modify vector checksum value in *.bin

hello, Sir

I have successfully compiled and generated binary (executable) File using makefile and imported project from Renesas Web Compiler on e2studio.

But it is not working.(Not blinking an LED (of LED blinking program)).

Is that a problem of vector Checksum in binary File?

If Yes,why need to modify checksum? How can I modify this checksum using which tool ?

waiting for your reply,

Thank You.
