When I tried to load fbtft driver on my Banana Pro I got the errors abrove. How could I fix this? I'm using WaveShare 3.5inch RPi LCD.

Ok, I successfuly load the device now. However, there are just some strange lines on the tft... I am using this screen: http://www.wvshare.com/product/3.5inch-RPi-LCD-A.htm and my /etc/modules are as follow:

    # /etc/modules: kernel modules to load at boot time.
    #
    # This file contains the names of kernel modules that should be loaded
    # at boot time, one per line. Lines beginning with "#" are ignored.
    # Parameters can be specified after the module name.

EDIT: Okay I found the problem out. Just because the wrong parameters for flexfb make the output only use a tiny part of tft. However, on my Raspberry PI this seems to work fine... And I ckecked for wiki for flexfb and I can't find my WaveShare TFT there. So how should I modify the parameters? Another problem is, how can I put my console output (i.e. ttyN, demsg, etc.)to '/dev/fb2'? Seems like the fbcon put it's output to /dev/fb1.

Could you help...? Thakns for lot.

bananapi pro's gpio is different from raspberry pi B+

Thanks for answering,

So there are nothing I can do? Could I modify the Device Tree file of FBTFT and make it suitable for Banana Pro?

[notro]

Based on the comment by @FishTest , you must find suitable gpio numbers for these:
gpios=reset:25,dc:24
gpio_pendown=17

[magicnat]

The screen can display now.

However there are still something wrong... there were something moving in the small dark area while booting, I think that might be demsg...

Is the parameters for flexfb wrong?

[notro]

Is the parameters for flexfb wrong?

Most likely, yes.

Closing issue since there has been no activity for more than 2 months. Reopen if needed.

Please,
I need to run the same screen in my Banana Banana Pi or M2. Someone successful?

[rogercorrea]

I could run in Banana Pi LeMaker.
Set up steps 1 and 2 of this link by changing FB01 to FB02 both in /etc/X11 as /usr /share/X11.

My /etc/modules was exactly the same as yours. Strange that only worked in fact restarted after a few times.

@notro , I think this makes your library also Banana Pi support. =)
