@acris ok guys I understand my mistake, I put all the initial configuration in recalbox/share/system/ recalbox.conf file and not in boot....

Now it's working fine!
Thanks again for your help

Regards

Yes sure here below the pictures:

Model is PITFT Mini Kit - 320x240 2.8
TFT + Touchscreen for Raspberry PI
Resistive version
I buy the screen with GPIO connector 26 points
If the picture don't appears internet link
http://www.ohmeron.be/fr/prototyping/lcd-tft/pitft-mini-kit-320-x-240-2-8-touchscreen-for-raspberry.html

My RPI:
RPI2 Model B V1.1 (2014)

No fb1 in dev, only fb0

Then something strange, the following lines:

dtparam=spi=on
dtparam=i2c1=on
dtparam=i2c_arm=on

Are always replaced by:

dtparam=i2c_arm=on
dtparam=i2c_arm=on
dtparam=i2c_arm=on

After reboot....

Thanks again guys

Hello!!
Yes the pitft28-resistive.dtbo exist in sdcard at overlay directory

the command

# # ps aux | grep fbcp
# root       855  0.0  0.0   2340   228 pts/0    S+   15:51   0:00 grep fbcp

thanls for your help

Hello guys,

I want to use my piTFT resistive screenc 320x240 TFT with my RPI2 and recalbox 6.1.1,

I put the following lines via recalbox web UI following the page:
https://github.com/recalbox/recalbox-os/wiki/TFT-Screen-SPI-Bus-(EN)

Overlay config with standard values for fb copy

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

Enable fb

Disable GPIO

Video settings

## Set game resolution for emulators
## select your mode from the command : tvservice -m [MODE]
## CEA 5 HDMI : 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced 
## CEA 4 HDMI : 1280x720 @ 60Hz 16:9, clock:74MHz progressive
## use 'default' for using the default resolution
## use 'auto' : switches to CEA 4 HDMI if supported, else keep the current resolution
## (string)
##global.videomode=CEA 4 HDMI
global.videomode=default

## Shader set 
## Automatically select shaders for all systems
## (none, retro, scanlines)
global.shaderset=none

## Once enabled, your screen will be cropped, and you will have a pixel perfect image (0,1)
global.integerscale=0

## Set gpslp shader for all emulators (prefer shadersets above). Absolute path (string)
global.shaders=

## Set ratio for all emulators (auto,4/3,16/9,16/10,custom)
##global.ratio=auto
global.ratio=4/3

The screen remain white ...
Any additional idea?

Best regards
