Activation cvbs/composite output on BananaPRO

[Zeiss]

Hello together,

 

I'm trying to activate composite output on my BananaPRO.

 

First of all, I've added setenv command to my boot.cmd:

setenv video-mode sunxi:1024x768-24@60,monitor=composite-pal,hpd=0,edid=0,overscan_x=32,overscan_y=20

then 

mkimage -C none -A arm -T script -d boot.cmd boot.scr

copied boot.scr to sd-card and reboot.

In u-boot I see:

Setting up a 720x576i composite-pal console (overscan 32x20)

but my monitor (DELL 2007FP with composite input) and my TV (Panasonic Plasma) are still black.

 

Any ideas?

 

Thanks!

Here some more infos.

 

boot.cmd:

setenv bootargs console=ttyS0,115200 earlyprintk root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait panic=10
setenv video-mode sunxi:1024x768-24@60,monitor=composite-pal,hpd=0,edid=0,overscan_x=32,overscan_y=20
setenv stdout serial,vga
setenv stderr serial,vga
