20250910榮品RD-RK3588-MID開發板在Android13系統下解決點卡迪的屏閃屏的問題
2025/9/5 15:44

緣起：榮品RD-RK3588-MID開發板在Android13系統下解決點卡迪的屏。
按 POWER按鍵關機之后，2s之內再次短按 POWER按鍵，開機之后屏會抖動。
2s后短按 POWER按鍵，開機之后屏顯示正常。

解決步驟：屏蔽掉11 29后面的初始化代碼。
據說后面的代碼是控制端使用的？
最好還需要修改一下：de-active的極性為1。

請問 DTS中的 de-active 這個參數 ? 是干嘛用的呀？/配置啥的？

@2025?一般【我見過的屏都是】 0x11 和 0x29命令之后就沒有命令了。
請問一下命令是必須的嗎？做什么用的？

// Video Mode Enable--------------------------------------------------
writecomm(0xB7);
writedata(0x59);
writedata(0x02);
//----------------------------------------------------------------------

writepattern(0xFF,0xFF,0xFF);

不需要
請問這些指令是干嘛用的？
望文生義：看名字是視頻模式使能的？感覺很重要的！[破涕為笑][疑問]

RD-RK3588-MID開發板。
使用卡迪的屏。

關機之后。
串口打印：[ ? 49.896765][ ? ?T1] reboot: Power down

如果 2秒之內按 POWER按鍵開機。LCD屏會抖動。
2秒后正常。上下電時序按照規格書配置。

可能是啥原因？你們有碰到過嗎？

LCD之mipi DSI接口驅動調試流程
2.3.3、panel電荷無法釋放導致閃屏 --- 硬件設計

1.思路就是在lcd prepare期間判斷是dsi接口屏就給mipi控制器reset一下。
由于lcd不能直接調用mipi控制器接口，我就自己定義了一條特殊的mipi指令，在mipi控制器驅動那邊收到這條指令后進行reset操作。

rk3568和rk3588 ubuntu系統休眠喚醒后顯示異常

復位完成后，馬上寫入參數，可能會造成寫入不成功。
解決方案：
在dts文件里面加入init-delay-ms = <50>;

步驟一：使用邏輯分析儀或示波器按驅動IC的上下電時序測試對應引腳，特別是電源、RST、D0+、D0-，若實測整機開關機及其Power鍵休眠喚醒的時序無法滿足驅動IC的要求則需按驅動IC的要求調整整機驅動更新時序；
