Hello @jianqingping 

may I know how you are building the petalinux project?

1. Are you building it using template flow or building on Xilinx EVB?

2. Which Vivado and Petalinux version are you using to test this Multi scaler demo?

Regards

Kunal

@kvasantr  Hi, thank you for your help.

1.  I am  building it using template flow  on zcu106?

2. I used  Vivado2019.2 and Petalinux 2019.2   to test this Multi scaler demo.
