We are using following uBoot config line:
setenv tv 'setenv bootargs console=ttymxc0,115200
video=mxcdi1fb:YUV444,TV-PAL di1_primary tve'
setenv bootargs_base 'setenv bootargs console=ttymxc0,115200
gpu_nommu ${tv}'
can some please advise how we can enable Composite video output on i.mx53

Hello,Allen,
Try to set the following parameters in u-boot ( For Linux System )
u-boot >setenv bootargs_base ‘setenv bootargs console=ttymxc0,115200’
u-boot >setenv bootargs_mmc ‘setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootfstype=ext4 rw video=mxcdi1fb:YUV444,TV-PAL di1_primary tve’
u-boot >setenv bootcmd_mmc ‘run bootargs_base bootargs_mmc;mmc dev 1 ; mmc read ${loadaddr} 0x800 0x1800;bootm’
u-boot >setenv bootcmd ‘run bootcmd_mmc’

Hi Weidong
"The settings given are what my customer has already used. They don't work"
They would like to know how to turn on the composite?
