LPC802 debug failure with arm ds

I import a LPC802 hello_world keil example into arm ds. It could build pass and generate .axf file.

But I have met an error when debugging.

Here is my debug configuration:

When I click debug, here is the error log :

And the window was switched to Disassembly tab:

When using keil,  this project could build and debug successfully. I don't know why encounter error in arm ds. Because all the files and options are same, and the compilers are both arm compiler 5.

Does anyone know the reason of this error ? It will be appreciated for any suggestion.
