Hello!

 

I recently started setting my board up, and came across all the information needed to enable the LCD use for it. For info, I've updated to 5.20.

 

I have gone through the whole process to change the script.bin to fex, edit, change back, copy and sync. The changes are saved, I have even made a copy of the script.bin to script.fex in order to see if the new script contains the changes I made. All is there. It seems to be the problem another user had in this thread:

 

http://forum.armbian.com/index.php/topic/841-bananapro-lemaker-5in-lcd-legacy-kernel/

 

 

In this case I chose the lcd_if=4 since it is what they provide at sunxi, but it didnt work. I then changed the value to lcd_if=0. SInce it didn't work I changed it to internal DSPI and then external after reading a bit about them.

 

I'm a bit lost as to what to do. I hope I've made myself clear.

 

All in all, thank you for your support. Great community!

I should probably add that I changed the whole script.bin first with what LeMaker provided. Since that didn't work I then took the path to access the fex file and change the parameters myself.

Hi,

 

Sooner or later I also want to attach a 7" display to my SBC, but it should be connectable to Raspberry 2 & Banana without HDMI (this is were I am uncertain about DSI and number of pins) until then I follow others.

In this thread you might find some ideas to solve your problem ?

 

Cheers

Tido

LeMaker fex configuration for 5in display works for me. The problem I had was from typo I made manually copying values. There are 4 sections that have to be overwritten, then you have to load ft5x_ts module to get touch working.

So I have decided to post a bit more detailed information, maybe doing this will also help me get an idea of where my mistake is
Thanks for all answers and support. It's very appreciated.

 Save changes in nano

Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ?

yes

File Name to Write: script.fex.new  

ENTER

FEX2BIN and then link script.bin to new bin

jake@bananapipro:/sunxi-tools$ sudo fex2bin script.fex.new script.bin.new
jake@bananapipro:/sunxi-tools$ sudo cp script.bin.new /boot/bin/custom.bin
jake@bananapipro:/sunxi-tools$ sudo ln -sf /boot/bin/custom.bin /boot/script.bin
jake@bananapipro:/sunxi-tools$ sync
jake@bananapipro:/sunxi-tools$ sudo reboot

Screen turns on but doesn't display anything (black display), backlight works, ssh works fine.

 

Ideas?

Well, after wracking my brain like crazy i reconnected the display, tripled checked the hardware. It's working now so thanks. At least someone can read this and learn how to set the display hahaha

 

Thanks for all the help!
