DDR Test suite binary file can not start

Associate II

Try to conduct the DDR test to my STM32MP135 customized board,  following the instruction in the DDR test util:

while after successfully download the test binary file, the test code didn't start,  I am using serial only for this test (not usb + uart),  seems the parameter  –-start 0x01 not accepted,  anyone has an idea of what is going on with it?

following is the full log:
