Update:
- reference the link to get correct touch screen parameter
如何根据LVDS的时序规格计算TTL的前肩后肩。-CSDN社区 - turning the vga parameter
/sys/class/display/display0.VGA# echo 1280x800p-60 >mode - then my lvds tocuh screen is lighting, Ha! Ha! Ha!
感謝 madman 的support.
history:
-
自行編譯 LVDS 10.1吋螢幕的driver,i2c 通訊正常,firmware也有啟動,但是開機過程中,陸陸續續閃了三次,還是無法正常啟動
-
比較懷疑是firefly-rk3288.dts lcd0設定的問題,因為參考網路上有好幾組設法,只有目前這組,可以compile,沒有 error,但是卻無法正常啟動螢幕,我疑惑這些pin腳,在設計圖上都找不到,怪怪的.

附上dts與log, 請好心的人幫忙看一下
