Hi Ti,
I have a similer issue. But I do know how to generate the EDID file following the answer from 270
tyrael
My LCD panel has worked at last! I think EDID is the key problem.Kernel won't drive the lcd if it can't get the panel information by EDID port or the built-in bin files.Unfortunately my board has neither of those.After I made my own edid file based on the panel's datesheet ,the lcd got work!Here is what I did:
1 generate 1280x800 EDID file as Documentation/EDID/HOWTO.txt explains and copy it under /lib/firmwar
2 set CONFIG_DRM_LOAD_EDID_FIRMWARE=y in kernel configuration
3 add drm_kms_helper.edid_firmware=edid/1280x800.bin to kernel command line .
What I did is to download the EDID files from https://github.com/torvalds/linux/tree/master/Documentation/EDID to my BeagleBone Black and make it. An error happened here see output below. I know I must miss some thing, can tyrael or anyone help me about this?
