HDMI 및 VPSS 설정

1. HDMI 와 VPSS 설정

아래설정은 기본적으로 DM8148로 SDK기준으로 작성했기때문에, TI BSP에 따라
달라질수 있겠다.

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.

아래와 같이 HDVICP와 HDVPSS의 Firmware도 변경이 가능하며, HDMI 설정가능

VPSS와 VICP Firmware

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.

HDMI EDID 분석

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

HDMI 기본 VIDEO TEST

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
ReadMe        minimal_capture   saFbdevDisplay     saFbdevHdmiDisplay    saFbdevScalingDisplay  saLoopBackFbdev  saMmapDisplay     saWatchdog
edma_test.ko  minimal_playback  saFbdevDisplayPan  saFbdevMovingDisplay  saLoopBack             saLoopBackScale  saUserptrDisplay

나머지 기능을 프로그램을 이용하여 다양한 TEST도 해보자.
