Composite not working on 7.2

[digitaLumberjack]

Hi, not sure it works on PI4.

What i see is that you forgot the new option for pi4 in config.txt:

enable_tvout=1

Edit: yes you added it

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

I'm struggling on crt with pi4 right now, and i'm not sure it will work even with this option.

global.videomode=default must be in recalbox.conf btw

Are you sure you have the right cable ?

@digitalumberjack I do have the right cable. It worked with version 7.1 no problem. But since 7.2 nothing I do seems to work. I only get a black screen.
I'm not sure I have the global.videomode=default line. I'll have to check.

After a lot of research and trial and error I finally got it working but there was something that no one has mentioned before. I had to change my video driver in the config from "dtoverlay=vc4-kms-v3d-pi4" to dtoverlay=vc4-fkms-v3d. Trying different things I did manage to get video from the kms setting but it freezes at the recalbox slpash screen. (The one with the Pac-Man ghosts. Is there a way to get past the screen and load recalbox? BTW Thanks a lot for all your help!

Nobody mentioned it, because it shouldn't be necessary...
As far as I know (let me make something clear: I'm not a developer, I'm just an "ordinary" user) this tweak you mention is only necessary due to a bug with CEC PULSE EIGHT on KODI, see here:

• https://forum.recalbox.com/topic/23883/radpberry-pi4-kodi-black-screen-7-2/14
• https://forum.recalbox.com/topic/24211/maj-7-1-1-vers-7-2-1-bien-mieux-mais-pb-cec-pulse-eight

it freezes at the recalbox slpash screen

It may not be related to the composite cable, see here:

@zing is composite output still not working on 7.2.2?

[Zing]

@iga If it doesn't work automatically, make the changes suggested above and test, it should work.

[IGA]

@zing You mean change to dtoverlay=vc4-fkms-v3d ?

• yes, i've already try it - same effect as above - stuck at splash screen with pacman

I'm just wondering is this the case for everyone with 7.2.2 ?

[IGA]

Ok, i again formatted sd card and install ready image by balenaEtcher.
And so after change line to dtoverlay=vc4-fkms-v3d in config.cfg the picture is appear. ( this is important information, probably it should be added somewhere in the manual)

Everybody thanks.

@vj Bro, with this configuration and editing the part of the dtoverlay = vc4-kms-v3d-pi4 by dtoverlay = vc4-fkms-v3d-pi4 I managed to activate the video jack output, but it stays blocket in the loading screen the ghosts of pacman I found that it only works if I edit the dtoverly and add the line enable_tvout = 1 But it stays blocked, there is, who helps me, Sorry for English I use google translator I speak Spanish

[edwinsources]

@edwinsources Someone can give me the text of the config and the user config by email edwinsources@gmail.com so I just copy and paste to see if I'm doing something wrong

@edwinsources

• What is your version of Recalbox (say the version, don't say "latest")?
• Did you build your Recalbox yourself, or download a ready-made image from the internet, or did you buy everything ready-made?
• What is your hardware?
• Are you sure the problem is not the cable? The documentation explains that this can happen with wrong cables.

@zing recalbox 7.2.2 is the version I install Raspberry pi 4 I use the Raspberry image fot the install
