CCS/PROCESSOR-SDK-AM65X: load failed with CCSv9.x

Tool/software: Code Composer Studio

Hi Sitara support Team,

Relating to the following thread, I am facing the similar problem.
e2e.ti.com/.../789936

I have switched the new work space, but the result is same.

Our enviroment:
-CCSv9.0.1 and v9.1.0
-followed the example here: software-dl.ti.com/.../index_examples_demos.html

When I build the project with CCSv8, there is no problem.
However it cannot load the out file, and the this error message is shown.

Is this issue caused from CCSv9.x?

Could you please advise to solve this issue?
