D1哪吒开发板默认输出改成HDMI
-
因为没有钱买官方的MIPI屏幕，所以只能用HDMI屏幕来玩，但是默认源码和官方提供的固件默认输出都是MIPI的虽然在线文档里有提供切换成HDMI输出的方法，但是自己真正做的时候，还是需要把默认输出改成HDMI，于是有了此贴，记录小白摸索怎么改HDMI的过程，之前在另外一位朋友的帖子下提问，现在切过来自己开一贴，以免影响人家的时间线。
另外一个朋友的帖子传送门：
请问哪吒 D1 开发板拔插 HDMI 显示器, 提示sink do not support this mode 是什么问题? 换了两台显示器了. -
根据官方在线文档的介绍，其实可以开机后命令行手动切：
cd /sys/kernel/debug/dispdbg echo disp0 > name; echo switch1 > command; echo 4 10 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;在线文档传送门：

换华为的2K电视屏, 也是一样的问题.

把uboot-board.dts文件下的dev0_output_type改成4之后，默认输出倒是改成HDMI了，就是logo显示不正常，现在是一片绿色：

@tigger 应该不是，但是驱动参数配置可能用的一套，所以我也这样配了，确实输出了HDMI，但是输出还没正确

这么改完开机logo默认就从我插着的HDMI显示器输出了
但是好像还有一点问题，就是我cat colorbar的时候，颜色不太对，有点绿，好像是跟我一开始那个ev0_output_type改成4之后打印的绿色重合了，才有了这个效果：
-
我先用在线文档介绍的方法切到HDMI输出：

有朋友提到用我以上的修改还是会绿屏（满屏绿那种），我回忆了一下修改点，我之前是改掉了原SDK自带那个哪吒的启动logo，改成了linux小企鹅，大家可以把tina/device/config/chips/d1/configs/nezha/config 下面的bootlogo.bmp文件替换成下面这个文件试试：
bootlogo.7z
（文件是小企鹅启动logo）
（之前改掉启动logo是因为哪吒那张图3M多太大了，我不是故意改掉不告诉你们的。。。。） -
@xiaowenge 赞，搭顺风车问下，这个企鹅是240320的黑底的照片，背景也是黑色的，这种显示比较好，如果我是白底的400400这种的，背景颜色应该怎么设置呢

看了下配置文件注释，好像没有配置背景颜色这么一说（当然也可能是有但是配置文件没有更新，具体要读一下驱动源码）
如果不是黑底的话，应该是P一整张适配整个屏幕大小的开机log吧，这样才不会有色差

@xiaowenge 替换了还不行，可以帮忙试下拉v1.01的新codebase然后试下你的修改吗？

@xiaowenge 你好，我也在改hdmi，修改了uboot-board.dts后就来到lichee/brandy-2.0/u-boot-2018单独编译uboot
请问不是直接输入这两天命令吗？ -
@lumen 先在根目录
source build/envsetup.sh然后lunch才能用这两个命令 -

@yuzukitsuru 在cboot和muboot之前还要make clean吗？

理论上不需要clean，cleane一下也行，不影响，会保险一点，只不过重新编译要比较久。

@xiaowenge 请问设备树文件中dev0_screen_id代表什么？我按照你的修改之后，HDMI能够成功显示。如下，（我只需要720p所以mode改成了4）：
但我之前改的时候把dev0_screen_id改成了1，我理解的是这样dev0就对应了screen1，就同时修改了screen1的相关参数，具体如下：
但并未正常显示 。
