我是使用的MDK4+JLINK V8调试FL2440,很简单的程序,我想法是把程序写到FL2440的MYAPP区,开始地址是OX00180000,SIZE是0X00380000;我也在MDK中使用了指令生成了BIN文件,但是通过DNW把BIN文件烧写到MYAPP区后通过设定MYAPP启动就不能启动,只看到LCD屏幕闪,响应的LED并没有显示,这种情况是APP区已经删除了,但是没有把程序写进去,或是下进去了跑飞了;当使用JLINK V8时候我设置:
ROM1 START: 0X30000000 SIZE:0X100000 RAM1 START:0X30100000 SIZE:0X100000
使用MDK FLASH选项的DOWNLOAD写程序时候出现下面的提示,是写FLASH算法出现问题,请问各位高手是怎么解决的:
