Hi All,
I try to put RPI4 B (4Go) (with Batocera 5.26) on a CRT screen but nothing work.
I had done exactly the same of RPI3 B (with Batocera 5.25) on it works well. For that I used :
In French :
https://github.com/recalbox/recalbox-os/wiki/Connectez-votre-recalbox-ecran-crt-avec-HDMI-(FR)
In English :
https://github.com/recalbox/recalbox-os/wiki/Connect-your-recalbox-to-a-CRT-with-HDMI-(EN)
For the rpi3b, I replaced the original config.txt in boot of Batocera (windows partition) by this one
#####################################################################
#Resolution of the mode custom DMT 87 HDMI for the games resolution
hdmi_cvt=1920 240 60 1 1 0 0
#Ignore the EDID of your TV (the CRT can send wrong informations)
hdmi_ignore_edid=0xa5000080
#Force the pixel encoding mode where 2 correspond to Full RGB
hdmi_pixel_encoding=2
#Desactivate the safe boot mode
avoid_safe_mode=1
#Allow overscan
disable_overscan=0
#avoid interférences by boosting the HDMI signal
config_hdmi_boost=4
#Force the sound on HDMI
hdmi_drive=2
#Select the HDMI CEA group
hdmi_group=1
#Define resolution to CEA 6 = 480 interlaced
hdmi_mode=6
#Kernel
kernel=boot/linux
initramfs boot/initrd.gz
#Use the HDMI even if no cable is connected
hdmi_force_hotplug=1
#Memory config
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512
#Audio config
dtparam=audio=on
#Delay boot
boot_delay=3
##################################################################
and I modified some lines into batocera.conf by :
system.es.videomode=CEA 6 HDMI
global.videomode=DMT 87 HDMI
For the RPI4B I did the same, The only thing I have added, I took the modified config.txt of the RPI3B and added the following line at the end :
dtoverlay=vc4-fkms-v3d
But It doesnt work …
Someone have a solution or an idea ?
Thank you :)
