I'm using i.MX6ULL 14x14 Evk. 

I succeeded to build Yocto and my evk can boot-up.


Now, I want use small OLED disaply.

My small OLED display is SSD1306.

I found kernel driver code in below path


I connected it to ECSPI4 as below picture with help of my H/W member.

Small OLED on Evk.


Resolution is this OLED is just 128x64. 

Can I use this with "core-image-sato" with X11 ? Or should I choose other bb?

I need to draw some image and text in various font.


How can I enable this display?

Device tree need to be modified? Or, Kernel need to be modified?

I have no idea to start porting this.


Any information needed. Thank you.
