Help with composite out.

[Politician]

Hey, thanks for the response! I've been working the past few days to get Putty and WinSCP up and running, however I'm having a problem with the command mount -o remount,rw /boot as it doesn't seem to be changing anything? I also don't have quite a clear understanding on where my config file should be, I understand it's write protected but in the boot folder of recalbox, I find no such file, even after following the "Access a partition for writing" section of the tutorial you helped me with. Could you please clarify this a bit more, I really appreciate the help so far.

@Politician

the command mount -o remount,rw /boot as it doesn't seem to be changing anything

This command gives you write permission: If you are able to edit and save the config.txt file, then it is working, if not, you are doing or typing something wrong.

but in the boot folder of recalbox, I find no such file

The path is: /boot/config.txt
It is only accessible via SSH (it is not possible to access directly with an adapter, the system must be working for the file to be accessible).

If you are using WinSCP, go to root (move up the folder hierarchy until you can't move up any more), and there you will find the boot partition, inside it, the file config.txt.

The past few days, I've familiarized myself with this and it's helped a ton, I've leaned a lot about WinSCP and SSH but I'm still encountering a problem. I'm getting audio but no video, video is at best, flickering black and white static/fuzz/noise. I've tried swapping the yellow/white cables, I've tried every combination, even multiple TVs and still no video, only audio. I've even tried other software, formatting and re-formatting to test Lakka/Raspian/Retropie and still no composite video.

I may be mistaken, but, it seems that the cable is the problem, did you test it with a multimeter, as the tutorial says?

Caution, on camcorder cables, the video output may be on the right (red) audio jack.

Also, the type of cable required is not really common.
It is preferable to test with a Multimeter, in order to be sure that the cable you plan to use is
corresponding to the diagram proposed above (an inversion of Ground and video on the jack
leads to a jumping black & white image, sign of an unsuitable cable).

[Politician]

I did not because I do not own a multimeter. My cable is an Adafruit A/V and RCA (Composite Video, Audio) Cable for Raspberry Pi [ADA2881] so I just assumed it would be correct and good for the Pi.

@Politician This does not yet rule out the possibility of the cable being defective, for example.
There are few possibilities:

• Or the cable is defective,
• Or you are setting something up wrong.

What options have you modified?

[Politician]

This is my config, the things I've added are at the bottom of the config.

@Politician You forgot a detail that says in both tutorials.

This tutorial says:

• Finally, add hdmi_ignore_hotplug=1 to force the composite output.

And this tutorial says:

• hdmi_ignore_hotplug
  Setting hdmi_ignore_hotplug to 1 pretends that the HDMI hotplug signal is not asserted, so it appears that a HDMI display is not attached. In other words, composite output mode will be used, even if an HDMI monitor is detected.

In other words:
Uncomment this line (remove the # from the beginning of the line):
# hdmi_ignore_hotplug = 1

[Politician]

My mistake, I should have mentioned I have tried that and still ended up with a flickering/junk screen. I think at this point it might be a bad/defective cable.

@Politician Maybe, but I can't guarantee it, unfortunately just testing to make sure ...
