No Algorithm found for: 30000000H - 300041EFH

  在你使用RealViewMDK下载程序的时候有遇到过类似于如下的错误信息吗?

  Load "D:\\david\\project\\farsight\\LED_UART\\obj\\led_test.AXF"

  No Algorithm found for: 30000000H - 300041EFH

  Erase skipped!

  此时也会弹出“Error:Flash Download failed – ARM920T”的错误对话框。

  从错误信息中,可以看到RV要找以0x30000000开头的地址空间的Flash下载算法。但这个空间不是Flash地址空间。而是内存空间。这说明,在这个项目中使用的Scatter文件是基于RAM内存空间的。现在打开工程的option对话框的Linker标签看看,果然是没错!

  这个问题有两种解决方法:

  1)你既然选择了基于内存的加载方式,应该在Utilities标签中,取消“Update Target before Debugging”,这个选项只能在Flash加载方式中使用。参考如下图。

  2)采用基于Flash的Scatter加载文件。
