官方5.5寸mipi屏幕lubuntu 驱动问题
在firefly开发板上,本人新买了官方的5.5寸屏,由于对linux熟悉,官方又没有移植5.5寸lubuntu的驱动,因此自己打算移植,折腾的也有一星期了,现在遇到以下问题。
一:自己移植的驱动无法启动内核问题
使用内核:默认板内核,已更新到最新
参考http://wiki.t-firefly.com/index.php/Firefly-RK3288/DSI和pad版5.5寸mipi屏幕驱动
参考了lcd-ips5k0350fpc-mipi.dtsi文件,pad内核中的RK3288.dtsi和firefly-rk3288.dts文件,主要做了以下修改:
1 修改默认版内核RK3288.dtsi文件:修改如下:
主要修改了LCDC0,LCDC1部分,见下图1
2 修改了firefly-rk3288.dts文件
添加了头文件#include "lcd-ips5k0350fpc-mipi.dtsi",屏蔽了//#include "lcd-box.dtsi"
修改了LCDC0和LCDC1部分,见下图2
3 修改了firefly-rk3288-linux_defconfig
添加了如下:
CONFIG_LCD_MIPI=y
CONFIG_MIPI_DSI=y
CONFIG_RK32_MIPI_DSI=y
4 拷贝了lcd-ips5k0350fpc-mipi.dtsi到arch/arm/boot/dts目录
5 执行make distclean清理,然后执行了make firefly-rk3288-linux_defconfig配置和编译
首先板子烧写了Firefly-RK3288_Ubuntu14.04_201501271612.img能正常工作,我只是更新了Resource和boot部分,发现一直重启,进入不了系统,如下:怎么回事,希望版主解答下:

一直循环打印这些,启动不了内核!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
二:使用pad版内核无法挂载文件系统
如果不使用默认内核,使用pad内核,按照make firefly-rk3288-linux_defconfig进行配置编译
发现会出现两个问题
1,串口打印了Starting kernel ...就无输出了
2,无法挂载文件系统,会出现和这个帖子一样的问题

跪求版主解答哈
