

这是sdram的ICF，不知道为什么生成的.BIN文件好大，好几百MB 好了，弄出来了

ICF改了上面这些东西，然后TFTP 0X40000000，然后GO 0X40000000，裸机程序就跑起来了，
