Recalbox 8.0: (ERROR) : [SDL2] Fatal error initializing SDL2

@davidb2111 said in Recalbox 8.0: (ERROR) : [SDL2] Fatal error initializing SDL2:

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)

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!
