Do we assume you are running venus os on this Pi? What version are you trying?

Not sure it supports GPIO displays it was designed for HDMI.

After looking at another article have fixed the issue.i changed the cmdline file which got the display running.

replacement dwc_otg.lpm_enable=0 echo fbcon=map:10 >> console=tty1 consoleblank=300

original dwc_otg.lpm_enable=0 console=serial0,115200
