@fs
You're right! But the /boot/overlays folder is on a FAT32 partition, so I can't change the permissions. But r-x should be enough, right?

@acris
Still nothing, always a white screen even with chmod 777.
ps aux | grep fbcp gives:

  633 root     grep fbcp

Here is my config.txt file:

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

disable_overscan=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# comment to get jack audio
hdmi_drive=2

config_hdmi_boost=0

# force hdmi while the tv can take time before sending the signal on the hdmi output
#hdmi_force_hotplug=1

# uncomment for composite PAL
#sdtv_mode=2

# uncomment for lirc-rpi
#dtoverlay=lirc-rpi

# if you plug your tv at the same time as your rpi and that the rpi switches from the hdmi or give a low resolution because tv had no enough time to initialize it
boot_delay=3

# uncomment if you don't want the rainbow at startup
disable_splash=1

# Overclock
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512

avoid_safe_mode=1

kernel=zImage

#Waveshare 3.2 TFT Screen
#same resolution for hdmi and tft
hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2                
hdmi_mode=1                 
hdmi_mode=87                

dtparam=spi=on              
dtoverlay=waveshare32b:rotate=270,speed=82000000

And the file permissions for the overlays:

-rwxr-xr-x    1 root     root          2354 Aug  2 21:36 waveshare32b.dtbo
-rwxr-xr-x    1 root     root          2682 Aug  2 21:36 waveshare35a.dtbo

fbcp still outputs the same thing in the log file.

Here is the archive from the recalbox-support script: http://dl.free.fr/rluEHn909

I did create the S11fbcp file but I didn't change the permissions for the dtbo files !
I will try this this evening (I just got to work and I already want to leave :P)

@acris Thanks for your answer, but the screen is still white

I had already modified the file, and fbcp outputs this in the log file :

RECALBOX user.info fbcp[599]: Primary display is 320 x 240
RECALBOX user.err fbcp[599]: Unable to open secondary display

I guess I will have to way for the 4.1 unstable update to be back online, but I would really like to know what I missed

Hello everyone,

I have been struggling for hours with my new waveshare display that I ordered especially because I knew it would be compatible with recalbox.
I followed everything on the wiki page :

• Download, rename and copy the dtb files to waveshare32b.dtbo and waveshare35a.dtbo to /boot/overlays
• Edit the /boot/config.txt file to add the information from the wiki at the end of the file
• Download the fbcp file and copy it to /usr/bin after fixing the permissions

And I still end up with a white screen
HDMI works perfectly and the resolution is 320x240 as expected. What did I miss?

I looked everywhere for an answer, but no luck.

Thanks for your help!
