该程序只支持toybrick板子，其他3399pro板子无法运行.
toybrick板子请烧写最新debian10固件用debian10的 ...

原生板子+原生固件+这个demo我们之前测试过的，并且其他客户也都这么演示的，并没有出现过问题，请问你有没有修改了什么东西？

sudo运行，并且尝试从串口或ssh运行试试

RK1808M0可以用toybrick库吗?我安装了toybrick,运行实例报错如下:

1.     import toybrick as toy
   
2.   File "/home/toybrick/.local/lib/python3.7/site-packages/toybrick/__init__.py", line 26, in <module>
   
3.     from toybrick.rtsp import  RtspClient
   
4.   File "/home/toybrick/.local/lib/python3.7/site-packages/toybrick/rtsp.py", line 1, in <module>
   
5.     from . import rkrtspclient
   
6. ImportError: libEGL.so: cannot open shared object file: No such file or directory

可以试试debian10的demo

可以试试debian10的demo

感谢回复,我是按照debian10给的方式安装的

1. sudo apt install rockchip-mpp
   
2. sudo apt install toybrick-gbm-dev
   
3. sudo toybrick-mali.sh link
   
4. pip3 install xxxxxx.whl

复制代码
但是在RK1808M0上导入toybrick依然报错

1. ImportError: libEGL.so: cannot open shared object file: No such file or directory

复制代码

我又尝试在RK3399(也是debian10)上安装toybrick,导入时报错

1. File "/usr/local/lib/python3.7/dist-packages/toybrick/__init__.py", line 24, in <module>
   
2.     from toybrick import graphic_buffer
   
3.   File "/usr/local/lib/python3.7/dist-packages/toybrick/graphic_buffer.py", line 1, in <module>
   
4.     from . import rkbuffer
   
5. SystemError: initialization of rkbuffer did not return an extension module

这个mali库就是libmali_gbm.so的，通过这个库渲染的就是通过DRM显示的。
然后mali还有libmali_x11.so和li ...

您好，我系统debian10，开发板RK3399pro。
我使用了您给的样例，出现Abort 如下：
Hello, World!
* EGL_VERSION = 1.4 Midgard-"r13p0-00rel0" (have 22 configs)
main 172  gbmSurface=0x55ca5ac5c0
Aborted。
该段代码是，请问是什么原因，或则您的代码是在什么平台上运行的。
    gbmSurface = gbm_surface_create(gbm, kms.mode.hdisplay, kms.mode.vdisplay,
                            GBM_FORMAT_XRGB8888,
                            GBM_BO_USE_SCANOUT | GBM_BO_USE_RENDERING);
    fprintf(stderr, "%s %d gbmSurface=%p\n",__func__,__LINE__, gbmSurface);

    eglSurface = eglCreateWindowSurface(eglDisplay, eglConfig, gbmSurface, NULL);

怎么读取一个静态图片，然后在这里显示呢？ 谢谢

已搞定
    buf = toy.GraphicBuffer(w, h, toy.GraphicFormat.FMT_RGB888)
    bg_img = np.zeros((h, w, 3), np.uint8)
    bg_img[:,:,0] = 0
    bg_img[:,:,1] = 255
    bg_img[:,:,2] = 0
    buf.memcpy_from(bg_img)

failed to open drm buffer !
一定要加sudo权限吗？

使用sudo权限运行的话，rknn环境又不可以了，
