Other Parts Discussed in Thread: DM388
I am working on chip dm388.
LCD display live view is OK , but HDMI output is still failed.
(IPNC_RDK_V3.8.0)
I load "ti81xxhdmi.ko" success.
HDMI output 1080p on monitor.
There is a gray image 720x480 in the screen center.I can change gray image for different resolution. I guess hardware is OK.
But there is no any live image on HDMI. Live image only display on LCD.
Video link :
RSZA (2560x1920) ---> DUP_3MP1(VPSSM3) ---> gVdisModuleContext.mpSclrId ---> gVdisModuleContext.swMsId ---> gVdisModuleContext.displayId[VDIS_DEV_HDMI]
I can change swMsId resolution to change gray image resolution.
Could someone give me a sample code ?
I want know my setting is correct or not ?
And I find something strange.
This command is failed in my software.
echo vcompmux:hdmi > /sys/devices/platform/vpss/video0/nodes
VPSS_DCTRL: failed to enable node.
VPSS_VIDEO: (0): failed to disable old path
And I set this command :
echo 1,3/2/1/0 > /sys/devices/platform/vpss/display0/order
Command is ok but HDMI is still output nothing. Always output gray image.
I run the test program "saFbdevDisplayLoop"
HDMI output color bar on screen top. But live view never output on HDMI.
