mrtos_menuconfig出错了。

@lovexulu 你好近进也在研究这个，能一起聊下吗？qq545818496

@baiwen 这是啥，我这咋什么都没显示出来。

@akimizu 他们正在录视频。下下周应该会有。

请问t113 tina linux，这种问题怎么解决呢？纠结好久了

t527 板子一开机网口灯就亮，网线都没插灯就亮这不正常吧。

烧录android固件后，HDMI没任何显示。然后自己编译的android固件卡这里

。

买来的一直没用。我的T527还能用吗？

请问一下Avaota A1 T527开发板Android SDK网盘失效了。

lcd_gpio_0 = <&pio PE 11 GPIO_ACTIVE_HIGH>;
lcd_vsync = <&pio PD 21 2 0 3 0>;
//lcd_vsync  = port:PD21<2><0><3><default>
pinctrl-0 = <&dsi4lane_pins_a>;
pinctrl-1 = <&dsi4lane_pins_b>;

设备树这样写，好像没起到作用。

请问一下，屏显示有撕裂，TE脚要怎么使用呢？

uboot下配置好mipi屏（设备树和初始化）后，卡在uboot了。请问uboot下驱动mipi屏有什么依赖吗或先决条件吗，还是要怎么配置呢？

按照上面方法内核崩了。也没有动画出现。

@hsinyuwang 我用的是芒果派的tina linux,它支持SDL_DOUBLEBUF吗？

请问你开启了SDL双缓冲SDL_DOUBLEBUF了吗？

我测试提示段错误。是还要配置什么环境的吗？
screen = SDL_SetVideoMode(480, 32, 16, SDL_SWSURFACE | SDL_DOUBLEBUF);

请问tina linux SDL1.2.15 支持硬件双缓冲SDL_DOUBLEBUF吗？看到论坛里说支持

我测试提示段错误。是还要配置什么环境的吗？
screen = SDL_SetVideoMode(480, 32, 16, SDL_SWSURFACE | SDL_DOUBLEBUF);
