1. HDMI 와 VPSS 설정
아래설정은 기본적으로 DM8148로 SDK기준으로 작성했기때문에, TI BSP에 따라
달라질수 있겠다.
- HDMI (DM816x AM389x DM814x AM387x)
- HDMI Kernel 설정 및 모듈
- sysfs 설정방법
http://processors.wiki.ti.com/index.php/TI81XX_PSP_HDMI_Driver_User_Guide
- VPSS (HDVPSS) (DM814X AM387X) 관련사항 설정
HDVPSS의 경우 VIDEO IN/OUT을 담당해주는 Device로 현재 두개까지 지원이 가능하다.
만약 Display0 or 1 ( VOUTx) 변경하고 싶다면, 아래와 같이 sysfs을 이용하여, 변경해주자.
sysfs : display0
아래와 같이 shell program을 수정을하여, LCD or HDMI Mode로 수정을 하자.

Video in/out 설정방법
http://processors.wiki.ti.com/index.php/DM814X_AM387X_VPSS_Video_Driver_User_Guide_PSP_04.01.00.05#SYSFS_Software_Interfaces
VPSS와 VICP는 OS즉, BIOS6으로 기반으로한 Firmware를 사용한다.
다만, TI DSP가 C6xx 이 아닌 ARM의 Cortex-M3을 사용하여 TI용으로 별도로 Build 한 다음 Linux Booting 후에 이부분을 Loading 하는 방식으로 동작이 된다.

Device에서 아래와 같이 EDID를 분석을 하여 영상의 정보를 확인하자.
$ cat /sys/devices/platform/vpss/display0/edid
https://en.wikipedia.org/wiki/Extended_Display_Identification_Data#Enhanced_EDID_.28E-EDID.29
아래 프로그램을 이용하여 frame buffer를 TEST 해보자.
이제 제대로 설정이 되었다면, /dev/fb0, /dev/fb1 /dev/fb2 test
/home/root/dm814x-evm/usr/share/ti/ti-psp-examples/saFbdevDisplayPan를 이용하여 TEST
$ cd ~/dm8148/targetfs // device targetfs 이동
$ cd home/root/dm814x-evm/usr/share/ti/ti-psp-examples
$ ls

edma_test.ko minimal_playback saFbdevDisplayPan saFbdevMovingDisplay saLoopBack saLoopBackScale saUserptrDisplay
나머지 기능을 프로그램을 이용하여 다양한 TEST도 해보자.
2. DM8167 관련 경우
RDK 관련사항 수정
