Hi,

 

I cannot get the iMX8 EVK to display on the OLED display. I have followed all instruction in the application note : "Quick Start Guide for MX8-DSI-OLED1 for i.MX 8M Evaluation Kit"

I am using the default state of the EVK i.e android  image and the settings of the DIP switches are all for boot internal from eMMC. The Mini SAS cable is securly inserted into the display and the SAS connector near the CPU

 

I Cannot see any clues in the boot messages form the serial console either. only ones of possible significance are listed below, I also note in the kernel command line it appears that HDMI is still selected. (also below)

 

Any help appreciated
