Pi2Scart on Pi4, no video signal

EvilSam

Hello!

Please, I need some help on this one! I´m using a Pi4 8GB model with virtualman´s image on it which runs perfectly on my HDMI display.

As I´m building an arcade cabinet with the Pi inside, I´ve decided to get a 21" Sony Trinitron CRT to get the best possible results.

My pi2scart arrived 3 days ago, ever since I´m trying to get a signal to my crt!

I don´t know what I´m doing wrong, I´ve followed the instructions on the acradeforge site and have been browsing the internet for the last few days, with no success :(

All I get is a black screen, I´ve tried changing stuff in the config.txt file but nothing.

I´d be very grateful for some hints!

Here´s my config:

For more options and information see

Some settings may impact device functionality. See link above for details

Avoid Warnings symbols (Not Recommended)

#avoid_warnings=1

disable_splash=1

#Ensures the LCD is not the default display
display_default_lcd=0

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)

uncomment to define the custom video mode over hdmi

https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

command hdmi_cvt=<width required> <height required> <framerate required> <aspect no> <margins 0-1> <interlace 0-1> <rb 0-1>

aspect ratios numbers fro hdmi_cvt command 1=4:3, 2=14:9, 3=16:9, 4=5:4, 5=16:10, 6=15:9

#hdmi_group command options 0/(Auto) / 1(TVs CEA) / 2(Monitors DMT)
hdmi_group=1
hdmi_group=1
hdmi_mode=16
#hdmi_cvt9=800 480 60
#hdmi_cvt12=2160 1440 60
hdmi_ignore_edid=0xa5000080

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=2

uncomment to define the aspect ratio for composite video output

#4:3 is 1, 16:9 is 3
#sdtv_aspect=3
#uncomment to overclock the arm. 700 MHz is the default.
#uncomment to enable custom overclock settings
#arm_freq=2000
#gpu_freq=600
#over_voltage=6

Uncomment some or all of these to enable the optional hardware interfaces

#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

Uncomment this to enable infrared communication.

#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

Uncomment this to enable the lirc-rpi module

#dtoverlay=lirc-rpi

Additional overlays and parameters are documented /boot/overlays/README

Enable audio (loads snd_bcm2835)

dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=384
gpu_mem_2048=512
gpu_mem_4096=512
#overscan_scale=1

Enables USB BOOT MODE on PI3B

program_usb_boot_mode=1
enable_uart=1

[pi4]

Enable DRM VC4 V3D driver on top of the dispmanx display stack

dtoverlay=vc4-fkms-v3d

#Onboard analogue audio options in config.txt (3.5mm jack) https://www.raspberrypi.org/documentation/configuration/config-txt/audio.md
#Crackle sound fix: Use of the two below options
#audio_pwm_mode=0
#audio_pwm_mode=2

By default, a 1.0LSB dither is applied to the audio stream if it is routed to the analogue audio output. This can create audible background "hiss" in some situations, for example when the ALSA volume is set to a low level

disable_audio_dither=1
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1 #240p

I really hope someone has the time to look over this and maybe spot the error(s), it´s driving me nuts!

Thanks, Sam

We don't support 3rd party images, as outlined in https://retropie.org.uk/forum/topic/3/read-this-first. Use the image from retropie.org.uk/download or ask the image author(s) for support.

Sorry, I didn´t read that mb.

But I will try to get it running with the officcial retropie image!

Thanks for replying anyway :)
