raspberry b+ RCA

Sat Nov 22, 2014 6:28 pm

Hello
I'm trying to get composite output to work but nothing works

config.txt

Code: Select all

# For more options and information see 
# http://www.raspberrypi.org/documentation/configuration/config-txt.md
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
sdtv_mode=0

#uncomment to overclock the arm. 700 MHz is the default.
arm_freq=1000

start_x=1
core_freq=500
sdram_freq=600
over_voltage=6
safe_mode_gpio=4
TV=1
hdmi_ignore_hotplug=1

cable was ok, it was self made. Anyway setting sdtv to 2, gpu_freq = 350 and adding 256mb for graphic fixed problem :)
