Linux rk3288 eDP+LVDS 双屏异显配置?
大家好:现在已经实现了edp+lvds双屏同显,一个走的vopl,一个走的是vopb。
接着在实现rk3288平台的双屏异显,使用最新的linux4.4.194内核
下面我贴出设备树 320 &lvds_in_vopl {
321 status = "okay";
322 };
323
324 &lvds_in_vopb {
325 status = "disabled";
326 };
327
328 &route_lvds {
329 status = "okay";
330 };
331
332 &lvds {
333 dual-channel;
334
335 status = "okay";
336 };
337
338 &lvds_panel {
339 status = "okay";
340 compatible ="simple-panel";

418 };
419 };
420 }; 请问一下大家linux下的双屏方案是怎么实现的呢? 请问一下大家linux下的双屏方案是怎么实现的呢? 求助...
并且现在两块屏幕只有一个/dev/fb0设备 111111111111111111111111 并且现在两块屏幕只有一个/dev/fb0设备 楼主解决了吗 只有一个fb咋异现啊
