Solved Can't get Composite to work (Raspberry Pi Zero)

[tikiandskull]

@mima2856 this is my config.txt, work with my bw 3.5'' composite screen

#hdmi_safe=1

disable_overscan=0

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

# comment to get jack audio
#hdmi_drive=2

#config_hdmi_boost=0

# force hdmi while the tv can take time before sending the signal on the hdmi output
#hdmi_force_hotplug=0

# uncomment for composite PAL
sdtv_mode=2

# uncomment for lirc-rpi
#dtoverlay=lirc-rpi

# if you plug your tv at the same time as your rpi and that the rpi switches from the hdmi or give a low resolution because tv had no enough time to initialize it
boot_delay=3

# uncomment if you don't want the rainbow at startup
disable_splash=1

# Overclock
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512

avoid_safe_mode=1

kernel=zImage

# NOOBS Auto-generated Settings:
arm_freq=1100
core_freq=550
sdram_freq=600
force_turbo=1
over_voltage=8
over_voltage_sdram=6
gpu_freq=250

hdmi_ignore_hotplug=1
framebuffer_width=320
framebuffer_height=240
overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0```

( je ne sais toujours pas mettre du texte dans une balise) :)

@tikiandskull Hi,

thanks for your config.txt. I tried it - but still no success
Behavior is still the same. Problem seems to be something else.

I plan on reinstalling recalbox, maybe I misconfigured something else.

Wiring should be OK if it works with raspian, am I right?

Best regards,
Michael

I quote some code :-)

@ian57 merci!

[tikiandskull]

@mima2856 sorry...

Hi,

for the record: I got it working.

I did setup recalbox on the RPi Zero, then I modified the config.txt and recalbox.cfg and now my TFT is working.

What i probably did wrong: I have a RPi3 and a RPI Zero. At first, my recalbox setup was simply taken from the RPi3 and put into the RPI Zero. Maybe that was the problem, I dont know for sure. I thought that the RPi3 and RPi zero are essentially the same hardware, so it wouldnt matter.

Best regards,
Michael

No they are not!!! That's why there are 3 Pi versions of recalbox! P0/1 Pi2 and P3 with different emulators activated. Making a Sd on a Pi3 will not work on a Pi2 or Pi0/1. So, do not suppose... be sure

[mima2856]

@ian57 yes, you are right of course. It did boot though, that's what got me confused
Next time I will read my hardware manuals properly, lol

[danno]

@ian57 is there a list or a files that shows what emulators are active on P0/1 vs Pi2 vs Pi3?
