兄弟你在板子上跑了那些需要opencv库的示例工程了吗?我按你的方法也能把这些示例工程成功编译了，但是我把一些示例工程弄到板子上就跑不起来，不是程序卡住就是没检测到目标。但跑一些不带opencv库的示例工程就可以成功跑出来。

编译ncnn时报错发布在 MR Series
回复: 又在全志d1开发板上玩ncnn
按照大佬的操作下载并且修改了V2.2.2工具链，修改了cmake toolchain，同时在~/.bashrc文件中添加了RISCV_ROOT_PATH，cmake正常，但make时报错：

@hu487364 我没有做你这个操作，我编译成功后，通过-L和-I链接了编译jpeg库生成好的头文件和库，然后记得加上-ljpeg，如下图：

回复: D1哪吒开发板默认输出改成HDMI发布在 MR Series
@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 。 -
设备树board.dts问题咨询发布在 MR Series
tina-d1-open/device/config/chips/d1/configs/nezha目录下有一个board.dts
tina-d1-open/device/config/chips/d1/configs/nezha/linux-5.4目录下也有个board.dts，看大家修改设备树文件的时候都是修改的后者。请问前者是干嘛的？ -
如何单独编译uboot发布在 MR Series
修改了uboot-board.dts之后准备单独编译uboot,在lichee/brandy-2.0/u-boot-2018应该执行什么命令？make clean和make吗？
-
回复: D1哪吒开发板默认输出改成HDMI发布在 MR Series
@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？ -

小白求助：交叉编译jpeg-9e时报错发布在 MR Series
由于程序需要的jpeg相关库交叉编译工具链没有提供，需要自己添加，就在网上下载了jpeg-9e的压缩包并解压，由于需要交叉编译，需要对configure默认的参数做修改，参照网上大佬，故作以下修改
主要修改了CC和LD，路径应该是正确的，参照下图：
不清楚他报错的原因。我同时也尝试先./configure生成makefile文件，然后对makefile文件做类似的修改，但也会报错
但我对ld和host都做了修改如下：
实在搞不懂，请各位大佬指点一下 -

小白求助，hdmi相关发布在 MR Series
目前准备把usb摄像头输出缓冲区的图片信息显示在hdmi屏幕上。
现在的思路是，先烧写官方提供的hdmi固件，即是做好了驱动和设备树的配置，这时只要往framebuffer写入数据，即执行写好的交叉编译好的程序，hdmi屏上就可以显示。（以上纯粹是自己的猜想，若不是这样，请大佬们指出错误）
程序大概就是把framebuffer指向usb输出缓冲区的地址，这其中用到的函数是我在D1-H Tina Linux Display开发指南中看到的。但文档中并没有给出这些函数的头文件，函数如下图：
如果以上思路大体正确，那有哪位大佬知道这些函数的头文件是什么，感谢。
大概十多分钟后报这个错误，请问是什么配置问题，我用的虚拟机。
我超级终端没反应
