IMX7ULP EVK LP Boot Mode M4 halts

I'm trying to test IMX7ULP-EVK board (REV B1) using the image files in L4.9.88_2.0.0. The demo image which is power_mode_switch starts working in LP-Boot mode and spits out some messages that working task is running. But it halts before it can proceed to the power mode switch commands. 

I'm wondering, is there any specific image file just for testing M4 in LP-Boot and also is there any instruction on how to boot the A7 by M4 in LP-Boot mode?
