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,
