另外有關 TV Out 的參數設定和說明： https://community.freescale.com/thread/301648

Sorry, I misread the question. I thought you are using ADV7180.
for your case, I think it may be the problem of bootarg.
According to the BSP release note, there is an example for TVE output.
"video=mxcdi1fb:YUV444,TV-1080P30 di1_primary tve"
NOTE: GBR24/RGB565/YUV444 etc represent the display HW interface format, typical value for different display devices is like below:
TVOUT: YUV444
VGA: GBR24
HDMI&DVI: RGB24
CLAA WVGA LCD: RGB565

after enable tve, below video modes will be added into di1 FB mode list:
TV-1080P24: D:1920x1080p-24
TV-1080P25: D:1920x1080p-25
TV-1080P30: D:1920x1080p-30
TV-1080I50: D:1920x1080i-50
TV-1080I60: D:1920x1080i-60
TV-720P30: D:1280x720p-30
TV-720P60: D:1280x720p-60
TV-PAL: D:720x576i-50
TV-NTSC: D:720x480i-60


so for your case, please try: 
"video=mxcdi1fb:YUV444,TV-PAL di1_primary tve"
