Hello, I'm trying to add a E50RG84885LWAM520-CA <https://focuslcds.com/product/5-0-tft-display-capacitive-tp-e50rg84885lwam520-ca>TFT LCD to my BeagleBone Black Wireless. It has an ILI9806E controller IC.
I can't seem to get the correct polarity for the DE signal. The controller is expecting an active LOW DE signal. I have tried setting de-active = <0>; to my devicetree overlay, but it seems that setting is ignored. When I measure what the output of the BBBW is, all other control signals look correct except for that one. My overlay is enabled in /boot/uEnv.txt: dtb_overlay=/lib/firmware/RB-TFT-PROTOTYPE-V1-00A1.dtbo Apart from measuring the output, I can also see with fbset that the resolution and bpp settings have been accepted, so the .dtbo is definately loaded at boot... My whole devicetree file is here: https://gist.github.com/RasmusB/cea0cb4c2f69259497b3e37ac0347e76 Any ideas on where I should look next? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
