Configure 2.8" Screen with latest batocera

Pi4Ever

Hello everyone I'm new here, to see if anyone can help me.
I'm trying to run the latest batocera version on a PI3 with a 2.8 "screen (the screen is compatible with opengl, resistive and connected via GPIO) but I can not configure it correctly, I can not run the FCBP, which although installed and detected (the screen changes from white to black when I turn it on and i have the system music) is still without image, with retropie works fine, any charitable soul that can help me? I would be very grateful, thanks to everyone in advance!

Pi4Ever Okay, we will try something

-Format your micro SD card in Fat32 format and burn the image of Batocera

-Once the burning of the image is complete, go to your micro sd card and you will find a file named config.txt

-Open it with Notepad ++ and add this

dtparam=spi=on
dtparam=i2c1=on
dtparam=i2c_arm=on
#forcing HDMI output at TFT screen resolution to be able to make the FB copy
#resolution configuration
hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87
# working config for speed
# 900 Mhz -> 48000000
# 1Ghz -> 35000000
#modification of the speed   
dtoverlay=pitft28-resistive,rotate=90,speed=22000000,fps=60

-Save the file

-Eject and test on your Pi

Thanks, i tried it and got a black screen again, ill show you the config.txt of retropie, with this, works fine:

For more options and information see

Some settings may impact device functionality. See link above for details
uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1
uncomment this if your display has a black border of unused pixels visible
and your display can output without overscan
#disable_overscan=1
uncomment the following to adjust overscan. Use positive numbers if console
goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
uncomment to force a console size. By default it will be display's size minus
overscan.
#framebuffer_width=1280
#framebuffer_height=720
uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1
uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87
hdmi_cvt=320 240 60 1 0 0 0
uncomment to force a HDMI mode rather than DVI. This can make audio work in
DMT (computer monitor) modes
#hdmi_drive=2
uncomment to increase signal to HDMI, if you have interference, blanking, or
no display
#config_hdmi_boost=4
uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on
Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi
Additional overlays and parameters are documented /boot/overlays/README
Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
overscan_scale=1
dtoverlay=pitft28-resistive,rotate=270,speed=80000000,fps=60
i have no more ideas...
Thank u a lot!
And sorry about my English... jeje
