How to see the IPU/DSP firmware logs from the serial port terminal

Hi 

I need to implement the CVBS driver(tw9990) in IPU1 , the source code is based on SDK – 02_08_00_00.

The test evm is VAYU EVM XC5777X ， I want to see the debug logs of the firmware of  IPU1 , How can I see the logs from serial port terminal?

The IPU1 firmware is dra7xx-rvc-m4-ipu1.xem4 which is downloaded by uboot.  Now I only can see the uboot logs from uart serial port 1,  Is it possible to see the IPU1 firmware debug logs from the uart serial port? How can I enable it?

I see there is  Vps_printf(...) API in the SDK -02_08 source code, I think the RemoteLog_init() is used to initialize the remote core debug logs. But I can't see any logs after the firmware is downloaded.
