目前也使用Android 5.1 SDK增加編譯MIPI面板
但一樣發現MIPI信號無輸出
編譯上也看不出問題
另外- /*lcdc0 as PRMRY(HDMI),lcdc1 as EXTEND(RK1000)*/
- &lcdc0 {
- status = "okay";
- rockchip,iommu-enabled = <1>;
- rockchip,prop = <PRMRY>;
- /*rockchip,mirror = <NO_MIRROR>;
- rockchip,cabc_mode = <0>;*/
- power_ctr: power_ctr {
- rockchip,debug = <1>;
- lcd_rst:lcd_rst {
- rockchip,power_type = <GPIO>;
- gpios = <&gpio7 GPIO_A1 GPIO_ACTIVE_LOW>;
- rockchip,delay = <100>;
- };
- lcd_en:lcd_en {
- rockchip,power_type = <GPIO>;
- gpios = <&gpio5 GPIO_B1 GPIO_ACTIVE_HIGH>;
- rockchip,delay = <100>;
- };
- };
- };

這一段,修正成樓主方式,會開不了機
整體感覺設定後硬體控制都無動作(MIPI與GPIO)
請問有人有更詳細的說明嗎?
感恩 |
