And to force boot without detecting case, you may:

1. set case=none:1 in /boot/recalbox-boot.conf
2. execute rm -rf /overlay/upper/*

and reboot

I tried this, but still the screen remains black.

Before the modified tester, the output was:

CRC error
198

Hi @fh1105

Great news, that helps me a lot. I will include a fixed piboy-tester that will not wrongly detect a PiBoy when something is connected to GPIO.

At the moment, you can cleanup overlay and set case=none:1 to disable autodection.
The fix will be included in the next release a few days (weeks)

Hum, what type of screen do you have ?
Could you please execute cat /sys/class/drm/card*/modes and put result here ?

cat /sys/class/drm/card*/modes

It's a HDMI-connected HD screen – normal 'office type'.

cat /sys/class/drm/card*/modes

returns nothing at all.

But here's me exploring that directory:

# pwd
/sys/class/drm
# ls
card0           card0-HDMI-A-1  renderD128      version
# cd card0-HDMI-A-1
# ls
device     edid       modes      status     uevent
dpms       enabled    power      subsystem
# cd modes
-bash: cd: modes: Not a directory
# ls
device     edid       modes      status     uevent
dpms       enabled    power      subsystem
# cat modes
# cd ..
# ls
card0           card0-HDMI-A-1  renderD128      version
# cd card0
# ls
card0-HDMI-A-1  device          subsystem
dev             power           uevent
#


(modes in card0-HDMI1-A-1 is empty)

By the way: amazing support, @davidb2111! Thank you very much!!

Hi @fh1105

Seems edid does not report modes. Could you force the mode within /boot/recalbox-user-config.txt.

hdmi_group=1
hdmi_mode=X

where X should be:

• 16 for 1080p
• 4 for 720p
• 1 for VGA mode (640x480, as a fallback)

Once started, if still no display, try adding this setting:

hdmi_ignore_edid=0xa5000080

Hope this help.

Also, do you know the resolution of your TV?

Hello!

Just a brief update, as I solved it by simply removing everything from my GPIO ports, and wiring my arcade buttons to a

Zero Delay Arcade USB Encoder

– which then connects to the RPi's USB ports.

All good now! Thank you, and keep it up!
