Title: LIME2 with 7 and 4.3 LCD not working
Post by: jrgarcia on May 11, 2022, 02:15:26 AM
Hi all,

My LIME2 board is working fine with A20-OLinuXino-bullseye-base image if I connect it through HDMI, but 7" and 4.3" olimex LCDs are not working at all. No video, no light.

I'm using the 0.5 pitch 40 pin cable, and power up the LIME2 board with a 5V 2A power source.

Any suggestion? Thanks!

You need to run script "olinuxino-display" and enable LCD output. Also make sure the cable is properly oriented, it is possible to connect it in reverse. Also make sure you are using the proper connector at the back of the LCD, there is LIME and LIME2 connectors and these are mirrored - ensure that you are using the LIME2 connector at the back of the LCD.
