beaglebone black 可以驅動 800X1280嗎

可以，我驱动过

请问具体是什么型号，刷新率是多少。

我们有客户可以接1280x960的屏

感謝~~

60Hz

使用瀚彩的...已經可點亮的

但是現在有24bits問題 Bit 16~Bit23都沒信號

这个需要配置寄存器将LCD控制器设置成RGB888输出

可否有參考code嗎

请问是用的TI官方发布的Linux SDK么？修改下驱动参数就可以了

请问您打算使用什么os？

TI原升版 4.2.2

畫面灰階不良

请问您根据lcd的参数配置过时序吗？

lcd_data14可否跟lcd_data15 可swap嗎( PCB layout 錯造成色階異常)

没看到TRM上有说可以swap，应该是不能更改的，需要改版了

感謝...跳線完..OK了

還有個問題

使用TI網路原生版的TI_Android_JB_4.2.2_DEvKit_4.1.1的bin

在SD CARD燒錄根據http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide

執行 sudo ./mkmmc-android.sh /dev/sd<sd card mount-point> MLO u-boot.img uImage uEnv.txt rootfs.tar.bz2 Media_Clips

無法patition正確磁區,請求指教...謝謝

有没有什么log信息，发上来看看。

估计是读卡器有问题

使用空的SDCARD

之前事先用linaro tool先分割後再執行一次

sudo ./mkmmc-android.sh /dev/sdc MLO u-boot.img uImage uEnv.txt rootfs.tar.bz2 Media_Clips

最近又不行..請您幫各忙..謝謝

印象里虚拟机上SD 卡都是映射的/dev/sdb，你ls下看看到底映射成什么设备了

先收尋到 /dev/sdc

再執行 .sh檔

結果如附圖
